我在Scaffold抽屉里切换应用程序主题。每当我切换主题时，抽屉立即关闭。有没有办法在父级重建时保持抽屉窗体关闭？

return Drawer(
      child: ListView(
        // Important: Remove any padding from the ListView.
        padding: EdgeInsets.zero,
        children: <Widget>[
          const DrawerHeader(
            decoration: BoxDecoration(color: Color(0x4D4971FF)),
            //https://gist.github.com/lopspower/03fb1cc0ac9f32ef38f4
            child: Text(
              'Header',
              style: style,
            ),
          ),
          ListTile(
            leading: const Icon(Icons.brush),
            title: const Text(
              'Dark Mode',
              style: style,
            ),
            trailing: Switch(
              value: context.read<ThemeModeCubit>().state == ThemeMode.dark,
              onChanged: (value) {
                context.read<ThemeModeCubit>().toggleBrightness();
              },
            ),
          ),
       ]
      ),
   );

这是使用Cubit的构建器。StackOverflow说
看起来你的帖子大部分是代码;请补充一些细节。

class AppView extends StatelessWidget {
  const AppView({super.key});

  @override
  Widget build(BuildContext context) {
    return BlocBuilder<AuthenticationBloc, AuthenticationState>(
        builder: (context, authState) {
          final _router = AppRouter(
            status: authState.status,
            initialMessage: null,
          ).router;
          return MaterialApp.router(
            
            themeMode: context.watch<ThemeModeCubit>().state,
            debugShowCheckedModeBanner: false,
            routerConfig: _router,
          );
        },
     
    );
  }
}

这是腕尺

class ThemeModeCubit extends HydratedCubit<ThemeMode> {
  ThemeModeCubit() : super(ThemeMode.system);

  void toggleBrightness() {
    emit(state == ThemeMode.light ? ThemeMode.dark : ThemeMode.light);
  }

  @override
  ThemeMode? fromJson(Map<String, dynamic> json) {
    return ThemeMode.values[json['themeMode'] as int];
  }

  @override
  Map<String, dynamic>? toJson(ThemeMode state) {
    return <String, int>{'themeMode': state.index};
  }
}

• • 更新**

class AppView extends StatelessWidget {
  const AppView({super.key});

  @override
  Widget build(BuildContext context) {
    final _router = AppRouter(
      status: context.watch<AuthenticationBloc>().state.status,
      initialMessage: null,
    ).router;
    return MaterialApp.router(
        theme: AppTheme.of(context).light(),
        darkTheme: AppTheme.of(context).dark(),
        themeMode: context.watch<ThemeModeCubit>().state,
        debugShowCheckedModeBanner: false,
        routerConfig: _router,
      );
   
  
  }
}
