animation gesture detector press

Use GestureDetector for Animated Press States

For animated press states (scale, opacity on press), use GestureDetector with Gesture.Tap() and shared values instead of Pressable's onPressIn/onPressOut. Gesture callbacks run on the UI thread as worklets—no JS thread round-trip for press animations.

Incorrect (Pressable with JS thread callbacks):

  useSharedValue,
  useAnimatedStyle,
  withTiming,
} from 'react-native-reanimated'

function AnimatedButton({ onPress }: { onPress: () => void }) {
  const scale = useSharedValue(1)

  const animatedStyle = useAnimatedStyle(() => ({
    transform: [{ scale: scale.value }],
  }))

  return (
     (scale.value = withTiming(0.95))}
      onPressOut={() => (scale.value = withTiming(1))}
    >
      <Animated.View style={animatedStyle}>
        Press me
      </Animated.View>
    
  )
}

Correct (GestureDetector with UI thread worklets):

  useSharedValue,
  useAnimatedStyle,
  withTiming,
  interpolate,
  runOnJS,
} from 'react-native-reanimated'

function AnimatedButton({ onPress }: { onPress: () => void }) {
  // Store the press STATE (0 = not pressed, 1 = pressed)
  const pressed = useSharedValue(0)

  const tap = Gesture.Tap()
    .onBegin(() => {
      pressed.set(withTiming(1))
    })
    .onFinalize(() => {
      pressed.set(withTiming(0))
    })
    .onEnd(() => {
      runOnJS(onPress)()
    })

  // Derive visual values from the state
  const animatedStyle = useAnimatedStyle(() => ({
    transform: [
      { scale: interpolate(withTiming(pressed.get()), [0, 1], [1, 0.95]) },
    ],
  }))

  return (
    
      <Animated.View style={animatedStyle}>
        Press me
      </Animated.View>
    
  )
}

Store the press state (0 or 1), then derive the scale via interpolate. This keeps the shared value as ground truth. Use runOnJS to call JS functions from worklets. Use .set() and .get() for React Compiler compatibility.
