Why is source info missing in flutter error

I got the following error in the console while running my app:

flutter: type '() => Null' is not a subtype of type '(dynamic) => FutureOr<dynamic>' of 'f'

Unfortunately it doesn't tell me which code actually caused this error? Why is flutter missing some more information in the output?

Visual Studio Code 1.28.2
Flutter 0.9.4
Dart VM version: 2.0.0

Since you didn't put any code, so as far as I can tell, you are using () which is returning Null, and you were supposed to use (dynamic value) returning Future in your method declaration somewhere in your code.
