A Flutter plugin for iOS and Android for sharing text, image, video and file with system ui.
First, add share_extend as a dependency in your pubspec.yaml file.
dependencies:
share_extend: "^2.1.0"
Add the following key to your info.plist file, located in <project root>/ios/Runner/Info.plist for saving shared images to photo library.
<key>NSPhotoLibraryAddUsageDescription</key>
<string>describe why your app needs access to write photo library</string>
If your project needs read and write permissions for sharing external storage file, please add the following permissions to your AndroidManifest.xml, located in <project root>/android/app/src/main/AndroidManifest.xml
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

//share video
