如何解决错误状态：尝试读取在创建其值期间抛出的提供程序在创建 Future<List<Place>> ================================================ ============当我这样导航时没问题MultiProvider -> MaterialApp -> DesiredScreen================================================ ============但

我知道很多人问这个问题，但我没有找到任何答案，所以这有点不同

我正面临这个错误。当我直接从主页调用 Desired Screen 时它工作正常，但是当我从另一个屏幕导航 DesiredScreen 时，它显示此错误。我用地图给你解释

================================================ ============

当我这样导航时没问题

MultiProvider -> MaterialApp -> DesiredScreen

================================================ ============

但是当我浏览它时，它显示了这个 BadState 错误

MultiProvider -> MaterialApp -> HomePage -> DesiredScreen

================================================ ============

更新的问题

当我把条件放在主类小部件中时

count == 1 ? DesiredScreen() : HomePage()

它显示此错误，但如果我从其他屏幕导航到 DesiredScreen，它不会显示 错误

================================================ ============

代码

Widget build(BuildContext context) {
    return MultiProvider(
      providers: [
        FutureProvider(
          create: (_) => locatorService.getLocation(),initialData: null,),FutureProvider(
          initialData: null,create: (_) {
            ImageConfiguration imageConfiguration =
                createLocalImageConfiguration(context);
            return BitmapDescriptor.fromAssetimage(
                imageConfiguration,'assets/images/fire.png');
          },ProxyProvider2<Position,BitmapDescriptor,Future<List<Place>>>(
            update: (_,position,icon,places) {
          return (position != null)
              ? placeService.getPlaces(
                  position.latitude,position.longitude,icon)
              : null;
        })
      ],child: MaterialApp(
        debugShowCheckedModeBanner: false,theme: ThemeData(
          primaryColor: Colors.blueAccent,home: DesiredScreen(),);
