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+ . According to the official release “it now depends on react-native-gesture-handler. This library provides an excellent set of primitives for leveraging the operating systems’ native gesture APIs and has enabled us to fix a variety of issues with stack and drawer navigators.”
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 thereact-native-cli command line utility.
Open the terminal and go to the workspace and runnpm install -g react-native-clireact-native init ProjectNameInstallation 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.
Linking of Dependencies
After installing the dependencies you need to link it with your project using
1 | react-native link react-native-gesture-handler |
After linking the dependency if you face Could not Compile Settings File project/android/settings.gradle error while building and installing the project then you can find the solution here.
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.
Change in this example as compared to our previous example on React Navigation (Version 2+) is:
In Version 2+ you just need to export the default class.
1 | export default App; |
But In Version 3+ you have to wrap it with the createAppContainer and then you have to export it.
1 | export default createAppContainer(App); |
For this, you have to import createAppContainer from ‘react-navigation’. Have a look at the updated code. We are using “react-navigation”: “3.0.8” for this example.
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.

Here is the link to download the code:

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.
