This is an Example to Switch from One Screen to another using React Navigation 3.+ (Router). We will use react-navigation library for the Navigation.
React Native Navigation (Version 3+) is used to switch from one screen to another in the desired manner. This navigation solution is written entirely in JavaScript (so you can read and understand all of the sources), on top of powerful native primitives.
This is the updated post for the React Navigation Version 3+
Navigate using
1 | this.props.navigation.navigate('SecondPage') |
In this example, we will navigate from the first screen to second on a click of a 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-cliRun the following commands to create a new React Native project
react-native init ProjectNameIf 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.Xreact-native init ProjectName --version react-native@nextThis will make a project structure with an index file named App.js in your project directory.
Installation of Dependencies
To use createStackNavigator you need to install react-navigation and react-native-gesture-handler dependencies.
To install these dependencies open the terminal and jump into your project
1 | cd ProjectName |
Run the following commands
1 | npm install react-navigation --save |
1 | npm install react-native-gesture-handler --save |
This command will copy all the dependencies into your node_module directory. –save is optional, it is just to update dependencies in your package.json file.
CocoaPods Installation
After the updation of React Native 0.60, they have introduced autolinking so we do not require to link the library but need to install pods. So to install pods use
1 | cd ios && pod install && cd .. |
Project Structure
To start with this Example you need to create a directory named pages in your project and create two files FirstPage.js and SecondPage.js
Now 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 | //This is an example code for Navigator// import React, { Component } from 'react'; //import react in our code. //For React Navigation Version 2+ //import {createStackNavigator} from 'react-navigation'; //For React Navigation Version 3+ import {createStackNavigator,createAppContainer} from 'react-navigation'; //import Navigator in our project import FirstPage from './pages/FirstPage'; import SecondPage from './pages/SecondPage'; //import all the screens we are going to switch const App = createStackNavigator({ //Constant which holds all the screens like index of any book FirstPage: { screen: FirstPage }, //First entry by default be our first screen if we do not define initialRouteName SecondPage: { screen: SecondPage }, }, { initialRouteName: 'FirstPage', } ); //Version 3+ changes are here. //In version 2+ createAppContainer was default container //but in version 3+ you have to export it manually //For React Navigation Version 2+ //export default App; //For React Navigation Version 3+ export default createAppContainer(App); |
Open FirstPage.js in any code editor and replace the code with the following code.
FirstPage.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 37 38 39 40 41 | //This is an example code for Navigator// import React, { Component } from 'react'; //import react in our code. import { StyleSheet, View, Button} from 'react-native'; //import all the components we are going to use. export default class FirstPage extends Component { static navigationOptions = { title: 'First Page', //Sets Header text of Status Bar headerStyle: { backgroundColor: '#f4511e', //Sets Header color }, headerTintColor: '#fff', //Sets Header text color headerTitleStyle: { fontWeight: 'bold', //Sets Header text style }, }; render() { const { navigate } = this.props.navigation; return ( <View style={styles.container}> <Button title='Go next' onPress={() =>navigate('SecondPage')} /> </View> ); } } const styles = StyleSheet.create({ container: { flex: 1, backgroundColor: '#fff', alignItems: 'center', justifyContent: 'center', }, }); |
Open SecondPage.js in any code editor and replace the code with the following code.
SecondPage.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 | //This is an example code for Navigator// import React, { Component } from 'react'; //import react in our code. import { StyleSheet, View, Text} from 'react-native'; //import all the components we are going to use. export default class SecondPage extends Component { static navigationOptions = { title: 'Second Page', //Sets Header text of Status Bar }; render() { const { navigate } = this.props.navigation; return ( <View style={styles.container}> <Text>You are on SecondPage</Text> </View> ); } } const styles = StyleSheet.create({ container: { flex: 1, backgroundColor: '#fff', margin:50, alignItems: 'center', justifyContent: 'center', }, }); |
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

Hi,
I’m trying to pass two functions in a button (TouchableOpacity)to trigger two events. 1.) store data from Input in a AsyncStorage and 2.) navigate to a new site.
Actually I want to take the Input, it’s a number and call a file to open as a new site. Fore example: I have store (in AsyncStorage or SQLite) 10 different pattern. Every pattern has a number. Input will give the number as a value -> than navigate to a new site and bring up the desired pattern.
The problem is: when I put in the navigation into onPress={() => this.props.navigation.navigate(‘Pattern’)} I can’t pass any other function in.
How to fix it?
Thank you, Peter
Suggestion 1:
You don’t need to use any storage type of thing for that you can pass the value in navigation itself and can get the value on another screen.
1. Send Value from first screen using :
navigate(‘SecondPage’, { value: ‘https://aboutreact.com’ })
2. Get Value on Second Screen:
constructor(props) {
super(props);
const {params} = this.props.navigation.state;
alert(params.value);
///Here will be the key which you have used to sent
}
Please have a look at the example below.

Suggestion 2:
You can use GlobalScope variable to do that thing. Set the Global variable and access it from the other screen. Please find the Example here https://aboutreact.com/react-native-global-scope-variables/
Please revert if you are still facing the issue.
