Сначала необходимо инициализировать webOnlyScheduleFrameCallback

1 голос
/ 07 апреля 2020

Я пытаюсь преобразовать свое приложение FLutter во Flutter Web, поэтому я преобразую void main => runApp(Myapp()); в 

void main() async {
    WidgetsFlutterBinding.ensureInitialized();
    runApp(MyApp());

}

Но я запускаю flutter run -d chrome, у меня есть белая страница и эта ошибка : 

Uncaught (in promise) Error: Exception: webOnlyScheduleFrameCallback must be initialized first.
    at Object.throw_ [as throw] (errors.dart:196)
