flutter_supabase auth.signOut() should trigger 'onUnauthenticated'

[seenickcode]

It would be ideal to keep all auth state logic in a single place, such as here, but unfortunately, when calling signOut, nothing in this AuthState implementation gets triggered, thus making the user's code brittle, because we have to code logic like thi to update the route stack, vs having it all done in our AuthState implementation.

Hi @seenickcode !

That sounds like an amazing idea. If you don't mind, could you open an issue in supabase_flutter?

Done! supabase/supabase-flutter#35
