Play music/audio stored in assets files directly from Flutter. Compatible with Android & iOS.

assets_audio_player

Play music/audio stored in assets files directly from Flutter.

No needed to copy songs to a media cache, with assets_audio_player you can open them directly from the assets.

1. Create an audio directory in your assets (not necessary named "audios")
2. Declare it inside your pubspec.yaml

flutter:
  assets:
    - assets/audios/

Getting Started

final assetsAudioPlayer = AssetsAudioPlayer();

assetsAudioPlayer.open(
    "assets/audios/song1.mp3",
);

assetsAudioPlayer.playOrPause();
assetsAudioPlayer.play();
assetsAudioPlayer.pause();

assetsAudioPlayer.seek(Duration to);

assetsAudioPlayer.stop();

Listeners

All listeners exposes Streams Using RxDart, AssetsAudioPlayer exposes some listeners as ValueObservable (Observable that provides synchronous access to the last emitted item);

Current song

//The current playing audio, filled with the total song duration
assetsAudioPlayer.current //ValueObservable<PlayingAudio>

//Retrieve directly the current played asset
final PlayingAudio playing = assetsAudioPlayer.current.value;

//Listen to the current playing song
assetsAudioPlayer.current.listen((playingAudio){
    final asset = playingAudio.assetAudio;
    final songDuration = playingAudio.duration;
})

Current song duration

//Listen to the current playing song
final duration = assetsAudioPlayer.current.value.duration;

Current position (in seconds)

assetsAudioPlayer.currentPosition //ValueObservable<Duration>

//retrieve directly the current song position
final Duration position = assetsAudioPlayer.currentPosition.value;

return StreamBuilder(
    stream: assetsAudioPlayer.currentPosition,
    builder: (context, asyncSnapshot) {
        final Duration duration = asyncSnapshot.data;
        return Text(duration.toString());  
    }),

IsPlaying

boolean observable representing the current mediaplayer playing state

assetsAudioPlayer.isPlaying // ValueObservable<bool>

//retrieve directly the current player state
final bool playing = assetsAudioPlayer.isPlaying.value;

//will follow the AssetsAudioPlayer playing state
return StreamBuilder(
    stream: assetsAudioPlayer.isPlaying,
    builder: (context, asyncSnapshot) {
        final bool isPlaying = asyncSnapshot.data;
        return Text(isPlaying ? "Pause" : "Play");  
    }),

Finished

Called when the current song has finished to play

assetsAudioPlayer.finished //ValueObservable<bool>

assetsAudioPlayer.finished.listen((finished){
    
})

Looping

final bool isLooping = assetsAudioPlayer.loop; //true / false

assetsAudioPlayer.loop = true; //set loop as true

assetsAudioPlayer.isLooping.listen((loop){
    //listen to loop
})

assetsAudioPlayer.toggleLoop(); //toggle the value of looping
