错误:颤振/lib/ui/ui\u省道\u状态。cc(148)未处理的异常

在应用程序启动时获取此错误。最初我认为这是一个迁移到Android的问题,做了所有的步骤迁移到androidx支持库,但没有用。

  1. 在此处发布了Github问题

无法调试,因为我在主函数第一行的断点命中之前得到了这个错误。

错误

请检查请求类型是GET还是POST。如果您调用获取请求作为发布请求,它会显示此错误。如果请求类型正确,请检查您的JSON响应是否为JSON格式。我希望它能有所帮助。

这是一个类型不匹配错误。请确保返回类型与变量类型相同

当我将Flutter从1.0.3迁移到1.2.1时,我也遇到了类似的问题。我发现的问题与在val main方法上定义的参数有关。调用main时,这些参数永远不会传递。要解决此问题,您可以删除这些参数,并对正在使用它的其他地方进行以下更改。

void main() async {
.
.
.
  runZoned<Future<Null>>(() async {
    runApp(ReduxApp());
.
.
.
  ReduxApp({
    Key key})  : store = Store<AppState>(
          appReducer,
          initialState: AppState.initial(),
          middleware: createStoreTodosMiddleware(
            FirestoreReactiveTodosRepository(Firestore.instance),
            FirestoreReactiveFeedsRepository(Firestore.instance),
            FirestoreReactiveUserFeedsRepository(Firestore.instance),
            AuditAPIRepository(),
            FirebaseUserRepository(FirebaseAuth.instance),
            SCUserRepositoryImpl(),
          ),
