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

> 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.

    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);
