Flip Image View Horizontally Using Animation in React Native

Flip Image View Using Animation

This is an Example to Flip Image View Horizontally Using Animation in React Native. We are using the property of Animated Component from react-native.

To flip the image view horizontally using animation, We will flip the image on the click of Button. So let’s get started.

To Make a React Native App

Getting started with React Native will help you to know more about the way you can make a React Native project. We are going to use react-native init to make our React Native App. Assuming that you have node installed, you can use npm to install the react-native-cli command line utility. Open the terminal and go to the workspace and run

npm install -g react-native-cli

Run the following commands to create a new React Native project

react-native init ProjectName

If you want to start a new project with a specific React Native version, you can use the --version argument:

react-native init ProjectName --version X.XX.X
react-native init ProjectName --version react-native@next

This will make a project structure with an index file named App.js in your project directory.

Code

Open App.js in any code editor and replace the code with the following code.

App.js

/*This is an Example of React Native Flip Image Horizontally Using Animation*/
import React, { Component } from 'react';

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

export default class App extends Component {
  constructor() {
    super();
    this.animatedValue = new Animated.Value(0);
    this.value = 0;
    this.animatedValue.addListener(({ value }) => {
      this.value = value;
    });
  }
  flip_Animation = () => {
    if (this.value >= 90) {
      Animated.spring(this.animatedValue, {
        toValue: 0,
        tension: 10,
        friction: 8,
      }).start();
    } else {
      Animated.spring(this.animatedValue, {
        toValue: 180,
        tension: 10,
        friction: 8,
      }).start();
    }
  };
  render() {
    this.SetInterpolate = this.animatedValue.interpolate({
      inputRange: [0, 180],
      outputRange: ['180deg', '360deg'],
    });
    const Rotate_Y_AnimatedStyle = {
      transform: [{ rotateY: this.SetInterpolate }],
    };
    return (
      <View style={styles.MainContainer}>
        <Animated.Image
          source={{
            uri:
              'https://raw.githubusercontent.com/AboutReact/sampleresource/master/desktop-computer-screen-with-arrow-to-the-left-and-coin-stack.png',
          }}
          style={[Rotate_Y_AnimatedStyle, styles.imageStyle]}
        />
        <TouchableOpacity style={styles.button} onPress={this.flip_Animation}>
          <Text style={styles.TextStyle}> Click Here To Flip The Image </Text>
        </TouchableOpacity>
      </View>
    );
  }
}

const styles = StyleSheet.create({
  MainContainer: {
    flex: 1,
    alignItems: 'center',
    justifyContent: 'center',
  },
  imageStyle: {
    width: 150,
    height: 150,
    borderRadius: 6,
  },
  button: {
    width: '80%',
    backgroundColor: '#BAF5B5',
    borderRadius: 6,
    marginTop: 20,
  },
  TextStyle: {
    color: '#000',
    textAlign: 'center',
    padding: 5,
    fontSize: 18,
  },
});

To Run the React Native App

Open the terminal again and jump into your project using.
cd ProjectName
To run the project on an Android Virtual Device or on real debugging device
react-native run-android
or on the iOS Simulator by running
react-native run-ios (macOS only).
