Quick Clean Cache

1. Open android studio Tools->Flutter->Clean
2. Go to File -> Invalidate Caches / Restart
3. Or open terminal run "flutter clean"
4. Remove pubspec.lock
5. Double check the Flutter SDK Path config correcty - https://tppr.me/qn6dP

}

Future<Duration> _runCPUBoundTask() async {
    var startTime = DateTime.now();
    print('Starting ...');
