The main code sample in React Hooks

[peterkortvel]

Hi, here is the same code as used in the code sample but with React Hooks:

import React, {Component} from 'react';
import {Text} from 'react-native';
import GestureRecognizer, {swipeDirections} from 'react-native-swipe-gestures';
 
export default function TestFile(){
    const [myText, setMyText] = React.useState('I\'m ready to get swiped!');
    const [gestureName, setGestureName] = React.useState('none');
    const [backgroundColor, setBackgroundColor] = React.useState('#fff');
 
  const onSwipeUp = (gestureState) => {
    setMyText('You swiped up!');
  }
 
  const onSwipeDown = (gestureState) => {
    setMyText('You swiped down!');
  }
 
  const onSwipeLeft = (gestureState) => {
    setMyText('You swiped left!');
  }
 
  const onSwipeRight = (gestureState) => {
    setMyText('You swiped right!');
  }
 
  const onSwipe = (gestureName, gestureState) => {
    const {SWIPE_UP, SWIPE_DOWN, SWIPE_LEFT, SWIPE_RIGHT} = swipeDirections;
    setGestureName(gestureName);
    switch (gestureName) {
      case SWIPE_UP:
        setBackgroundColor('red');
        break;
      case SWIPE_DOWN:
        setBackgroundColor('green');
        break;
      case SWIPE_LEFT:
        setBackgroundColor('blue');
        break;
      case SWIPE_RIGHT:
        setBackgroundColor('yellow');
        break;
    }
  }
 
  const config = {
    velocityThreshold: 0.3,
    directionalOffsetThreshold: 80
  };

  return (
    <GestureRecognizer
      onSwipe={(direction, state) => onSwipe(direction, state)}
      onSwipeUp={(state) => onSwipeUp(state)}
      onSwipeDown={(state) => onSwipeDown(state)}
      onSwipeLeft={(state) => onSwipeLeft(state)}
      onSwipeRight={(state) => onSwipeRight(state)}
      config={config}
      style={{
        flex: 1,
        backgroundColor: backgroundColor,
      }}
      >
      <Text>{myText}</Text>
      <Text>onSwipe callback received gesture: {gestureName}</Text>

    </GestureRecognizer>
  );
}
