How can I implement advanced gestures in React Native using Reanimated?

You can implement advanced gestures in React Native using the Reanimated library by utilizing the Gesture Handler and Reanimated together. Start by installing both libraries.

What are some common gestures I can implement?

Common gestures include pinch, pan, rotate, and swipe. You can create complex interactions by combining these gestures.

Can you show me a code example for a pinch gesture?

Sure! Here's a simple example:

import { PinchGestureHandler } from 'react-native-gesture-handler';
import Animated, { useSharedValue, useAnimatedStyle } from 'react-native-reanimated';

const MyComponent = () => {
  const scale = useSharedValue(1);

  const onPinchEvent = Animated.event([{ nativeEvent: { scale: scale } }], { useNativeDriver: true });

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

  return (
    <PinchGestureHandler onGestureEvent={onPinchEvent}>
      <Animated.View style={[styles.box, animatedStyle]} />
    </PinchGestureHandler>
  );
};

This will allow you to pinch to zoom in and out.

What if I want to combine pinch and pan gestures?

You can combine gestures by nesting them. Use the GestureDetector to wrap both pinch and pan handlers, allowing simultaneous gestures.
