Thank you very much.
Now everything is working perfectly 😊

Hi @Awakennn21 👋
Thanks for opening an issue!
Can you please share a link to a minimal reproduction sample either on GitHub or DartPad? It would be much easier to help if we're able to run/reproduce the issue locally, thanks!

Hi, thank you so much for responding.
Here is the link to the GitHub repo, containing the whole feature:

Hi @Awakennn21 👋
This is because you're registering your bloc as a factory which means each time you use get_it to lookup a bloc, you'll get a different instance and so the BlocBuilder is listening to changes in a different instance than the once you are adding events to. The quick fix would be to change your registration to registerSingleton instead of registerFactory but in general I recommend just providing blocs using BlocProvider and to avoid mixing it with get_it for this exact reason.
Hope that helps, closing for now!

Hi @felangel
Thanks for your response. Just to be 100% sure. Do you want me to instead of using GetIt package inside the BlocProvider's create: function and swap that for manually creating the whole bloc there like this:
return BlocProvider(
lazy: false,
create: (_) => AuthenticationBloc(
createNewUser: CreateNewUser(
repository: AuthenticationRepository_impl(
dataSource: const FireBaseRemoteDataSource()
)
),
authenticateUser: AuthenticateUser(
repository: AuthenticationRepository_impl(
dataSource: const FireBaseRemoteDataSource()
)
)
),
child: _ShouldDisplayLogin ? LoginPage(showRegisterPage: SwitchShownPages) : RegisterPage(showLoginPage: SwitchShownPages)
);
The problem is that this change did not help and the Bloc builder is still only reacting to the UserCreationSuccesfull, omitting the CreatingUserState. I have updated the given above repo and now there is no Get_It package in use yet the problem still remains.
Any help would be appriciated as I am pretty stuck on this

@Awakennn21 it's possible for a bloc to emit states faster than the UI can rebuild. For example:
emit(StateA());
emit(StateB());
In the above scenario the bloc will emit StateA and StateB before the UI can rebuild so you shouldn't assume in your BlocBuilder
that builder
will run with each state. This is not specific to bloc, the same would happen if you called setState
back-to-back.
Hope that helps 👍
