Proxy in a provider

[naghinezhad]

Is this the correct way to proxy a provider?
I want some providers to act like proxies and reset their internal state when the isAuthenticated status in AuthProvider changes.
The scenario is: when the user logs in (isAuthenticated == true), everything works normally. But when the user logs out (isAuthenticated == false), I want the dependent providers to reset.

I've implemented this using ChangeNotifierProxyProvider, but I'm not sure if it's correct. I’d appreciate any feedback or suggestions.

List<SingleChildWidget> getProviders() {
  return [
    ChangeNotifierProvider(create: (_) => ThemeProvider()),
    ChangeNotifierProvider(create: (_) => LocaleProvider()),
    ChangeNotifierProvider(create: (_) => PackageInfoProvider()),
    ChangeNotifierProvider(create: (_) => AuthProvider()),

    ChangeNotifierProxyProvider<AuthProvider, NotificationProvider>(
      create: (_) => NotificationProvider(),
      update: (_, authProvider, previous) =>
          authProvider.isAuthenticated
              ? (previous ?? NotificationProvider())
              : NotificationProvider(),
    ),

    ChangeNotifierProxyProvider<AuthProvider, UserProvider>(
      create: (_) => UserProvider(),
      update: (_, authProvider, previous) =>
          authProvider.isAuthenticated
              ? (previous ?? UserProvider())
              : UserProvider(),
    ),
  ];
}

class AuthProvider with ChangeNotifier {
  bool isAuthenticated = false;

  void changeIsAuthenticated({required bool status}) {
    isAuthenticated = status;
    notifyListeners();
  }
}

Is this a valid approach for resetting providers when the user logs out?
Is there a cleaner or better way to achieve this?
Is this solution safe and efficient for production use?
