How can I handle multi-touch gestures in React Native?

You can use the PanResponder API in React Native to handle multi-touch gestures. It allows you to track multiple touches and respond accordingly.

Can you give me an example of using PanResponder?

Sure! Here's a simple example:

import React, { useRef } from 'react';
import { View, PanResponder } from 'react-native';

const MultiTouchExample = () => {
  const panResponder = useRef(
    PanResponder.create({
      onStartShouldSetPanResponder: () => true,
      onMoveShouldSetPanResponder: () => true,
      onPanResponderMove: (evt, gestureState) => {
        console.log('Touches:', evt.nativeEvent.touches);
      },
    })
  ).current;

  return <View {...panResponder.panHandlers} style={{ flex: 1 }} />;
};

This will log the touches on the screen.

What if I want to handle pinch and zoom gestures?

For pinch and zoom, you can use the onPinchGesture method from the react-native-gesture-handler library. It provides a more comprehensive way to handle gestures.

Is there a way to combine multiple gestures?

Yes, you can combine gestures using the GestureDetector from react-native-gesture-handler. This allows you to recognize multiple gestures simultaneously.
