What is SharePlus?
SharePlus is a popular Flutter package that provides a simple and intuitive way to share content from your app. It supports multiple platforms, including Android, iOS, and desktop, making it an ideal solution for cross-platform development. With SharePlus, you can share text, images, files, and even prefill email subjects and bodies.
Why Use SharePlus?
- Easy to implement: SharePlus is incredibly easy to use, even for developers new to Flutter. The package provides a simple API that can be integrated into your app in no time.
- Cross-platform compatibility: SharePlus supports multiple platforms, ensuring that your app provides a seamless sharing experience regardless of the device or operating system.
- Customizable: SharePlus allows you to customize the share sheet and email prefills to fit your app’s unique needs and branding.
- Lightweight: SharePlus is a lightweight package that won’t bloat your app or affect its performance.
Setting Up SharePlus in Your Flutter App
To get started with SharePlus, you’ll need to add the package to your Flutter project. Follow these steps:
flutter pub add share_plus
(add SharePlus to your pubspec.yaml file)flutter pub get
(get the package)- Import the package in your Dart file:
import 'package:share_plus/share_plus.dart';
Opening the Share Sheet with SharePlus
Now that you’ve set up SharePlus, let’s explore how to open the share sheet and prefill email. The share sheet is a system-provided UI that allows users to select from a list of installed apps that can handle the shared content.
Future _shareText() async {
await Share.share('Hello, world!');
}
In the code above, we’re using the Share.share()
method to open the share sheet with a prefilled text message. You can replace the text with any content you’d like to share.
Prefilling Email with SharePlus
Prefilling email subjects and bodies is a powerful feature that enhances the user experience. With SharePlus, you can prefill email fields using the Share.shareX()
method.
Future _shareEmail() async {
await Share.shareX(
'mailto:user@example.com?subject=Hello+from+Flutter&body=Check+out+this+awesome+app!',
subject: 'Hello from Flutter',
text: 'Check out this awesome app!',
);
}
In this example, we’re using the Share.shareX()
method to prefill the email subject and body. The mailto:
protocol is used to specify the email address, and the subject
and body
parameters are used to prefill the corresponding fields.
Sharing Files with SharePlus
SharePlus also supports sharing files, which can be useful for apps that need to share images, documents, or other types of files.
Future _shareFile() async {
final directory = await getApplicationDocumentsDirectory();
final file = File('${directory.path}/example.txt');
await file.writeAsString('Hello, world!');
await Share.shareXFiles(
files: [file.path],
text: 'Check out this file!',
);
}
In this example, we’re creating a file using the getApplicationDocumentsDirectory()
method and writing a string to it. We then use the Share.shareXFiles()
method to share the file with a prefilled text message.
Customizing the Share Sheet with SharePlus
SharePlus provides several options for customizing the share sheet to fit your app’s needs. You can customize the share sheet title, subject, and text, as well as specify the apps that should be shown in the share sheet.
Future _shareCustom() async {
await Share.share(
'Hello, world!',
subject: 'Custom Share Sheet',
sharePositionOrigin: Rectangle.fromLTRB(0, 0, 0, 0),
shareApplicationPackage: 'com.example.app',
);
}
In this example, we’re customizing the share sheet title, subject, and position origin. We’re also specifying the app package that should be shown in the share sheet.
Troubleshooting SharePlus Issues
If you encounter issues while using SharePlus, here are some troubleshooting tips:
- Check the SharePlus version: Ensure that you’re using the latest version of SharePlus. You can check the version by running
flutter pub outdated
