Job scheduler breaks on release mode

E/flutter ( 8931): Receiver: null
E/flutter ( 8931): Tried calling: call()
E/flutter ( 8931): #0      Object.noSuchMethod (dart:core/runtime/libobject_patch.dart:46)
E/flutter ( 8931): #1      _startIsolate.<anonymous closure> (dart:isolate/runtime/libisolate_patch.dart:279)
E/flutter ( 8931): #2      _RawReceivePortImpl._handleMessage (dart:isolate/runtime/libisolate_patch.dart:165)

It only occurs on release builds. No problem with development builds. The application must be closed.

Moving function into main.dart fixes the problem.

Thanks for the detailed problem description. This is may be happening due to unused Code Stripping Optimizations of the Dart Compiler on release builds. Does the problem also occur if you reference the scheduled function from somewhere else in your code?
