I failed flutter web build

I'm going to use flutter web and firebase. I'm going to do a simple build test, but if I build it, It stops at 'await ui.webOnlyInitializePlatform();' of web_entrypoint.dart.

pubspec.yaml

environment:
  sdk: ">=2.12.0 <3.0.0"

dependencies:
  flutter:
    sdk: flutter

  # Use with the CupertinoIcons class for iOS style icons.

main.dart

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  // Firebase.initializeApp();
  runApp(MyApp());
}

class MyApp extends StatelessWidget {

  @override
  Widget build(BuildContext context) {
    return FlutterWebFrame(
      builder: (context) {
        return MaterialApp(
          home: Scaffold(
            appBar: AppBar(
              title: Text('Title 123'),
            ),
            body: Center(
              child: Text('Body Text'),
            ),
          ),
        );
      },
      maximumSize: Size(768.0, 1024.0), // Maximum size
      enabled: true, // default is enable, when disable content is full size
      backgroundColor: Colors.grey, // Background color/white space
    );
  }
}

When build from Chrome, debug stops here.

// @dart=2.12
// Flutter web bootstrap script for package:omd_test/main.dart.

import 'dart:ui' as ui;
import 'dart:async';

import 'package:omd_test/main.dart' as entrypoint;
import 'package:flutter_web_plugins/flutter_web_plugins.dart';
import 'package:omd_test/generated_plugin_registrant.dart';

typedef _UnaryFunction = dynamic Function(List<String> args);
typedef _NullaryFunction = dynamic Function();
Future<void> main() async {
  registerPlugins(webPluginRegistrar);
  await ui.webOnlyInitializePlatform(); //debug stop here
  if (entrypoint.main is _UnaryFunction) {
    return (entrypoint.main as _UnaryFunction)(<String>[]);
  }
  return (entrypoint.main as _NullaryFunction)();
}

If I 'step over' after the debugger stops, the following error is output.

TypeError: Cannot read properties of undefined (reading 'app')

May I know the cause and solution of this problem? Thank you.
