Example to Call Functions of Other Class From Current Class in React Native

This is an Example to Call Functions of Other Class From Current Class in React Native. This can be usually seen in object-oriented languages like Java; Where we make an object of the other class and call the function of it. In the case of React Native, you can also do the same by making an object of a class. You can also pass the arguments if you want.

To call the function from OtherClass


In this example of Calling Functions of Other Class From Current Class, we will make an OtherClass and will define two functions with and without arguments and after that, we will call this functions from Our default class.

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.

Open App.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).


This is how you can call the function of other class from the current class. 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!
