Example

To use this plugin :

audioPlayer.pause();

audioPlayer.stop();

Status and current position

The dart part of the plugin listen for platform calls :

//...
_positionSubscription = audioPlayer.onAudioPositionChanged.listen(
  (p) => setState(() => position = p)
);

_audioPlayerStateSubscription = audioPlayer.onPlayerStateChanged.listen((s) {
  if (s == AudioPlayerState.PLAYING) {
    setState(() => duration = audioPlayer.duration);
  } else if (s == AudioPlayerState.STOPPED) {
    onComplete();
    setState(() {
      position = duration;
    });
  }
}, onError: (msg) {
  setState(() {
    playerState = PlayerState.stopped;
    duration = new Duration(seconds: 0);
    position = new Duration(seconds: 0);
  });
});

Do not forget to cancel all the subscriptions when the widget is disposed.
