Reddit: Any good patterns for writing protected routes?
Hey everyone, I've just started working with flutter and I've kind of hit a wall that I can't seem to find any solid documented solutions for (Even though it seems relatively simple to solve)Does anyone know a good way of protecting routes and redirecting users back to the login page if they aren't authenticated.Given this example of routes:

Map<String, WidgetBuilder> appRoutes = { '/': (context) => HomeScreen(), '/library': (context) => LibraryManagementScreen(), '/login': (context) => LoginScreen(), }; 

I'd want to page to initially go through HomeScreen and be redirected to either /library or /login based on authenticated status. I'd also users to be redirected to /login if they logout while on the /library screen.I tried implementing this with an AuthGuard class that would make the guarded routes look like:

 AuthGuard(builder: (context, user) => LibraryManagementScreen(user: user()) 

but I'd get errors if I ran Navigator.pushRoute from the build method (which makes sense now) and If I just had the AuthGuard display the Login widget it'd constantly fire the build function for the AuthGuard and the app would spazz out from FirebaseAuth.instance.onAuthStateChanged being updated every time I interacted with my application.Here's a snippet of the AuthGuard

class AuthGuard extends StatelessWidget { AuthGuard({ Key key, @required this.builder }): super(key: key); final Function(BuildContext context, User user) builder; @override Widget build(BuildContext context) { // This gets called over and over again return StreamBuilder<FirebaseUser>( stream: FirebaseAuth.instance.onAuthStateChanged, builder: (BuildContext context, snapshot) { if (snapshot.connectionState == ConnectionState.waiting) { print("Splash screen"); return SplashScreen(); } else { if (snapshot.hasData) { return FutureBuilder( future: FirebaseUserService.getOrCreateUser(snapshot.data.uid), builder: (BuildContext context, AsyncSnapshot<User> snapshot) { switch (snapshot.connectionState) { case ConnectionState.none: case ConnectionState.waiting: case ConnectionState.active: return SplashScreen(); default: return builder(context, snapshot.data); } } ); } } return LoginScreen(); } ); } } 

I feel like I'm just rambling here, so the TLDR question is:Does anyone have a good example of authentication using a stream while using routes for the navigator?
