Refresh Previous Screen after Going Back in React Navigation

Refresh Previous Screen after Going Back in React Navigation

This is an Example to Refresh the Previous Screen after Going Back to the old Screen in React Native using React Navigation. If you are familiar with the navigation in React Native then I hope you very well know React Navigation. We have also used the same navigator for this example.

While working with multiple screens we usually switch between screens and sometimes wants to refresh the previous screen as the result set should change. If we talk about React Navigation it does not provide the default refresh facility as in most of the cases we do not want to rerender the view. So we have to add some extra things to refresh the previous screens while going back.

To refresh the previous screen when going back

As a JavaScript developer, we very well know about the listeners. In this case, we will also use a listener called didFocus to find the current state of the Screen/ Activity.

To apply didFocus listener:

To remove the listener:

In this example, we will create 2 Screens FirstPage and SecondPage and will make a count on both the screens to see whether it is refreshing or not. If we run the application without the didFocus listener we have no way to reset the counter when coming back to FirstPage so counter will increase as we are unable to refresh the screen but in other condition when we apply the didFocus listener we can reset the counter or basically we can say that we can refresh the screen. So Let’s get Started with example.

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
This 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

Run the following commands

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

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.


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


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


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).
