Switch from One Screen to another using React Navigation 4.+ (Router)

Switch from One Screen to another using React Navigation 4.+ (Router)

This is an Example to Switch from One Screen to another using React Navigation 4.+ (Router). We will use react-navigation library for the Navigation.

React Native Navigation (Version 4+) 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 example is updated for the React Navigation 4.0+. For more about React Navigation 4 please have a look at Using React Navigation 4.0 in React Native apps.

Navigate using

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-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.

Installation of Dependencies

To switch between the screens we need to add react navigation in our application.

To install the dependencies open the terminal and jump into your project

1. Install react-navigation dependency to import createAppContainer

2. Install react-native-gesture-handler dependency to support gesture navigation

3. Install react-navigation-stack to import createStackNavigator

These commands will copy all the dependencies into your node_module directory.

CocoaPods Installation

After the updation of React Native 0.60, they have introduced autolinking so we do not require to link the libraries but need to install pods.

In this example we need to install the pods for react-native-gesture-handler.

Please use the following command to install CocoaPods

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

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

FirstPage.js

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

SecondPage.js

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).

IOS

     

Android

     

That was the React Native Navigation Version 4.+. If you have any doubt or you want to share something about the topic you can comment below or contact us here. There will be more posts coming soon. Stay tuned!

Hope you liked it. 🙂

  1. 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
