This is an Example of React Native Blinking Animation. Example contains :
- Making a CustomBlinkingTxt with blinking animation.
- Use CustomBlinkingTxt in our App Class.
- Pass the text using props.
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
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 | /*This is an Example of React Native Blinking Animation */ import React, { Component } from 'react'; //import react in our project import { Text, View } from 'react-native'; //import all the components we needed class CustomBlinkingTxt extends Component { constructor(props) { super(props); this.state = { showText: true }; // Change the state every second or the time given by User. setInterval(() => { this.setState(previousState => { return { showText: !previousState.showText }; }); }, // Define blinking time in milliseconds 1000 ); } render() { let display = this.state.showText ? this.props.text : ' '; return ( <Text style={{ textAlign: 'center', marginTop: 10 }}>{display}</Text> ); } } export default class App extends Component { render() { return ( <View style={{flex:1, alignContent:'center',justifyContent: 'center', padding:20}}> <CustomBlinkingTxt text="Lorem Ipsum is simply dummy text of the printing.." /> </View> ); } } |
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).IOS
Android
