What does the Gesture Responder System do?

The Gesture Responder System in React Native is a mechanism that allows an application to handle and respond to user interactions, managing the entire lifecycle of gestures. This system is essential for determining how touch events are processed and which components should respond to these events.

Key Functions of the Gesture Responder System:

1. Lifecycle Management: It manages the lifecycle of gestures, from the initial touch to the end of the interaction. This includes determining whether a touch is a single tap, a scroll, or another type of gesture[1][6].

2. Responder Negotiation: The system allows components to negotiate touch interactions without needing additional knowledge about their parent or child components. This is achieved through a series of methods that decide whether a view should become the responder to a touch event[6].

3. Feedback and Highlighting: It provides mechanisms to give users feedback, such as highlighting the touched component, which enhances the user experience by making interactions more intuitive[6].

4. Touchables: React Native includes built-in APIs called Touchables (e.g., TouchableHighlight, TouchableOpacity, TouchableWithoutFeedback) that use the Gesture Responder System to capture gestures and provide visual feedback[1].

5. Event Handling Methods:

   • onStartShouldSetResponder: Determines if a view should respond to the initial touch.
   • onMoveShouldSetResponder: Determines if a view should respond to touch movements.
   • onResponderGrant: Called when a view becomes the responder.
   • onResponderMove: Called when the touch moves.
   • onResponderRelease: Called when the touch ends.
   • onResponderTerminate: Called when the responder status is taken away from a view[1][6].

Example Usage:

import React from 'react';
import { View, Text, StyleSheet } from 'react-native';

const MyComponent = () => {
  const handleStartShouldSetResponder = (evt) => true;
  const handleMoveShouldSetResponder = (evt) => true;
  const handleRespo...
