In Firebase, I could have the following getter and set up certain mechanism where my app would automatically logout if the output was null (or stay logged in if the output was of type

User

):

dart
Stream<User?> get authChangeStream => _firebaseAuth.authStateChanges();

How can I recreate a similar functionality with Supabase? Currently, I have this:

dart
Stream<User?> get authChangeStream {
    return _authService.onAuthStateChange((event, session) => session!.user);
  }

I am getting the following error:

A value of type 'GotrueSubscription' can't be returned from the function 'authChangeStream' because it has a return type of 'Stream<User?>'

What should I do to get a

Stream

here?

You return the stream subscription, where you can for example close the stream if you are listening to it. You need to create a new stream via

StreamController()

and

add

events to that controller and return the stream from the controller via

controller.stream

.

I know that is possible but never had to do it. Firebase made it so simple and I never had to close/cancel it. Regardless, do you have an example of this? Is it worth opening as an issue on `Supabase_flutter`'s github? It would really help if there was native support for it.

I don't know.

It confuses me too. There are three different ways of getting streams in the database as far as I know. Its so weird.

what do you mean

In the dart library rework. Its open source right? Anyone who knows how to, they can contribute if they want.

Ahhh now I know what you mean. I'm one of them 😂 https://github.com/supabase-community/gotrue-dart/pulls?q=is%3Apr+author%3AVinzent03+is%3Aclosed

When I am done with the current project I am making, I'll try to put some time into it.
