React Native Example to Take Screenshot Programmatically

Here is an Example to Take Screenshot Programmatically in React Native. To take Screenshot of your screen we have an inbuilt Screenshot option provided by mobile manufacturers but you can also make this in your own Application too. To take a Screenshot we will use a very good library called react-native-view-shot. Which provides captureScreen API which is very easy to use.

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 Dependency

To use captureScreen we need to install react-native-view-shot package.

To install this open the terminal and jump into your project

Run the following command

This command will copy all the dependencies into your node_module directory, You can find the directory in node_module the directory named react-native-view-shot.
