Hot restart does not set flavor

[Tetr4]

I have set a build flavor (--flavor) in my run configuration, which works fine with a normal build.

However when performing a hot restart it is not set anymore. This used to work previously.

To test this:

import 'package:flutter/services.dart';
import 'package:flutter/widgets.dart';

void main() {
  debugPrint(appFlavor); // This prints null on hot restart
}
