A Flutter plugin for iOS and Android for playing back video on a Widget surface.
Note: This plugin is still under development, and some APIs might not be available yet. Feedback welcome and Pull Requests are most welcome!
First, add video_player as a dependency in your pubspec.yaml file.
Warning: The video player is not functional on iOS simulators. An iOS device must be used during development/testing.
Add the following entry to your Info.plist file, located in <project root>/ios/Runner/Info.plist:
<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>This entry allows your app to access video files by URL.
Ensure the following permission is present in your Android Manifest file, located in <project root>/android/app/src/main/AndroidManifest.xml:
<uses-permission android:name="android.permission.INTERNET"/>The Flutter project template adds it, so it may already be there.
This plugin compiles for the web platform since version 0.10.5, in recent enough versions of Flutter (>=1.12.13+hotfix.4).
The Web platform does not suppport
dart:io, so attempts to create aVideoPlayerController.filewill throw anUnimplementedError.
Different web browsers may have different video-playback capabilities (supported formats, autoplay...). Check package:video_player_web for more web-specific information.
- On iOS, the backing player is AVPlayer. The supported formats vary depending on the version of iOS, AVURLAsset class has audiovisualTypes that you can query for supported av formats.
- On Android, the backing player is ExoPlayer, please refer here for list of supported formats.
- On Web, available formats depend on your users' browsers (vendor and version). Check package:video_player_web for more specific information.
