- Around line 833-834: Update the remaining-time calculation in the press-out
flow to use the effective animation duration, applying the same
`getAnimatorDurationScale()` behavior used by `animatePressOut`. Keep the
existing conditions for deciding whether to defer PressOut, so its timing
matches the animation at every duration scale.
- Line 746: In the button handler’s bounds re-entry path, flush any queued
PressOut before dispatching PressIn so the events remain correctly ordered;
locate this logic near dispatchPressOut(handler).

I'm not a fan of the name of this prop, though I cannot say what exactly feels wrong. Maybe something along the lines of delayPressOutForAnimation?
Not a blocker. We can also brainstorm later.

I'd suggest delayPressOutUntilAnimationEnds, but delayPressOutForAnimation sounds ok. We can decide later.

I feel like we should delay this as well if we're delaying onPressOut, no?

Yes, we should. Let me know what you think about 6066584
## Description `iOS` half of #4568. Inside `ScrollView` UIKit holds the touch for `delaysContentTouches` until it rules out a scroll, and a tap released within that window gets `touchesBegan` and `touchesEnded` delivered together, so `onPressIn` and `onPressOut` reach JS in one batch and feedback driven from them never shows. With `pressOutAfterAnimation`, a press deferred that way holds `onPressOut` until the press-in animation (`animationDuration`) has played, the same moment the native press-out animation starts. `onPress` is not delayed. A press UIKit did not defer keeps its native timing; RN's own lists turn `delaysContentTouches` off, so they are unaffected. ## Test plan <details> <summary>Tested on the following code:</summary> ```tsx import React, { useRef, useState } from 'react'; import { Animated, StyleSheet, Text, View } from 'react-native'; import { ScrollView, Touchable } from 'react-native-gesture-handler'; // `pressOutAfterAnimation` (#4515): both cards drive a custom scale animation from // onPressIn/onPressOut, inside a scrolling container. Tap them as briefly as you can. // "animated" counts the taps whose press-in animation ran to completion: Android presses // a quick tap on the UP, so without the prop onPressOut cancels the animation right away; // with the prop onPressOut waits until the press-in animation (animationDuration) has played. // The hold is measured from the native press, and the JS animation starts a few ms later, so // the press-in duration is given a margin over the JS animation to keep the counter exact. const ANIMATION_MS = 80; const PRESS_IN_MS = 120; function AnimatedCard({ withProp }: { withProp: boolean }) { const [taps, setTaps] = useState(0); const [animated, setAnimated] = useState(0); const scale = useRef(new Animated.Value(1)).current; const animateTo = (value: number, onDone?: () => void) => Animated.timing(scale, { toValue: value, duration: ANIMATION_MS, useNativeDriver: true, }).start(({ finished }) => finished && onDone?.()); return ( <Touchable animationDuration={{ in: PRESS_IN_MS, out: ANIMATION_MS }} pressOutAfterAnimation={withProp} onPressIn={() => animateTo(0.94, () => setAnimated((n) => n + 1))} onPressOut={() => animateTo(1)} onPress={() => setTaps((n) => n + 1)}> <Animated.View style={[ styles.card, withProp ? styles.cardWithProp : styles.cardWithoutProp, { transform: [{ scale }] }, ]}> <Text style={styles.cardTitle}> {withProp ?

Adds a new

When set and the platform deferred the press,onPressOutis held until the press-in animation (animationDuration) has played, the same moment the native press-out animation starts.onPressis not delayed, so on such taps the order isonPressIn,onPress,onPressOut, as in RN. A press the platform did not defer keeps its native timing.Pressablesets the prop and a 130 ms press-in to match RN'sminPressDuration.Test plan
