How to add Share button in React Native ?

React Native is an open-source UI software framework created by Meta Platforms, Inc. It is used to develop applications for Android, Android TV, iOS, macOS, tvOS, Web, Windows, and UWP by enabling developers to use the React framework along with native platform capabilities.

In this article, we will be learning how we can add a share button in react native.

Creating React Native App: 

Step 1: We'll be using expo to create the react native app. Install expo-cli using the below command in the terminal.

npm install -g expo-cli

import { Share, View, Button, Text } from "react-native"; 

const GfGApp = () => {

		try { 
			await Share.share({ 
				message: 
					'This is the demo text', 
			}); 
		} catch (error) { 
			alert(error.message); 
		} 
	}; 
	return ( 
		<View style={{ marginTop: 80 }}> 
			<Text style={{ fontSize: 18 }}> 
				GeeksforGeeks React Native Share</Text> 
			<Button onPress={shareData} title="Share" /> 
		</View> 
	); 
}; 

export default GfGApp;
