As a result, React Native is an effective tool for developing high-performance mobile apps that maintain a consistent user experience across various devices through its exclusive component lifecycle.

There are numerous methods available in React Native for taking screenshots. A few integrated APIs in React Native let you record the active screen or particular app views. These APIs allow you to programmatically record the graphical user interface (UI) of your app, which may then be used for a variety of things including documentation, user feedback, or sharing.

There are third-party libraries that offer further capabilities and customization choices in addition to the built-in APIs for taking screenshots. These libraries can provide additional functionalities like capturing specific elements, adding annotations or watermarks, or even manipulating the captured screenshots.

Let’s move on to the next phase, which is adding screen capture functionality to React Native app development, now that we have a firm understanding of React Native and its screen capture features.  

Implementing Screen Capture Functionality in React Native

You must install the required packages and libraries in order to include screen capture capability in your React Native application. These packages will provide the tools and APIs required to capture screenshots programmatically. Follow the steps below to get started:

Step 1: Install Dependencies:

Ensure that you have a React Native project set up before starting to write code. Go to the project’s root directory after launching your project in a terminal. Run the subsequent command to install the required dependencies after that:

npm install react-native-view-shot

The react-native-view-shot library is a popular choice for capturing screenshots in React Native. It provides a simple and straightforward API for taking screenshots of specific views or the entire screen.

Step 2: Link the Library (For React Native versions below 0.60):

You must link the library to your project if you’re using React Native 0.59 or earlier. Run the following command in your project’s root directory:

react-native link react-native-view-shot

“Note: If you’re using React Native version 0.60 or above, the library should be automatically linked to your project.”

Step 3: Implementing the Screen Capture Functionality:

You may move forward with adding the screen capture capability to your React Native project now that the dependencies have been installed. Take these actions:

a. Import the necessary modules and components:

In the file where you want to capture the screenshot, import the following modules:

The captureRef function from react-native-view-shot is the key API we’ll use to capture screenshots.

b. Request necessary permissions (Android only):

On Android, you’ll need to request the necessary permissions for capturing screenshots. Add the following code before the component definition:

This code requests the necessary storage permission from the user.If the permit is denied, the proper course of action can be followed.

c. Create a reference for the view to be captured:

Give the view you want to capture a reference in the render method of your component. For instance:

In this illustration, the view containing the content you wish to capture has the reference “this.captureViewRef” attached to it. Replace the comment with the precise information you wish to show in the screenshot..

d. Implement the screenshot capture function:

Create a function that will be triggered to capture the screenshot. For example:

The screenshot of the view referred to by ‘this.captureViewRef’ is taken using the ‘captureRef’ method in this function. The ‘quality’ option establishes the level of picture compression, while the ‘format’ option defines the preferred image format (such as ‘jpg’ or ‘png’).

The function can be changed to meet your own needs, such as saving the screenshot to the device, sharing it, or processing it further.

Step 4: Trigger the Screenshot Capture:

You can call the “captureScreenshot” function from a button press, a menu item, or any other pertinent user interaction within your app to start taking screenshots. For instance:

javascript

<Button onPress={this.captureScreenshot} title=”Capture Screenshot” />

The ‘captureScreenshot’ function will be invoked and the screenshot will be taken when the button is pressed.

Congratulations! You used the ‘react-native-view-shot’ library to implement the screen capture feature in your React Native app successfully. You can now capture screenshots of specific views or the entire screen, opening up endless possibilities for utilizing and sharing visual content within your app.
