GGroup: Theme.of(context).copywith
Hello dev's.. I'm a bit new to flutter, can someone explain me why we should consider 'Theme.of(context).copywith()' instead of directly using 'ThemeData()' Code: bottomNavgationBar: Theme( data: Theme.of(context).copywith ( canvasColor: .......,)) Insted: bottomNavgationBar:

Reddit: OAuth on Flutter really sucks. What's the easiest way?
I've got this working, but it's really ugly and would like to know if there's a better, smooth way to do it. I've done OAuth in web development multiple times, but I got confused on app development.Firstly, it's weird that I'm setting up a localhost server on the user's device. This is to receive the tokens given back from the third-party website that authenticates the user. Some people mentioned deep linking would solve this server problem, but deep linking is barely supported in flutter and code has to be written for iOS and Android separately.Secondly, I have to open a web browser for the user so they can actually visit the third-party website. Once they authenticate and I receive the tokens, I can't close the browser:If I open the URL in a web browser, then closing it (with JavaScript: `window.close()`) would only close one tab and the web browser remains running. I can't send the user back to my app (or can I?).If I use a web view, I can't close it. I tried, but I can't. Web view doesn't run Javascript, which I use to close the window... or I think it works on Android but not iOS. I forgot but it's getting complicated.Is OAuth, which is a major feature, missing on flutter? Am I missing something?

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?
