FlutterSoundPlayer class

A Player is an object that can playback from various sources.

Using a player is very simple :

  1. Create a new FlutterSoundPlayer

  2. Open it with openAudioSession()

  3. Start your playback with startPlayer().

  4. Use the various verbs (optional):

  5. Stop your player : stopPlayer()

  6. Release your player when you have finished with it : closeAudioSession(). This verb will call stopPlayer() if necessary.

Constructors

FlutterSoundPlayer({Level logLevel = Level.debug, bool voiceProcessing = false})
Instanciate a new Flutter Sound player. The optional paramater Level logLevel specify the Logger Level you are interested by. The optional parameter bool voiceProcessing is used to activate the VoiceProcessingIO AudioUnit (only for iOS)

Methods

closePlayer() → Future<void>
Close an open session.
dispositionStream() → Stream<PlaybackDisposition>?
Provides a stream of dispositions which provide updated position and duration as the audio is played.
feedFromStream(Uint8List buffer) → Future<void>
Used when you want to play live PCM data synchronously.
getPlayerState() → Future<PlayerState>
Query the current state to the Tau Core layer.
getProgress() → Future<Map<String, Duration>>
Get the current progress of a playback.
getResourcePath() → Future<String?>
Get the resource path.
isDecoderSupported(Codec codec) → Future<bool>
Returns true if the specified decoder is supported by flutter_sound on this platform
isOpen() → bool
Return true if the Player has been open
log(Level logLevel, String msg) → void
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
openPlayer({dynamic isBGService = false}) → Future<FlutterSoundPlayer?>
Open the Player.
pausePlayer() → Future<void>
Pause the current playback.
resumePlayer() → Future<void>
Resume the current playback.
seekToPlayer(Duration duration) → Future<void>
To seek to a new location.
setLogLevel(Level aLevel) → void
Used if the App wants to dynamically change the Log Level. Seldom used. Most of the time the Log Level is specified during the constructor.
setSpeed(double speed) → Future<void>
Change the playback speed
setSubscriptionDuration(Duration duration) → Future<void>
Specify the callbacks frenquency, before calling startPlayer.
setVolume(double volume) → Future<void>
Change the output volume
setVolumePan(double volume, double pan) → Future<void>
startPlayer({String? fromURI, Uint8List? fromDataBuffer, Codec codec = Codec.aacADTS, int sampleRate = 16000, int numChannels = 1, TWhenFinished? whenFinished}) → Future<Duration?>
Used to play a sound.
startPlayerFromMic({int sampleRate = 44000, int numChannels = 1, int bufferSize = 8192, dynamic enableVoiceProcessing = false}) → Future<void>
Starts the Microphone and plays what is recorded.
startPlayerFromStream({Codec codec = Codec.pcm16, int numChannels = 1, int sampleRate = 16000, int bufferSize = 8192, TWhenFinished? whenFinished}) → Future<void>
Used to play something from a Dart stream
stopPlayer() → Future<void>
Stop a playback.
toString() → String
A string representation of this object.
