Instantiation

1. The ApiVideoPlayerController

To use a video player, you must instantiate a new controller.

The ApiVideoPlayerController parameters are:

Parameter	Mandatory	Type	Description
videoOptions	Yes	VideoOptions	Options from the video you want to display inside the current video player
autoplay	No (default false)	bool	Whether you want your video to be automatically played when it's ready or not
onReady	No	VoidCallback	A callback called when the video is ready to be played
onPlay	No	VoidCallback	A callback called when the video is played
onPause	No	VoidCallback	A callback called when the video is paused
onEnd	No	VoidCallback	A callback called when the video has ended
onError	No	Function(Object)	A callback called when an error occured

Once instantiated, you need to initialize the controller by calling its initialize() method.

final ApiVideoPlayerController controller = ApiVideoPlayerController(
  videoOptions: VideoOptions(videoId: 'VIDEO_ID'), // `VIDEO_ID` is the video id or the live stream id
  // For private video: VideoOptions(videoId: "YOUR_VIDEO_ID", token: "YOUR_PRIVATE_TOKEN")
);

await controller.initialize();

See the sample application below for more details.

2. The ApiVideoPlayer

A Widget that displays the video and its controls.

The ApiVideoPlayer constructor takes 3 parameters:

Parameter	Mandatory	Type	Description
controller	Yes	ApiVideoPlayerController	The controller that controls a video player
fit	No (default BoxFit.contain)	BoxFit	How the player should be inscribed into its box.
style	No (default api.video style)	PlayerStyle	Allows you to customize the video player's colors, shapes,...
child	No (default api.video overlay)	Widget	Replace api.video overlay by your own implementation.


final ApiVideoPlayerController controller = ApiVideoPlayerController(
  videoOptions: VideoOptions(videoId: 'VIDEO_ID'),
  // For private video: VideoOptions(videoId: "YOUR_VIDEO_ID", token: "YOUR_PRIVATE_TOKEN")
);

await controller.initialize();

Widget build(BuildContext context) {
  return ApiVideoPlayer(
    controller: controller,
  );
}

Methods

Once the ApiVideoPlayerController has been instantiated, you can control the player it has been assigned to with its methods:

Method	Description
play()	Play the video
pause()	Pause the video
seek(Duration offset)	Add/substract the given Duration from the current time
setVolume(double volume)	Change the audio volume to the given value. From 0 to 1 (0 = muted, 1 = 100%)
setIsMuted(bool isMuted)	Mute/unmute the video
setAutoplay(bool autoplay)	Define if the video should start playing as soon as it is loaded
setIsLooping(bool isLooping)	Define if the video should be played in loop
setCurrentTime(Duration currentTime)	Set the current playback time
setVideoOptions(VideoOptions videoOptions)	Set the video options

Example:


final ApiVideoPlayerController controller = ApiVideoPlayerController(
  videoOptions: VideoOptions(videoId: 'VIDEO_ID'),
  // For private video: VideoOptions(videoId: "YOUR_VIDEO_ID", token: "YOUR_PRIVATE_TOKEN")
);

await controller.initialize();

controller.play(); // Play the video

Properties

Once the ApiVideoPlayerController has been instantiated, you can access the video player's properties:

Property	Type	Description
isCreated	Future<bool>	Check if the player has been created
isPlaying	Future<bool>	Check whether the video is playing
videoOptions	Future<VideoOptions>	Retrieve the current video options
currentTime	Future<Duration>	Retrieve the current playback time of the video
duration	Future<Duration>	Retrieve the duration of the video
autoplay	Future<bool>	Check whether the video is autoplayed
isMuted	Future<bool>	Check whether the video is muted
isLooping	Future<bool>	Check whether the video is in loop mode
volume	Future<double>	Retrieve the current volume
videoSize	Future<Size?>	Retrieve the current video size

Example:


final ApiVideoPlayerController controller = ApiVideoPlayerController(
  videoOptions: VideoOptions(videoId: 'VIDEO_ID'),
  // For private video: VideoOptions(videoId: "YOUR_VIDEO_ID", token: "YOUR_PRIVATE_TOKEN")
);

await controller.initialize();

final bool isMuted = await controller.isMuted;

Events listener

Add a new event listener: Method 1

When you instantiate a new ApiVideoPlayerController, you can bind callbacks to some events:


final ApiVideoPlayerController controller = ApiVideoPlayerController(
  videoOptions: VideoOptions(videoId: 'VIDEO_ID'),
  // For private video: VideoOptions(videoId: "YOUR_VIDEO_ID", token: "YOUR_PRIVATE_TOKEN")
  onPlay: () => print('PLAY'),
  onPause: () => print('PAUSE'),
);

Add a new event listener: Method 2

Once the ApiVideoPlayerController has been instantiated, you can bind callbacks to some events:


final ApiVideoPlayerController controller = ApiVideoPlayerController(
  videoOptions: VideoOptions(videoId: 'VIDEO_ID'),
  // For private video: VideoOptions(videoId: "YOUR_VIDEO_ID", token: "YOUR_PRIVATE_TOKEN")
);

await controller.initialize();

final ApiVideoPlayerControllerEventsListener eventsListener =
ApiVideoPlayerControllerEventsListener(
  onPlay: () => print('PLAY'),
);

controller.addListener(eventsListener);

Event	Type	Description
onReady	VoidCallback	A callback called when the video is ready to be played
onPlay	VoidCallback	A callback called when the video is played
onPause	VoidCallback	A callback called when the video is paused
onEnd	VoidCallback	A callback called when the video has ended
onError	Function(Object)	A callback called when an error occured

Remove an event listener

To remove an event listener, you need to call the controller's removeListener method.


final ApiVideoPlayerController controller = ApiVideoPlayerController(
  videoOptions: VideoOptions(videoId: 'VIDEO_ID'),
  // For private video: VideoOptions(videoId: "YOUR_VIDEO_ID", token: "YOUR_PRIVATE_TOKEN")
);

await controller.initialize();

final ApiVideoPlayerControllerEventsListener eventsListener =
ApiVideoPlayerControllerEventsListener(
  onPlay: () => print('PLAY'),
);

controller.removeListener(eventsListener);

class MyApp extends StatefulWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  final ApiVideoPlayerController _controller = ApiVideoPlayerController(
    videoOptions: VideoOptions(videoId: 'VIDEO_ID'),
    // For private video: VideoOptions(videoId: "YOUR_VIDEO_ID", token: "YOUR_PRIVATE_TOKEN")
    onPlay: () => print('PLAY'),
  );
  String _duration = 'Get duration';

  @override
  void initState() {
    super.initState();
    _controller.initialize();
    _controller.addListener(
      ApiVideoPlayerControllerEventsListener(
        onPause: () => print('PAUSE'),
      ),
    );
  }

  void _getDuration() async {
    final Duration duration = await _controller.duration;
    setState(() {
      _duration = 'Duration: $duration';
    });
  }

  void _muteVideo() {
    _controller.setIsMuted(true);
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Builder(builder: (context) {
        return Scaffold(
          body: Center(
            child: Column(
              children: <Widget>[
                SizedBox(
                  width: 400.0,
                  height: 300.0,
                  child: ApiVideoPlayer(
                    controller: _controller,
                  ),
                ),
                IconButton(
                  icon: const Icon(Icons.volume_off),
                  onPressed: _muteVideo,
                ),
                TextButton(
                  onPressed: _getDuration,
                  child: Text(
                    _duration,
                    textAlign: TextAlign.center,
                  ),
                ),
              ],

          ),
