Flutter plugin for playing or streaming YouTube videos inline using the official iFrame Player API. The package exposes almost all the API provided by iFrame Player API. So, it's 100% customizable.

Note: This package only provides default youtube web player's skin. If you need Youtube Android player like player with gesture support, use youtube_player_flutter instead. youtube_player_flutter also uses this package as dependency. (Migration Pending)

Supported Platforms:

  • Android
  • iOS

Salient Features

  • Inline Playback
  • Supports captions
  • No need for API Key
  • Supports custom controls
  • Retrieves video meta data
  • Supports Live Stream videos
  • Supports changing playback rate
  • Support for both Android and iOS
  • Adapts to quality as per the bandwidth
  • Exposes builders for building custom controls
  • Playlist Support (Both custom and Youtube's playlist)

For Web, Flutter's HtmlElementView. For Android & iOS, the package uses flutter_inappwebview under-the-hood.

If your app uses services workers, you may need add additional configuration on the app startup code, in order to ensure that the web view behaviour don't get unstable. To do so, please refer to the flutter_inappwebview documentation.

Since flutter_inappwebview relies on Flutter's mechanism for embedding Android and iOS views, this plugin might share some known issues tagged with the platform-views label.

Requirements

  • Android: minSdkVersion 17 and add support for androidx (see AndroidX Migration)
  • iOS: --ios-language swift, Xcode version >= 11
  • Web: None

Follow the guide here for complete Android setup

Note: Although the minimum to be set is 17, the player won't play on device with API < 20 (19 if Hybrid Composition is enabled). For API < 20 devices, you might want to forward the video to be played using YouTube app instead, using packages like url_launcher or android_intent.

Using the player

YoutubePlayerController _controller = YoutubePlayerController(
    initialVideoId: 'K18cpp_-gP8',
    params: YoutubePlayerParams(
        playlist: ['nPt8bK2gbaU', 'gQDByCdjUXw'], // Defining custom playlist
        startAt: Duration(seconds: 30),
        showControls: true,
        showFullscreenButton: true,
    ),
);

YoutubePlayerIFrame(
    controller: _controller,
    aspectRatio: 16 / 9,
),

-------------- OR --------------

YoutubePlayerControllerProvider( // Provides controller to all the widget below it.
  controller: _controller,
  child: YoutubePlayerIFrame(
    aspectRatio: 16 / 9,
  ),
);

// Access the controller as: `YoutubePlayerControllerProvider.of(context)` or `controller.ytController`.

Want to customize the player?

The package provides YoutubeValueBuilder, which can be used to create any custom controls.

For example, let's create a custom play pause button.

YoutubeValueBuilder(
   controller: _controller, // This can be omitted, if using `YoutubePlayerControllerProvider`
   builder: (context, value) {
      return IconButton(
         icon: Icon( 
                  value.playerState == PlayerState.playing
                    ? Icons.pause
                    : Icons.play_arrow,
         ),
         onPressed: value.isReady
            ? () {
                  value.playerState == PlayerState.playing
                    ? context.ytController.pause()
                    : context.ytController.play();
                 }
            : null,
      );
   },
);
