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(() {});
