QUESTION
I've been working on trying to build a login page with Flutter/Dart and BLoC. So far I've got a login page with two input fields for a username and password and a login button that is built off of rounded_loading_button.dart.
On first pressing the login button with nothing in either field, the appropriate error is returned in the snackbar and the button is reset.
However, the problem I'm having is that if you press the button a second time, the button continues to spin and the snackbar never shows again. It's as if there is no state being returned somehow.
I've stepped through the code, tried to reset the state but I've not found a solution. I've provided all the files below that I'm working with.
Setting LoginUserState.failed seems to only work once in this case and I can't seem to figure out how to reset it so a second attempt will show the snackbar again and any error and also reset the login button.
Main.dart file

a simple solution would be to yield a different state before
QUESTION
I want to use go_router
(https://pub.dev/packages/go_router#redirection) together with Riverpod
.
I have a Provider
and a StreamProvider
, which I would like to combine into a Listenable
so it can be used as the refreshListenable
param of GoRouter
.
I guess I need combine the Provider
and a StreamProvider
into some kind of Provider
(how?).
What is the easiest way to create a Listenable
from a Provider
?
Edit: I understand that this 'negates' the point of Riverpod, but the app is all setup with Riverpod already and I would just like to add go_router.

QUESTION
I am trying to figure out how to make use of Firebase's onAuthStateChanges()
stream to use as a Listenable in the refreshListenable
parameter from the go_router package to redirect whenever the authState changes.
In additon I am using flutter_riverpod for State Mangement.
My code looks like this so far:
I created a simple AuthService class (shrinked down to the most important parts):

QUESTION
I am currently struggling refactoring my routing code with go_router.
I already got some simple routes like /signin
& /signup
, but the problem comes in when I try to make the routing work with a BottomNavigationBar that has multiple screens. I would like to have a separate route for each of them like /home
, /events
& /profile
.
I figured out that I somehow have to return the same widget with a different parameter to prevent the whole screen to change whenever a BottomNavigationBarItem is pressed and instead only update the part above the BottomNavigationBar which would be the screen itself.
I came up with a pretty tricky solution:

QUESTION
SITUATION: I'm trying to set up firebase with my flutter project by following this guide by the firebase team.
PROBLEM: In the final steps of the guide, a FutureBuilder widget is passed to the 'home' property of a MaterialApp widget. However, MaterialApp.router does not have a 'home' property, so I am struggling to complete the set-up (am new to flutter :-)).
Any thoughts on how to solve this problem?
