Flip Image View Horizontally Using Animation in React Native
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 image view horizontally using animation, We will flip the image on 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
Run the following commands to create a new React Native projectnpm install -g react-native-cli
This will make a project structure with an index file named App.js in your project directory.react-native init ProjectName
Open App.js in any code editor and replace the code with the following code.
App.js

To Run the React Native App
Open the terminal again and jump into your project using.cd ProjectNamereact-native run-androidreact-native run-ios (macOS only).
