Флаттер: необработанное исключение: ServicesBinding.defaultBinaryMessenger

Question

[ERROR:flutter/lib/ui/ui_dart_state.cc(157)] Unhandled Exception: ServicesBinding.defaultBinaryMessenger was accessed before the binding was initialized.
E/flutter (10075): If you're running an application and need to access the binary messenger before `runApp()` has been called (for example, during plugin initialization), then you need to explicitly call the `WidgetsFlutterBinding.ensureInitialized()` first.
E/flutter (10075): If you're running a test, you can call the `TestWidgetsFlutterBinding.ensureInitialized()` as the first line in your test's `main()` method to initialize the binding.

void main(){
  WidgetsFlutterBinding.ensureInitialized();
  SystemChrome.setPreferredOrientations([DeviceOrientation.portraitUp]);
  runApp(new MyApp());
}

Недавно я обновил свои версии, у меня были проблемы даже с AndroidX, мне удалось выйти из этого хаоса, но теперь у меня есть этот, в некоторых других потоках они решаются добавлением WidgetsFlutterBinding.ensureInitialized () линия; но в моем случае нет, может быть, что в моем главном представлении отсутствует какой-либо метод?

Шаг, чтобы оставить также фрагмент кода из другого представления, является StatefulWidget

  @override
  void initState() {
    validarUsrPrimeraVez();

    super.initState();

  }

  Future<List<Producto>> getPipeteodeCesar() async {
    return await ClientDatabaseProvider.db.getAllProductos();
  }

  @override
  Widget build(BuildContext context) {
    final screenWidth = MediaQuery.of(context).size.width;
    final screenHeight = MediaQuery.of(context).size.height;

    return
      Scaffold(
        body: FutureBuilder<List<Producto>>(
            initialData: nombre,
            future: ClientDatabaseProvider.db.getAllProductos(),
            builder: (BuildContext context,AsyncSnapshot<List<Producto>> snapshot) {
              if(bandera) { // 00
                return SafeArea(
                  child: Stack(
                    children: <Widget>[
                      _containerBackground(context,screenWidth,screenHeight),
                      _containerLogo(screenWidth,screenHeight),
                      _OneButton(context),
                    ],
                  ),
                );
              }else{
                return SafeArea(
                  child: Stack(
                    children: <Widget>[
                      _containerBackground(context,screenWidth,screenHeight),
                      _containerLogo(screenWidth,screenHeight),
                      _botones(context),
                    ],
                  ),
                );
              }
            }
        ),
      );
  }
