Aman-Malhotra / Volume_Flutter

Now you can change android volumes in Flutter. You can change MEDIA volume, NOTIFICATION volume, RING Volume, VOICE CALL Volume, ALARM Volume and SYSTEM Volume. This is exclusively for android right now because I don't have max to do the IOS coding and I don't have experience in IOS coding as well. Pull requests for IOS Implementation are welcome.

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.
