仅当使用 运行我的应用程序时才会发生此错误web (Chrome)。如果我使用Android Emulator我不会收到此错误。

我提到了一些帖子，例如Widget test failed with No MediaQuery widget found、No MediaQuery widget heavenfound、No MediaQuery heaven can be find? 和其他帖子，但仍然无法解决此错误。

app.dart：

\n

import \'package:flutter/material.dart\';\n\xe2\x80\xa6\n\nclass App extends ConsumerStatefulWidget {\n  const App({Key? key}) : super(key: key);\n\n  @override\n  ConsumerState<App> createState() => _AppState();\n}\n\nclass _AppState extends ConsumerState<App> {\n  @override\n  void initState() {\n    super.initState();\n    kIsWeb ? null : \xe2\x80\xa6;\n  }\n\n  @override\n  Widget build(BuildContext context) {\n    \xe2\x80\xa6\n\n    return Scaffold(\n      body: \xe2\x80\xa6,\n    );\n  }\n}\n

我不太确定错误是否源自这一行：

\n

runApp(const ProviderScope(child: MaterialApp(home: HelloWorld())));\n

我该如何修复这个错误？如果有人可以提供建议，我们将不胜感激。先感谢您！

我通过设置解决了这个错误FlutterError.demangleStackTrace：

import 'package:stack_trace/stack_trace.dart' as stack_trace;

void main() {
  runApp(const HelloWorld());
  FlutterError.demangleStackTrace = (StackTrace stack) {
    if (stack is stack_trace.Trace) return stack.vmTrace;
    if (stack is stack_trace.Chain) return stack.toTrace().vmTrace;
    return stack;
  };
}
