variable TouchableHighlight

const TouchableHighlight: React.ForwardRefExoticComponent<any>;

A wrapper for making views respond properly to touches. On press down, the opacity of the wrapped view is decreased, which allows the underlay color to show through, darkening or tinting the view. The underlay comes from adding a view to the view hierarchy, which can sometimes cause unwanted visual artifacts if not used correctly, for example if the backgroundColor of the wrapped view isn't explicitly set to an opaque color.
NOTE: TouchableHighlight supports only one child If you wish to have several child components, wrap them in a View.

Functions

function DynamicColorIOS

DynamicColorIOS: (tuple: DynamicColorIOSTuple) => OpaqueColorValue;

Specify color to display depending on the current system appearance settings
Parameter tuple
Colors you want to use for "light mode" and "dark mode" ios

function findNodeHandle

findNodeHandle: (
    componentOrHandle:
        | null
        | number
        | React.Component<any, any>
        | React.ComponentClass<any>
) => null | NodeHandle;

function PlatformColor

PlatformColor: (...colors: string[]) => OpaqueColorValue;

See Also
- https://reactnative.dev/docs/platformcolor#example

function processColor

processColor: (
    color?: number | ColorValue
) => ProcessedColorValue | null | undefined;

function requireNativeComponent

requireNativeComponent: <T>(viewName: string) => HostComponent<T>;

Creates values that can be used like React components which represent native view managers. You should create JavaScript modules that wrap these values so that the results are memoized. Example:
const View = requireNativeComponent('RCTView');
The concrete return type of requireNativeComponent is a string, but the declared type is HostComponent because TypeScript assumes anonymous JSX intrinsics (e.g. a string) not to have any props.

function unstable_batchedUpdates

unstable_batchedUpdates: {
    <A, R>(callback: (a: A) => R, a: A): R;
    <R>(callback: () => R): R;
};

React Native also implements unstable_batchedUpdates

function useAnimatedValue

useAnimatedValue: (
    initialValue: number,
    config?: Animated.AnimatedConfig
) => Animated.Value;

function useColorScheme

useColorScheme: () => ColorSchemeName;

A new useColorScheme hook is provided as the preferred way of accessing the user's preferred color scheme (e.g. Dark Mode).

function useWindowDimensions

useWindowDimensions: () => ScaledSize;

property SIZE

static SIZE: Object;

class RefreshControlComponent

class RefreshControlComponent extends React.Component<RefreshControlProps> {}

This component is used inside a ScrollView or ListView to add pull to refresh functionality. When the ScrollView is at scrollY: 0, swiping down triggers an onRefresh event.
__Note:__ refreshing is a controlled prop, this is why it needs to be set to true in the onRefresh function otherwise the refresh indicator will stop immediately.

class SafeAreaView

class SafeAreaViewComponent

class SafeAreaViewComponent extends React.Component<ViewProps> {}

Renders nested content and automatically applies paddings reflect the portion of the view that is not covered by navigation bars, tab bars, toolbars, and other ancestor views. Moreover, and most importantly, Safe Area's paddings reflect physical limitation of the screen, such as rounded corners or camera notches (aka sensor housing area on iPhone X).

getInnerViewNode: () => any;

method getScrollableNode

getScrollableNode: () => any;

method getScrollResponder

getScrollResponder: () => ScrollResponderMixin;

Returns a reference to the underlying scroll responder, which supports operations like scrollTo. All ScrollView-like components should implement this method so that they can be composed while providing access to the underlying scroll responder's methods.

method scrollTo

scrollTo: (
    y?:
        | number
        | {
              x?: number | undefined;

              animated?: boolean | undefined;
          },
    deprecatedX?: number,
    deprecatedAnimated?: boolean
) => void;

Scrolls to a given x, y offset, either immediately or with a smooth animation. Syntax:
scrollTo(options: {x: number = 0; y: number = 0; animated: boolean = true})
Note: The weird argument signature is due to the fact that, for historical reasons, the function also accepts separate arguments as an alternative to the options object. This is deprecated due to ambiguity (y before x), and SHOULD NOT BE USED.

method scrollToEnd

scrollToEnd: (options?: { animated?: boolean | undefined }) => void;

A helper function that scrolls to the end of the scrollview; If this is a vertical ScrollView, it scrolls to the bottom. If this is a horizontal ScrollView scrolls to the right.
The options object has an animated prop, that enables the scrolling animation or not. The animated prop defaults to true

method setNativeProps

setNativeProps: (nativeProps: object) => void;

This function sends props straight to native. They will not participate in future diff process - this means that if you do not include them in the next render, they will remain active (see [Direct Manipulation](https://reactnative.dev/docs/direct-manipulation)).

Launches an alert dialog with the specified title and message.
Optionally provide a list of buttons. Tapping any button will fire the respective onPress callback and dismiss the alert. By default, the only button will be an 'OK' button.
This is an API that works both on iOS and Android and can show static alerts. On iOS, you can show an alert that prompts the user to enter some information.
## iOS
On iOS you can specify any number of buttons. Each button can optionally specify a style, which is one of 'default', 'cancel' or 'destructive'.
## Android
On Android at most three buttons can be specified. Android has a concept of a neutral, negative and a positive button:
- If you specify one button, it will be the 'positive' one (such as 'OK') - Two buttons mean 'negative', 'positive' (such as 'Cancel', 'OK') - Three buttons mean 'neutral', 'negative', 'positive' (such as 'Later', 'Cancel', 'OK')
// Works on both iOS and Android Alert.alert( 'Alert Title', 'My Alert Msg', [ {text: 'Ask me later', onPress: () => console.log('Ask me later pressed')}, {text: 'Cancel', onPress: () => console.log('Cancel Pressed'), style: 'cancel'}, {text: 'OK', onPress: () => console.log('OK Pressed')}, ] )

When this happens, children won't receive the tap. - 'always', the keyboard will not dismiss automatically, and the scroll view will not catch taps, but children of the scroll view can catch taps. - 'handled', the keyboard will not dismiss automatically when the tap was handled by a children, (or captured by an ancestor). - false, deprecated, use 'never' instead - true, deprecated, use 'always' instead

property keyExtractor

keyExtractor?: ((item: ItemT, index: number) => string) | undefined;

interface GestureResponderEvent

interface GestureResponderEvent extends NativeSyntheticEvent<NativeTouchEvent> {}

interface GestureResponderHandlers

interface GestureResponderHandlers {}

Gesture recognition on mobile devices is much more complicated than web. A touch can go through several phases as the app determines what the user's intention is. For example, the app needs to determine if the touch is scrolling, sliding on a widget, or tapping. This can even change during the duration of a touch. There can also be multiple simultaneous touches.
The touch responder system is needed to allow components to negotiate these touch interactions without any additional knowledge about their parent or child components. This system is implemented in ResponderEventPlugin.js, which contains further details and documentation.
Best Practices Users can feel huge differences in the usability of web apps vs. native, and this is one of the big causes. Every action should have the following attributes: Feedback/highlighting- show the user what is handling their touch, and what will happen when they release the gesture Cancel-ability- when making an action, the user should be able to abort it mid-touch by dragging their finger away
These features make users more comfortable while using an app, because it allows people to experiment and interact without fear of making mistakes.
TouchableHighlight and Touchable* The responder system can be complicated to use. So we have provided an abstract Touchable implementation for things that should be "tappable". This uses the responder system and allows you to easily configure tap interactions declaratively. Use TouchableHighlight anywhere where you would use a button or link on web.

property onMoveShouldSetResponder

onMoveShouldSetResponder?:
    | ((event: GestureResponderEvent) => boolean)
    | undefined;

Called for every touch move on the View when it is not the responder: does this view want to "claim" touch responsiveness?

property onMoveShouldSetResponderCapture

onMoveShouldSetResponderCapture?:
    | ((event: GestureResponderEvent) => boolean)
    | undefined;

onStartShouldSetResponder and onMoveShouldSetResponder are called with a bubbling pattern, where the deepest node is called first. That means that the deepest component will become responder when multiple Views return true for *ShouldSetResponder handlers. This is desirable in most cases, because it makes sure all controls and buttons are usable.
However, sometimes a parent will want to make sure that it becomes responder. This can be handled by using the capture phase. Before the responder system bubbles up from the deepest component, it will do a capture phase, firing on*ShouldSetResponderCapture. So if a parent View wants to prevent the child from becoming responder on a touch start, it should have a onStartShouldSetResponderCapture handler which returns true.

property onResponderEnd

onResponderEnd?: ((event: GestureResponderEvent) => void) | undefined;

If the View returns true and attempts to become the responder, one of the following will happen:

property onResponderGrant

onResponderGrant?: ((event: GestureResponderEvent) => void) | undefined;

The View is now responding for touch events. This is the time to highlight and show the user what is happening

property onResponderMove

onResponderMove?: ((event: GestureResponderEvent) => void) | undefined;

The user is moving their finger

property onResponderReject

onResponderReject?: ((event: GestureResponderEvent) => void) | undefined;

Something else is the responder right now and will not release it

property onResponderRelease

onResponderRelease?: ((event: GestureResponderEvent) => void) | undefined;

Fired at the end of the touch, ie "touchUp"

property onResponderStart

onResponderStart?: ((event: GestureResponderEvent) => void) | undefined;

property onResponderTerminate

onResponderTerminate?: ((event: GestureResponderEvent) => void) | undefined;

The responder has been taken from the View. Might be taken by other views after a call to onResponderTerminationRequest, or might be taken by the OS without asking (happens with control center/ notification center on iOS)

property onResponderTerminationRequest

onResponderTerminationRequest?:
    | ((event: GestureResponderEvent) => boolean)
    | undefined;

Something else wants to become responder. Should this view release the responder? Returning true allows release

property onStartShouldSetResponder

onStartShouldSetResponder?:
    | ((event: GestureResponderEvent) => boolean)
    | undefined;

Does this view want to become responder on the start of a touch?

property onStartShouldSetResponderCapture

onStartShouldSetResponderCapture?:
    | ((event: GestureResponderEvent) => boolean)
    | undefined;

onStartShouldSetResponder and onMoveShouldSetResponder are called with a bubbling pattern, where the deepest node is called first. That means that the deepest component will become responder when multiple Views return true for *ShouldSetResponder handlers. This is desirable in most cases, because it makes sure all controls and buttons are usable.
However, sometimes a parent will want to make sure that it becomes responder. This can be handled by using the capture phase.

Determine whether or not an installed app can handle a given URL. NOTE: For web URLs, the protocol ("http://", "https://") must be set accordingly! NOTE: As of iOS 9, your app needs to provide the LSApplicationQueriesSchemes key inside Info.plist.
Parameter URL
the URL to open

method getInitialURL

getInitialURL: () => Promise<string | null>;

If the app launch was triggered by an app link with, it will give the link url, otherwise it will give null NOTE: To support deep linking on Android, refer http://developer.android.com/training/app-indexing/deep-linking.html#handling-intents

method openSettings

openSettings: () => Promise<void>;

Open the Settings app and displays the app’s custom settings, if it has any.

method openURL

interface NativeEventSubscription

interface NativeEventSubscription {}

method remove

remove: () => void;

Call this method to un-subscribe from a native-event

interface NativeMethods

interface NativeMethods {}

NativeMethods provides methods to access the underlying native component directly. This can be useful in cases when you want to focus a view or measure its on-screen dimensions, for example. The methods described here are available on most of the default components provided by React Native. Note, however, that they are not available on composite components that aren't directly backed by a native view. This will generally include most components that you define in your own app. For more information, see [Direct Manipulation](https://reactnative.dev/docs/direct-manipulation).

};

method blur

blur: () => void;

Removes focus from an input or view. This is the opposite of focus().

method focus

focus: () => void;

Requests focus for the given input or view. The exact behavior triggered will depend on the platform and type of view.

method measure

measure: (callback: MeasureOnSuccessCallback) => void;

Determines the location on screen, width, and height of the given view and returns the values via an async callback. If successful, the callback will be called with the following arguments:
- x - y - width - height - pageX - pageY
Note that these measurements are not available until after the rendering has been completed in native. If you need the measurements as soon as possible, consider using the [onLayout prop](docs/view.html#onlayout) instead.

method measureInWindow

measureInWindow: (callback: MeasureInWindowOnSuccessCallback) => void;

Determines the location of the given view in the window and returns the values via an async callback. If the React root view is embedded in another native view, this will give you the absolute coordinates. If successful, the callback will be called with the following arguments:
- x - y - width - height
Note that these measurements are not available until after the rendering has been completed in native.

method measureLayout

measureLayout: (
    relativeToNativeComponentRef:
        | React.ElementRef<HostComponent<unknown>>
        | number,
    onSuccess: MeasureLayoutOnSuccessCallback,
    onFail?: () => void
) => void;

Like [measure()](#measure), but measures the view relative an ancestor, specified as relativeToNativeComponentRef. This means that the returned x, y are relative to the origin x, y of the ancestor view. _Can also be called with a relativeNativeNodeHandle but is deprecated._

method setNativeProps

setNativeProps: (nativeProps: object) => void;

This function sends props straight to native. They will not participate in future diff process - this means that if you do not include them in the next render, they will remain active (see [Direct Manipulation](https://reactnative.dev/docs/direct-manipulation)).

interface PanResponderInstance

property panHandlers

interface PanResponderStatic

interface PanResponderStatic {}

PanResponder reconciles several touches into a single gesture. It makes single-touch gestures resilient to extra touches, and can be used to recognize simple multi-touch gestures.
It provides a predictable wrapper of the responder handlers provided by the gesture responder system. For each handler, it provides a new gestureState object alongside the normal event.

method create

create: (config: PanResponderCallbacks) => PanResponderInstance;

Parameter config
Enhanced versions of all of the responder callbacks that provide not only the typical ResponderSyntheticEvent, but also the PanResponder gesture state. Simply replace the word Responder with PanResponder in each of the typical onResponder* callbacks. For example, the config object would look like:
- onMoveShouldSetPanResponder: (e, gestureState) => {...} - onMoveShouldSetPanResponderCapture: (e, gestureState) => {...} - onStartShouldSetPanResponder: (e, gestureState) => {...} - onStartShouldSetPanResponderCapture: (e, gestureState) => {...} - onPanResponderReject: (e, gestureState) => {...} - onPanResponderGrant: (e, gestureState) => {...} - onPanResponderStart: (e, gestureState) => {...} - onPanResponderEnd: (e, gestureState) => {...} - onPanResponderRelease: (e, gestureState) => {...} - onPanResponderMove: (e, gestureState) => {...} - onPanResponderTerminate: (e, gestureState) => {...} - onPanResponderTerminationRequest: (e, gestureState) => {...} - onShouldBlockNativeResponder: (e, gestureState) => {...}
In general, for events that have capture equivalents, we update the gestureState once in the capture phase and can use it in the bubble phase as well.
Be careful with onStartShould* callbacks. They only reflect updated gestureState for start/end events that bubble/capture to the Node. Once the node is the responder, you can rely on every start/end event being processed by the gesture and gestureState being updated accordingly. (numberActiveTouches) may not be totally accurate unless you are the responder.

method componentWillMount

componentWillMount: () => void;

componentWillMount is the closest thing to a standard "constructor" for React components.
The keyboardWillShow is called before input focus.

method scrollResponderGetScrollableNode

scrollResponderGetScrollableNode: () => any;

Returns the node that represents native view that can be scrolled. Components can pass what node to use by defining a getScrollableNode function otherwise this is used.

method scrollResponderHandleMomentumScrollBegin

scrollResponderHandleMomentumScrollBegin: (e: ScrollResponderEvent) => void;

Invoke this from an onMomentumScrollBegin event.

method scrollResponderHandleMomentumScrollEnd

scrollResponderHandleMomentumScrollEnd: (e: ScrollResponderEvent) => void;

Invoke this from an onMomentumScrollEnd event.

method scrollResponderHandleResponderGrant

scrollResponderHandleResponderGrant: (e: ScrollResponderEvent) => void;

Invoke this from an onResponderGrant event.

method scrollResponderHandleResponderReject

scrollResponderHandleResponderReject: () => any;

Invoke this from an onResponderReject event.
Some other element is not yielding its role as responder. Normally, we'd just disable the UIScrollView, but a touch has already began on it, the UIScrollView will not accept being disabled after that. The easiest solution for now is to accept the limitation of disallowing this altogether. To improve this, find a way to disable the UIScrollView after a touch has already started.

method scrollResponderHandleResponderRelease

scrollResponderHandleResponderRelease: (e: ScrollResponderEvent) => void;

Invoke this from an onResponderRelease event.

method scrollResponderHandleScroll

scrollResponderHandleScroll: (e: ScrollResponderEvent) => void;

method scrollResponderHandleScrollBeginDrag

scrollResponderHandleScrollBeginDrag: (e: ScrollResponderEvent) => void;

Unfortunately, onScrollBeginDrag also fires when *stopping* the scroll animation, and there's not an easy way to distinguish a drag vs. stopping momentum.
Invoke this from an onScrollBeginDrag event.

method scrollResponderHandleScrollEndDrag

scrollResponderHandleScrollEndDrag: (e: ScrollResponderEvent) => void;

Invoke this from an onScrollEndDrag event.

method scrollResponderHandleScrollShouldSetResponder

scrollResponderHandleScrollShouldSetResponder: () => boolean;

Invoke this from an onScroll event.

method scrollResponderHandleStartShouldSetResponder

scrollResponderHandleStartShouldSetResponder: () => boolean;

Merely touch starting is not sufficient for a scroll view to become the responder. Being the "responder" means that the very next touch move/end event will result in an action/movement.
Invoke this from an onStartShouldSetResponder event.
onStartShouldSetResponder is used when the next move/end will trigger some UI movement/action, but when you want to yield priority to views nested inside of the view.
There may be some cases where scroll views actually should return true from onStartShouldSetResponder: Any time we are detecting a standard tap that gives priority to nested views.
- If a single tap on the scroll view triggers an action such as recentering a map style view yet wants to give priority to interaction views inside (such as dropped pins or labels), then we would return true from this method when there is a single touch.
- Similar to the previous case, if a two finger "tap" should trigger a zoom, we would check the touches count, and if >= 2, we would return true.

method scrollResponderHandleStartShouldSetResponderCapture

scrollResponderHandleStartShouldSetResponderCapture: (
    e: ScrollResponderEvent
) => boolean;

There are times when the scroll view wants to become the responder (meaning respond to the next immediate touchStart/touchEnd), in a way that *doesn't* give priority to nested views (hence the capture phase):
- Currently animating. - Tapping anywhere that is not the focused input, while the keyboard is up (which should dismiss the keyboard).
Invoke this from an onStartShouldSetResponderCapture event.

method scrollResponderHandleTerminationRequest

scrollResponderHandleTerminationRequest: () => boolean;

We will allow the scroll view to give up its lock iff it acquired the lock during an animation. This is a very useful default that happens to satisfy many common user experiences.
- Stop a scroll on the left edge, then turn that into an outer view's backswipe. - Stop a scroll mid-bounce at the top, continue pulling to have the outer view dismiss. - However, without catching the scroll view mid-bounce (while it is motionless), if you drag far enough for the scroll view to become responder (and therefore drag the scroll view a bit), any backswipe navigation of a swipe gesture higher in the view hierarchy, should be rejected.

method scrollResponderHandleTouchEnd

scrollResponderHandleTouchEnd: (e: ScrollResponderEvent) => void;

Invoke this from an onTouchEnd event.
Parameter e
Event.

method scrollResponderHandleTouchMove

scrollResponderHandleTouchMove: (e: ScrollResponderEvent) => void;

Invoke this from an onTouchMove event.
Since we know that the SimpleEventPlugin occurs later in the plugin order, after ResponderEventPlugin, we can detect that we were *not* permitted to be the responder (presumably because a contained view became responder). The onResponderReject won't fire in that case - it only fires when a *current* responder rejects our request.
Parameter e
Touch Start event.

method scrollResponderHandleTouchStart

scrollResponderHandleTouchStart: (e: ScrollResponderEvent) => void;

Invoke this from an onTouchStart event.
Since we know that the SimpleEventPlugin occurs later in the plugin order, after ResponderEventPlugin, we can detect that we were *not* permitted to be the responder (presumably because a contained view became responder). The onResponderReject won't fire in that case - it only fires when a *current* responder rejects our request.
Parameter e
Touch Start event.

method scrollResponderInputMeasureAndScrollToKeyboard

scrollResponderInputMeasureAndScrollToKeyboard: (
    left: number,
    top: number,
    width: number,
    height: number
) => void;

The calculations performed here assume the scroll view takes up the entire screen - even if has some content inset. We then measure the offsets of the keyboard, and compensate both for the scroll view's "contentInset".
Parameter left
Position of input w.r.t. table view.
Parameter top
Position of input w.r.t. table view.
Parameter width
Width of the text input.
Parameter height
Height of the text input.

method scrollResponderIsAnimating

A helper function for this class that lets us quickly determine if the view is currently animating. This is particularly useful to know when a touch has just started or ended.

method scrollResponderKeyboardDidHide

scrollResponderKeyboardDidHide: (e: ScrollResponderEvent) => void;

method scrollResponderKeyboardDidShow

scrollResponderKeyboardDidShow: (e: ScrollResponderEvent) => void;

method scrollResponderKeyboardWillHide

scrollResponderKeyboardWillHide: (e: ScrollResponderEvent) => void;

method scrollResponderKeyboardWillShow

scrollResponderKeyboardWillShow: (e: ScrollResponderEvent) => void;

Warning, this may be called several times for a single keyboard opening. It's best to store the information in this method and then take any action at a later point (either in keyboardDidShow or other).
Here's the order that events occur in: - focus - willShow {startCoordinates, endCoordinates} several times - didShow several times - blur - willHide {startCoordinates, endCoordinates} several times - didHide several times
The ScrollResponder providesModule callbacks for each of these events. Even though any user could have easily listened to keyboard events themselves, using these props callbacks ensures that ordering of events is consistent - and not dependent on the order that the keyboard events are subscribed to. This matters when telling the scroll view to scroll to where the keyboard is headed - the scroll responder better have been notified of the keyboard destination before being instructed to scroll to where the keyboard will be. Stick to the ScrollResponder callbacks, and everything will work.
WARNING: These callbacks will fire even if a keyboard is displayed in a different navigation pane. Filter out the events to determine if they are relevant to you. (For example, only if you receive these callbacks after you had explicitly focused a node etc).

method scrollResponderScrollNativeHandleToKeyboard

scrollResponderScrollNativeHandleToKeyboard: (
    nodeHandle: any,
    additionalOffset?: number,
    preventNegativeScrollOffset?: boolean
) => void;

This method should be used as the callback to onFocus in a TextInputs' parent view. Note that any module using this mixin needs to return the parent view's ref in getScrollViewRef() in order to use this method.
Parameter nodeHandle
The TextInput node handle
Parameter additionalOffset
The scroll view's top "contentInset". Default is 0.
Parameter preventNegativeScrolling
Whether to allow pulling the content down to make it meet the keyboard's top. Default is false.

method scrollResponderScrollTo

scrollResponderScrollTo: (
    x?:
        | number
        | {
              x?: number | undefined;
              y?: number | undefined;
              animated?: boolean | undefined;
          },
    y?: number,
    animated?: boolean
) => void;

A helper function to scroll to a specific point in the scrollview. This is currently used to help focus on child textviews, but can also be used to quickly scroll to any element we want to focus. Syntax:
scrollResponderScrollTo(options: {x: number = 0; y: number = 0; animated: boolean = true})
Note: The weird argument signature is due to the fact that, for historical reasons, the function also accepts separate arguments as an alternative to the options object. This is deprecated due to ambiguity (y before x), and SHOULD NOT BE USED.

method scrollResponderTextInputFocusError

scrollResponderTextInputFocusError: (e: ScrollResponderEvent) => void;

method scrollResponderZoomTo

scrollResponderZoomTo: (
    rect: {
        x: number;
        y: number;

        height: number;
        animated?: boolean | undefined;
    },
    animated?: boolean
) => void;

A helper function to zoom to a specific rect in the scrollview. The argument has the shape {x: number; y: number; width: number; height: number; animated: boolean = true}

interface ScrollViewProps

interface ScrollViewProps
    extends ViewProps,
        ScrollViewPropsIOS,
        ScrollViewPropsAndroid,
        Touchable {}

property contentContainerStyle

contentContainerStyle?: StyleProp<ViewStyle> | undefined;

These styles will be applied to the scroll view content container which wraps all of the child views. Example:
return ( <ScrollView contentContainerStyle={styles.contentContainer}> ); ... const styles = StyleSheet.create({ contentContainer: { paddingVertical: 20 } });

property decelerationRate

decelerationRate?: 'fast' | 'normal' | number | undefined;

A floating-point number that determines how quickly the scroll view decelerates after the user lifts their finger. You may also use string shortcuts "normal" and "fast" which match the underlying iOS settings for UIScrollViewDecelerationRateNormal and UIScrollViewDecelerationRateFast respectively.
- 'normal': 0.998 on iOS, 0.985 on Android (the default) - 'fast': 0.99 on iOS, 0.9 on Android

property disableIntervalMomentum

disableIntervalMomentum?: boolean | undefined;

When true, the scroll view stops on the next index (in relation to scroll position at release) regardless of how fast the gesture is. This can be used for horizontal pagination when the page is less than the width of the ScrollView. The default value is false.

property disableScrollViewPanResponder

disableScrollViewPanResponder?: boolean | undefined;

When true, the default JS pan responder on the ScrollView is disabled, and full control over touches inside the ScrollView is left to its child components. This is particularly useful if snapToInterval is enabled, since it does not follow typical touch patterns. Do not use this on regular ScrollView use cases without snapToInterval as it may cause unexpected touches to occur while scrolling. The default value is false.

property horizontal

horizontal?: boolean | null | undefined;

When true the scroll view's children are arranged horizontally in a row instead of vertically in a column. The default value is false.

property invertStickyHeaders

invertStickyHeaders?: boolean | undefined;

If sticky headers should stick at the bottom instead of the top of the ScrollView. This is usually used with inverted ScrollViews.

property keyboardDismissMode

keyboardDismissMode?: 'none' | 'interactive' | 'on-drag' | undefined;

Determines whether the keyboard gets dismissed in response to a drag. - 'none' (the default) drags do not dismiss the keyboard. - 'onDrag' the keyboard is dismissed when a drag begins. - 'interactive' the keyboard is dismissed interactively with the drag and moves in synchrony with the touch; dragging upwards cancels the dismissal.

property keyboardShouldPersistTaps

keyboardShouldPersistTaps?: boolean | 'always' | 'never' | 'handled' | undefined;

Determines when the keyboard should stay visible after a tap. - 'never' (the default), tapping outside of the focused text input when the keyboard is up dismisses the keyboard. When this happens, children won't receive the tap. - 'always', the keyboard will not dismiss automatically, and the scroll view will not catch taps, but children of the scroll view can catch taps. - 'handled', the keyboard will not dismiss automatically when the tap was handled by a children, (or captured by an ancestor). - false, deprecated, use 'never' instead - true, deprecated, use 'always' instead

property onContentSizeChange

onContentSizeChange?: ((w: number, h: number) => void) | undefined;

    | undefined;

Fires when a user has finished scrolling.

property pagingEnabled

property refreshControl

refreshControl?: React.ReactElement<RefreshControlProps> | undefined;

A RefreshControl component, used to provide pull-to-refresh functionality for the ScrollView.

property removeClippedSubviews

removeClippedSubviews?: boolean | undefined;

Experimental: When true offscreen child views (whose overflow value is hidden) are removed from their native backing superview when offscreen. This can improve scrolling performance on long lists. The default value is false.

property scrollEnabled

scrollEnabled?: boolean | undefined;

When false, the content does not scroll. The default value is true

property showsHorizontalScrollIndicator

showsHorizontalScrollIndicator?: boolean | undefined;

When true, shows a horizontal scroll indicator.

property showsVerticalScrollIndicator

showsVerticalScrollIndicator?: boolean | undefined;

When true, shows a vertical scroll indicator.

property snapToEnd

snapToEnd?: boolean | undefined;

Use in conjunction with snapToOffsets. By default, the end of the list counts as a snap offset. Set snapToEnd to false to disable this behavior and allow the list to scroll freely between its end and the last snapToOffsets offset. The default value is true.

property snapToInterval

snapToInterval?: number | undefined;

When set, causes the scroll view to stop at multiples of the value of snapToInterval. This can be used for paginating through children that have lengths smaller than the scroll view. Used in combination with snapToAlignment and decelerationRate="fast". Overrides less configurable pagingEnabled prop.

property snapToOffsets

When set, causes the scroll view to stop at the defined offsets. This can be used for paginating through variously sized children that have lengths smaller than the scroll view. Typically used in combination with decelerationRate="fast". Overrides less configurable pagingEnabled and snapToInterval props.

property snapToStart

snapToStart?: boolean | undefined;

Use in conjunction with snapToOffsets. By default, the beginning of the list counts as a snap offset. Set snapToStart to false to disable this behavior and allow the list to scroll freely between its start and the first snapToOffsets offset. The default value is true.

property StickyHeaderComponent

StickyHeaderComponent?: React.ComponentType<any> | undefined;

A React Component that will be used to render sticky headers, should be used together with stickyHeaderIndices.

Style

interface ScrollViewPropsAndroid

interface ScrollViewPropsAndroid {}

property endFillColor

endFillColor?: ColorValue | undefined;

Sometimes a scrollview takes up more space than its content fills. When this is the case, this prop will fill the rest of the scrollview with a color to avoid setting a background and creating unnecessary overdraw. This is an advanced optimization that is not needed in the general case.

property fadingEdgeLength

fadingEdgeLength?: number | undefined;

property contentInset

contentInset?: Insets | undefined;

The amount by which the scroll view content is inset from the edges of the scroll view. Defaults to {0, 0, 0, 0}.

property contentInsetAdjustmentBehavior

contentInsetAdjustmentBehavior?:
    | 'automatic'
    | 'scrollableAxes'
    | 'never'
    | 'always'
    | undefined;

This property specifies how the safe area insets are used to modify the content area of the scroll view. The default value of this property must be 'automatic'. But the default value is 'never' until RN@0.51.

property maintainVisibleContentPosition

maintainVisibleContentPosition?:
    | null
    | {
          autoscrollToTopThreshold?: number | null | undefined;
          minIndexForVisible: number;
      }
    | undefined;

When set, the scroll view will adjust the scroll position so that the first child that is currently visible and at or beyond minIndexForVisible will not change position. This is useful for lists that are loading content in both directions, e.g. a chat thread, where new messages coming in might otherwise cause the scroll position to jump. A value of 0 is common, but other values such as 1 can be used to skip loading spinners or other content that should not maintain position.
The optional autoscrollToTopThreshold can be used to make the content automatically scroll to the top after making the adjustment if the user was within the threshold of the top before the adjustment was made. This is also useful for chat-like applications where you want to see new messages scroll into place, but not if the user has scrolled up a ways and it would be disruptive to scroll a bunch.
Caveat 1: Reordering elements in the scrollview with this enabled will probably cause jumpiness and jank. It can be fixed, but there are currently no plans to do so. For now, don't re-order the content of any ScrollViews or Lists that use this feature.
Caveat 2: This uses contentOffset and frame.origin in native code to compute visibility. Occlusion, transforms, and other complexity won't be taken into account as to whether content is "visible" or not.

property value

value?: string | undefined;

The value to show for the text input. TextInput is a controlled component, which means the native value will be forced to match this value prop if provided. For most uses this works great, but in some cases this may cause flickering - one common cause is preventing edits by keeping value the same. In addition to simply setting the same value, either set editable={false}, or set/update maxLength to prevent unwanted edits without flicker.

Returns the amount to extend the HitRect into the PressRect. Positive numbers mean the size expands outwards.

method touchableHandleActivePressIn

touchableHandleActivePressIn: (e: GestureResponderEvent) => void;

Invoked when the item should be highlighted. Mixers should implement this to visually distinguish the VisualRect so that the user knows that releasing a touch will result in a "selection" (analog to click).

method touchableHandleActivePressOut

touchableHandleActivePressOut: (e: GestureResponderEvent) => void;

Invoked when the item is "active" (in that it is still eligible to become a "select") but the touch has left the PressRect. Usually the mixer will want to unhighlight the VisualRect. If the user (while pressing) moves back into the PressRect touchableHandleActivePressIn will be invoked again and the mixer should probably highlight the VisualRect again. This event will not fire on an touchEnd/mouseUp event, only move events while the user is depressing the mouse/touch.

method touchableHandleLongPress

touchableHandleLongPress: (e: GestureResponderEvent) => void;

Invoked when the item is long pressed - meaning the interaction ended by letting up while the item was in RESPONDER_ACTIVE_LONG_PRESS_IN. If touchableHandleLongPress is *not* provided, touchableHandlePress will be called as it normally is. If touchableHandleLongPress is provided, by default any touchableHandlePress callback will not be invoked. To override this default behavior, override touchableLongPressCancelsPress to return false. As a result, touchableHandlePress will be called when lifting up, even if touchableHandleLongPress has also been called.

method touchableHandlePress

touchableHandlePress: (e: GestureResponderEvent) => void;

Invoked when the item is "selected" - meaning the interaction ended by letting up while the item was either in the state RESPONDER_ACTIVE_PRESS_IN or RESPONDER_INACTIVE_PRESS_IN.

property background

background?: BackgroundPropType | undefined;

Determines the type of background drawable that's going to be used to display feedback. It takes an object with type property and extra data depending on the type. It's recommended to use one of the following static methods to generate that dictionary: 1) TouchableNativeFeedback.SelectableBackground() - will create object that represents android theme's default background for selectable elements (?android:attr/selectableItemBackground) 2) TouchableNativeFeedback.SelectableBackgroundBorderless() - will create object that represent android theme's default background for borderless selectable elements (?android:attr/selectableItemBackgroundBorderless). Available on android API level 21+ 3) TouchableNativeFeedback.Ripple(color, borderless) - will create object that represents ripple drawable with specified color (as a string). If property borderless evaluates to true the ripple will render outside of the view bounds (see native actionbar buttons as an example of that behavior). This background type is available on Android API level 21+

property id

id?: string | undefined;

Used to reference react managed views from native code.

property onBlur

onBlur?: ((e: NativeSyntheticEvent<TargetedEvent>) => void) | undefined;

When accessible is true (which is the default) this may be called when the OS-specific concept of "blur" occurs, meaning the element lost focus. Some platforms may not have the concept of blur.

property hasViewManagerConfig

hasViewManagerConfig: (name: string) => boolean;

property setLayoutAnimationEnabledExperimental

setLayoutAnimationEnabledExperimental?: ((value: boolean) => void) | undefined;

Automatically animates views to their new positions when the next layout happens.
A common way to use this API is to call it before calling setState.
Note that in order to get this to work on **Android** you need to set the following flags via UIManager:
UIManager.setLayoutAnimationEnabledExperimental && UIManager.setLayoutAnimationEnabledExperimental(true);

method measure

measure: (node: number, callback: MeasureOnSuccessCallback) => void;

Determines the location on screen, width, and height of the given view and returns the values via an async callback. If successful, the callback will be called with the following arguments:
- x - y - width - height - pageX - pageY
Note that these measurements are not available until after the rendering has been completed in native. If you need the measurements as soon as possible, consider using the [onLayout prop](docs/view.html#onlayout) instead.
Deprecated
Use ref.measure instead.

method measureInWindow

measureInWindow: (
    node: number,
    callback: MeasureInWindowOnSuccessCallback
) => void;

Determines the location of the given view in the window and returns the values via an async callback. If the React root view is embedded in another native view, this will give you the absolute coordinates. If successful, the callback will be called with the following arguments:
- x - y - width - height
Note that these measurements are not available until after the rendering has been completed in native.
Deprecated
Use ref.measureInWindow instead.

method measureLayout

measureLayout: (
    node: number,
    relativeToNativeNode: number,
    onFail: () => void,
    onSuccess: MeasureLayoutOnSuccessCallback
) => void;

Like [measure()](#measure), but measures the view relative an ancestor, specified as relativeToNativeNode. This means that the returned x, y are relative to the origin x, y of the ancestor view.
As always, to obtain a native node handle for a component, you can use React.findNodeHandle(component).
Deprecated
Use ref.measureLayout instead.

interface VibrationStatic

interface VibrationStatic {}

The Vibration API is exposed at Vibration.vibrate(). The vibration is asynchronous so this method will return immediately.
There will be no effect on devices that do not support Vibration, eg. the simulator.
**Note for android** add <uses-permission android:name="android.permission.VIBRATE"/> to AndroidManifest.xml
**Android Usage:**
[0, 500, 200, 500] V(0.5s) --wait(0.2s)--> V(0.5s)
[300, 500, 200, 500] --wait(0.3s)--> V(0.5s) --wait(0.2s)--> V(0.5s)
**iOS Usage:** if first argument is 0, it will not be included in pattern array.
[0, 1000, 2000, 3000] V(fixed) --wait(1s)--> V(fixed) --wait(2s)--> V(fixed) --wait(3s)--> V(fixed)

method cancel

cancel: () => void;

Stop vibration

method vibrate

vibrate: (pattern?: number | number[], repeat?: boolean) => void;

interface ViewProps

interface ViewProps {}

property experimental_layoutConformance

experimental_layoutConformance?: 'strict' | 'classic' | undefined;

Contols whether this view, and its transitive children, are laid in a way consistent with web browsers ('strict'), or consistent with existing React Native code which may rely on incorrect behavior ('classic').

interface ViewPropsAndroid

interface ViewPropsAndroid {}

property collapsable

collapsable?: boolean | undefined;

Views that are only used to layout their children or otherwise don't draw anything may be automatically removed from the native hierarchy as an optimization. Set this property to false to disable this optimization and ensure that this View exists in the native view hierarchy.

property collapsableChildren

collapsableChildren?: boolean | undefined;

Setting to false prevents direct children of the view from being removed from the native view hierarchy, similar to the effect of setting collapsable={false} on each child.

property focusable

focusable?: boolean | undefined;

Whether this View should be focusable with a non-touch input device, eg. receive focus with a hardware keyboard.

property renderToHardwareTextureAndroid

renderToHardwareTextureAndroid?: boolean | undefined;

Whether this view should render itself (and all of its children) into a single hardware texture on the GPU.
On Android, this is useful for animations and interactions that only modify opacity, rotation, translation, and/or scale: in those cases, the view doesn't have to be redrawn and display lists don't need to be re-executed. The texture can just be re-used and re-composited with different parameters. The downside is that this can use up limited video memory, so this prop should be set back to false at the end of the interaction/animation.

property tabIndex

tabIndex?: 0 | -1 | undefined;

Indicates whether this View should be focusable with a non-touch input device, eg. receive focus with a hardware keyboard. See https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/tabindex for more details.
Supports the following values: - 0 (View is focusable) - -1 (View is not focusable)

interface ViewPropsIOS

interface ViewPropsIOS extends TVViewPropsIOS {}

property shouldRasterizeIOS

shouldRasterizeIOS?: boolean | undefined;

Whether this view should be rendered as a bitmap before compositing.
On iOS, this is useful for animations and interactions that do not modify this component's dimensions nor its children; for example, when translating the position of a static view, rasterization allows the renderer to reuse a cached bitmap of a static view and quickly composite it during each frame.
Rasterization incurs an off-screen drawing pass and the bitmap consumes memory. Test and measure when using this property.

AppState can tell you if the app is in the foreground or background, and notify you when the state changes.
AppState is frequently used to determine the intent and proper behavior when handling push notifications.
App State Events change - This even is received when the app state has changed. focus [Android] - Received when the app gains focus (the user is interacting with the app). blur [Android] - Received when the user is not actively interacting with the app.
App States active - The app is running in the foreground background - The app is running in the background. The user is either in another app or on the home screen inactive [iOS] - This is a transition state that happens when the app launches, is asking for permissions or when a call or SMS message is received. unknown [iOS] - Initial value until the current app state is determined extension [iOS] - The app is running as an app extension

variable ScrollView

const ScrollView: AnimatedComponent<typeof ScrollView>;

variable Text

const Text: AnimatedComponent<typeof Text>;

variable View

const View: AnimatedComponent<typeof View>;

Animated variants of the basic native views. Accepts Animated.Value for props and style.

function add

add: <OutputT extends string | number>(
    a: Animated,
    b: Animated
) => AnimatedAddition<OutputT>;

Creates a new Animated value composed from two Animated values added together.

function createAnimatedComponent

createAnimatedComponent: <T extends React.ComponentType<any>>(
    component: T,
    options?: AnimatedComponentOptions
) => AnimatedComponent<T>;

Make any React component Animatable. Used to create Animated.View, etc.

function decay

decay: (
    value: AnimatedValue | AnimatedValueXY,
    config: DecayAnimationConfig
) => CompositeAnimation;

Animates a value from an initial velocity to zero based on a decay coefficient.

function delay

delay: (time: number) => CompositeAnimation;

Starts an animation after the given delay.

function diffClamp

diffClamp: <OutputT extends string | number>(
    a: Animated,
    min: number,
    max: number
) => AnimatedDiffClamp<OutputT>;

Create a new Animated value that is limited between 2 values. It uses the difference between the last value so even if the value is far from the bounds it will start changing when the value starts getting closer again. (value = clamp(value + diff, min, max)).
This is useful with scroll events, for example, to show the navbar when scrolling up and to hide it when scrolling down.

function divide

divide: <OutputT extends string | number>(
    a: Animated,
    b: Animated
) => AnimatedDivision<OutputT>;

Creates a new Animated value composed by dividing the first Animated value by the second Animated value.

function event

event: <T>(
    argMapping: Array<Mapping | null>,
    config?: EventConfig<T>
) => (...args: any[]) => void;

Takes an array of mappings and extracts values from each arg accordingly, then calls setValue on the mapped outputs. e.g.

 onScroll={Animated.event(
   [{nativeEvent: {contentOffset: {x: this._scrollX}}}]
   {listener},          // Optional async listener
 )
 ...
 onPanResponderMove: Animated.event([
   null,                // raw event arg ignored
   {dx: this._panX},    // gestureState arg
 ]),

function loop

loop: (
    animation: CompositeAnimation,
    config?: LoopAnimationConfig
) => CompositeAnimation;

Loops a given animation continuously, so that each time it reaches the end, it resets and begins again from the start. Can specify number of times to loop using the key 'iterations' in the config. Will loop without blocking the UI thread if the child animation is set to 'useNativeDriver'.

function modulo

modulo: <OutputT extends string | number>(
    a: Animated,
    modulus: number
) => AnimatedModulo<OutputT>;

Creates a new Animated value that is the (non-negative) modulo of the provided Animated value

function multiply

multiply: <OutputT extends string | number>(
    a: Animated,
    b: Animated
) => AnimatedMultiplication<OutputT>;

Creates a new Animated value composed from two Animated values multiplied together.

function parallel

parallel: (
    animations: Array<CompositeAnimation>,
    config?: ParallelConfig
) => CompositeAnimation;

Starts an array of animations all at the same time. By default, if one of the animations is stopped, they will all be stopped. You can override this with the stopTogether flag.

function sequence

sequence: (animations: Array<CompositeAnimation>) => CompositeAnimation;

Starts an array of animations in order, waiting for each to complete before starting the next. If the current running animation is stopped, no following animations will be started.

function spring

spring: (
    value: AnimatedValue | AnimatedValueXY,
    config: SpringAnimationConfig
) => CompositeAnimation;

Spring animation based on Rebound and Origami. Tracks velocity state to create fluid motions as the toValue updates, and can be chained together.

function stagger

stagger: (
    time: number,
    animations: Array<CompositeAnimation>
) => CompositeAnimation;

Array of animations may run in parallel (overlap), but are started in sequence with successive delays. Nice for doing trailing effects.

function subtract

subtract: <OutputT extends string | number>(
    a: Animated,
    b: Animated
) => AnimatedSubtraction<OutputT>;

Creates a new Animated value composed by subtracting the second Animated value from the first Animated value.

function timing

timing: (
    value: AnimatedValue | AnimatedValueXY,
    config: TimingAnimationConfig
) => CompositeAnimation;

Animates a value along a timed easing curve. The Easing module has tons of pre-defined curves, or you can use your own function.

method addListener

addListener: (callback: (value: any) => any) => string;

Adds an asynchronous listener to the value so you can observe updates from animations. This is useful because there is no way to synchronously read the value because it might be driven natively.
See https://reactnative.dev/docs/animatedvalue.html#addlistener

method hasListeners

hasListeners: () => boolean;

class Value

class Value extends AnimatedWithChildren {}

Standard value for driving animations. One Animated.Value can drive multiple properties in a synchronized fashion, but can only be driven by one mechanism at a time. Using a new mechanism (e.g. starting a new animation, or calling setValue) will stop any previous ones.

constructor

constructor(value: number, config?: AnimatedConfig);

method addListener

addListener: (callback: ValueListenerCallback) => string;

Adds an asynchronous listener to the value so you can observe updates from animations. This is useful because there is no way to synchronously read the value because it might be driven natively.

method animate

animate: (animation: Animation, callback?: EndCallback | null) => void;

Typically only used internally, but could be used by a custom Animation class.
See https://reactnative.dev/docs/animatedvalue#animate

method extractOffset

extractOffset: () => void;

Sets the offset value to the base value, and resets the base value to zero. The final output of the value is unchanged.

method flattenOffset

flattenOffset: () => void;

Merges the offset value into the base value and resets the offset to zero. The final output of the value is unchanged.

method interpolate

interpolate: <OutputT extends string | number>(
    config: InterpolationConfigType
) => AnimatedInterpolation<OutputT>;

Interpolates the value before updating the property, e.g. mapping 0-1 to 0-10.

method removeAllListeners

removeAllListeners: () => void;

method removeListener

removeListener: (id: string) => void;

method resetAnimation

resetAnimation: (callback?: (value: number) => void) => void;

Stops any animation and resets the value to its original.
See https://reactnative.dev/docs/animatedvalue#resetanimation

method setOffset

setOffset: (offset: number) => void;

Sets an offset that is applied on top of whatever value is set, whether via setValue, an animation, or Animated.event. Useful for compensating things like the start of a pan gesture.

method setValue

setValue: (value: number) => void;

Directly set the value. This will stop any animations running on the value and update all the bound properties.

method stopAnimation

stopAnimation: (callback?: (value: number) => void) => void;

Stops any running animation or tracking. callback is invoked with the final value after stopping the animation, which is useful for updating state to match the animation position with layout.

class ValueXY

class ValueXY extends AnimatedWithChildren {}

2D Value for driving 2D animations, such as pan gestures. Almost identical API to normal Animated.Value, but multiplexed. Contains two regular Animated.Values under the hood.

constructor

constructor(
    valueIn?: { x: number | AnimatedValue; y: number | AnimatedValue },
    config?: AnimatedConfig
);

property x

x: Value;

property y

y: Value;

method addListener

addListener: (callback: ValueXYListenerCallback) => string;

method extractOffset

extractOffset: () => void;

method flattenOffset

flattenOffset: () => void;

method getLayout

getLayout: () => { [key: string]: Value };

Converts {x, y} into {left, top} for use in style, e.g.
style={this.state.anim.getLayout()}

method getTranslateTransform

getTranslateTransform: () => [
    { translateX: AnimatedValue },
    { translateY: AnimatedValue }
];

Converts {x, y} into a useable translation transform, e.g.

 style={{
   transform: this.state.anim.getTranslateTransform()
 }}

Animations are started by calling start() on your animation. start() takes a completion callback that will be called when the animation is done or when the animation is done because stop() was called on it before it could finish.
Parameter callback
Optional function that will be called after the animation finished running normally or when the animation is done because stop() was called on it before it could finish
Example 1
Animated.timing({}).start(({ finished }) => { // completion callback });

property stop

stop: () => void;

Stops any running animation.

namespace Appearance

namespace Appearance {}

function addChangeListener

addChangeListener: (listener: AppearanceListener) => NativeEventSubscription;

Add an event handler that is fired when appearance preferences change.

function getColorScheme

getColorScheme: () => ColorSchemeName;

Note: Although color scheme is available immediately, it may change at any time. Any rendering logic or styles that depend on this should try to call this function on every render, rather than caching the value (for example, using inline styles rather than setting a value in a StyleSheet).
Example: const colorScheme = Appearance.getColorScheme();

function setColorScheme

setColorScheme: (scheme: ColorSchemeName | null | undefined) => void;

Set the color scheme preference. This is useful for overriding the default color scheme preference for the app. Note that this will not change the appearance of the system UI, only the appearance of the app. Only available on iOS 13+ and Android 10+.

type AppearanceListener

type AppearanceListener = (preferences: AppearancePreferences) => void;

type AppearancePreferences

type AppearancePreferences = {
    colorScheme: ColorSchemeName;

namespace AppRegistry

namespace AppRegistry {}

AppRegistry is the JS entry point to running all React Native apps. App root components should register themselves with AppRegistry.registerComponent, then the native system can load the bundle for the app and then actually run the app when it's ready by invoking AppRegistry.runApplication.
To "stop" an application when a view should be destroyed, call AppRegistry.unmountApplicationComponentAtRootTag with the tag that was pass into runApplication. These should always be used as a pair.
AppRegistry should be required early in the require sequence to make sure the JS execution environment is setup before other modules are required.

namespace StyleSheet

namespace StyleSheet {}

variable absoluteFill

const absoluteFill: Number & { __registeredStyleBrand: AbsoluteFillStyle };

A very common pattern is to create overlays with position absolute and zero positioning, so absoluteFill can be used for convenience and to reduce duplication of these repeated styles.

variable absoluteFillObject

const absoluteFillObject: AbsoluteFillStyle;

Sometimes you may want absoluteFill but with a couple tweaks - absoluteFillObject can be used to create a customized entry in a StyleSheet, e.g.:
const styles = StyleSheet.create({ wrapper: { ...StyleSheet.absoluteFillObject, top: 10, backgroundColor: 'transparent', }, });

variable hairlineWidth

const hairlineWidth: number;

This is defined as the width of a thin line on the platform. It can be used as the thickness of a border or division between two elements. Example:
{ borderBottomColor: '#bbb', borderBottomWidth: StyleSheet.hairlineWidth }
This constant will always be a round number of pixels (so a line defined by it look crisp) and will try to match the standard width of a thin line on the underlying platform. However, you should not rely on it being a constant size, because on different platforms and screen densities its value may be calculated differently.

function compose

compose: <
    T extends ViewStyle | TextStyle | ImageStyle,
    U extends T,
    V extends T
>(
    style1: StyleProp<U> | Array<StyleProp<U>>,
    style2: StyleProp<V> | Array<StyleProp<V>>
) => StyleProp<T>;

Combines two styles such that style2 will override any styles in style1. If either style is falsy, the other one is returned without allocating an array, saving allocations and maintaining reference equality for PureComponent checks.

function create

create: <T extends NamedStyles<T> | NamedStyles<any>>(
    styles: T & NamedStyles<any>
) => T;

An identity function for creating style sheets.

function flatten

flatten: <T>(style?: StyleProp<T>) => T extends (infer U)[] ? U : T;

Flattens an array of style objects, into one aggregated style object.

Example:

const styles = StyleSheet.create({
  listItem: {
    flex: 1,
    fontSize: 16,
    color: 'white'
  },
  selectedListItem: {
    color: 'green'
  }
});

StyleSheet.flatten([styles.listItem, styles.selectedListItem])
// returns { flex: 1, fontSize: 16, color: 'green' }

function setStyleAttributePreprocessor

setStyleAttributePreprocessor: (
    property: string,
    process: (nextProp: any) => any
) => void;

WARNING: EXPERIMENTAL. Breaking changes will probably happen a lot and will not be reliably announced. The whole thing might be deleted, who knows? Use at your own risk.
Sets a function to use to pre-process a style property value. This is used internally to process color and transform values. You should not use this unless you really know what you are doing and have exhausted other options.

function beginAsyncEvent

beginAsyncEvent: (eventName: EventName, args?: EventArgs) => number;

Marks the start of a potentially asynchronous event. The end of this event should be marked calling the endAsyncEvent function with the cookie returned by this function.

function beginEvent

beginEvent: (eventName: EventName, args?: EventArgs) => void;

Marks the start of a synchronous event that should end in the same stack frame. The end of this event should be marked using the endEvent function.

function counterEvent

counterEvent: (eventName: EventName, value: number) => void;

counterEvent registers the value to the eventName on the systrace timeline

function endAsyncEvent

endAsyncEvent: (eventName: EventName, cookie: number, args?: EventArgs) => void;

Registers a new value for a counter event.

function endEvent

endEvent: (args?: EventArgs) => void;

Marks the end of a synchronous event started in the same stack frame.

function isEnabled

isEnabled: () => boolean;

Indicates if the application is currently being traced.
Calling methods on this module when the application isn't being traced is cheap, but this method can be used to avoid computing expensive values for those functions.
Example 1
if (Systrace.isEnabled()) { const expensiveArgs = computeExpensiveArgs(); Systrace.beginEvent('myEvent', expensiveArgs); }

function setEnabled

setEnabled: (_doEnable: boolean) => void;

Deprecated
This function is now a no-op but it's left for backwards compatibility. isEnabled will now synchronously check if we're actively profiling or not. This is necessary because we don't have callbacks to know when profiling has started/stopped on Android APIs.

type EventArgs = { [key: string]: string } | void | null;
