Let me investigate what this code is supposed to do ...

Yeah this one's super weird. AFAICT, there is no reason then(THIS) should have to return something. I think the error,
This function has a return type of 'Future<Map<String, dynamic>>', but doesn't
end with a return statement • packages/flutter_tools/lib/src/run_hot.dart:443:13
is saying that one path returns a Future<Map<String, dynamic>>, and another pass doesn't return anything, and those two paths then don't match any consistent return type. This return value isn't used anywhere, right?

The whenComplete triggers off of the returned future, or the immediate result of return null. in this case it should be:
if ((pauseEvent != null) && pauseEvent.isPauseEvent) {
return view.uiIsolate.resume();
}
return null;
It's the best time of the year! |
