volume

Controll Volume in Android programatically. No IOS Implementation yet . Pull Request for ios implementation are welcome.

Streams

AudioManager.STREAM_VOICE_CALL       -> Controll IN CALL Volume
AudioManager.STREAM_SYSTEM           -> Controll SYSTEM Volume
AudioManager.STREAM_RING             -> Controll RINGER Volume
AudioManager.STREAM_MUSIC            -> Controll MEDIA Volume
AudioManager.STREAM_ALARM            -> Controll ALARM Volume
AudioManager.STREAM_NOTIFICATION     -> Controll NOTIFICATION Volume

Show and Hide System UI

ShowVolumeUI.SHOW (DEFAULT)          -> Show system volume UI while changing volume 
ShowVolumeUI.HIDE                    -> Do not show system volume UI while changing volume 

Functions and getters

Volume Buttons will affect this volume when in app

await Volume.controlVolume(AudioManager audioManager); // pass any stream as parameter

Returns maximum possible volume in integers

await Volume.getMaxVol; // returns an integer

Returns current volume level in integers

await Volume.getVol;// returns an integer

Set volume for the stream passed to controlVolume() function

await Volume.setVol(int i, {ShowVolumeUI showVolumeUI});

Max value of i is less than or equal to Volume.getMaxVol.

showVolumeUI is optional parameter which defaults to ShowVolumeUI.SHOW.

Usage

class _MyAppState extends State<MyApp> {
  int maxVol, currentVol;

  @override
  void initState() {
    super.initState();
    audioManager = AudioManager.STREAM_SYSTEM;
    initAudioStreamType();
    updateVolumes();
  }

  Future<void> initAudioStreamType() async {
    await Volume.controlVolume(AudioManager.STREAM_SYSTEM);
  }

  updateVolumes() async {
    // get Max Volume
    maxVol = await Volume.getMaxVol;
    // get Current Volume
    currentVol = await Volume.getVol;
    setState(() {});
  }

  setVol(int i) async {
    await Volume.setVol(i, showVolumeUI: ShowVolumeUI.SHOW);
    // or 
    // await Volume.setVol(i, showVolumeUI: ShowVolumeUI.HIDE);
  }
  // To implement the volume Up and volume Down button press programatically.
