Succeeding Bloc are not working after latest Bloc migration - flutter

Question

I am using a MultiBlocProvider which is working for all Bloc before I migrate it to v8.0.1. Now, only the first Bloc (SignInBloc) is working.
This is on my main.dart
return MultiBlocProvider(
providers: [
BlocProvider<SignInBloc>(
create: (context) => SignInBloc(
authenticationRepository: authenticationRepository,
userDataRepository: userDataRepository,
),
),
BlocProvider<SignUpBloc>(
create: (context) => SignUpBloc(
authenticationRepository: authenticationRepository,
userDataRepository: userDataRepository,
),
),
Edit: here is my SignInBloc
SignInBloc(
{required this.authenticationRepository,
required this.userDataRepository})
: super(SignInInitialState()) {
on<CheckIfSignedInEvent>(mapCheckIfSignedInEventToState);
}
Future<void> mapCheckIfSignedInEventToState(
CheckIfSignedInEvent event,
Emitter<SignInState> emit,
) async {
try {
bool isSignedIn = await authenticationRepository.checkIfSignedIn();
if (isSignedIn) {
emit(CheckIfSignedInEventCompletedState(true));
} else {
emit(CheckIfSignedInEventCompletedState(false));
}
} catch (e) {
print(e);
emit(CheckIfSignedInEventFailedState());
}
}
I am not sure what to show but here is my SignUpBloc which is similar to my SignInBloc
SignUpBloc(
{required this.authenticationRepository,
required this.userDataRepository})
: super(SignUpInitialState()) {
on<SignUpWithGoogle>(mapSignUpWithGoogleEventToState);
}
Stream<SignUpState> mapSignUpWithGoogleEventToState(
SignUpWithGoogle event,
Emitter<SignUpState> emit,
) async* {
emit(SignUpInProgressState());
try {
User? checkUser = await authenticationRepository.checkIfUserExists();
if (checkUser != null) {
emit(SignUpWithGoogleInitialExistState());
} else {
bool checkDup =
await authenticationRepository.checkIfUserDup(event.name);
if (checkDup == true) {
emit(SignUpWithNameExistState());
} else {
User firebaseUser = await authenticationRepository.signUpWithGoogle();
emit(SignUpWithGoogleInitialCompletedState(firebaseUser));
}
}
} catch (e) {
print(e);
emit(SignUpWithGoogleInitialFailedState());
}
}
My main.dart will call the splash screen which has the declaration of the bloc
late SignInBloc signInBloc;
late SignUpBloc signupBloc;
class _SplashScreenState extends State<SplashScreen> {
#override
void initState() {
super.initState();
signInBloc = BlocProvider.of<SignInBloc>(context);
signupBloc = BlocProvider.of<SignUpBloc>(context);
What I tried to do it to put alot of Print statement in order to check which part is getting called but I don't get why the SignUpBloc is not getting called anymore. Please help. Thanks!
Edit: I tried to debug.
This will trigger my SignInBloc. I'm able to listen to my SignInBloc.
signInBloc.add(CheckIfSignedInEvent());
This should trigger my SignUpBloc. But it doesn't do anything similar to my SignInBloc.
signupBloc.add(SignUpWithGoogle(name: selectedName));
Here's both of my events for comparison:
class CheckIfSignedInEvent extends SignInEvent {
#override
String toString() => 'CheckIfSignedInEvent';
}
class SignUpWithGoogle extends SignUpEvent {
final String name;
SignUpWithGoogle({required this.name});
#override
String toString() => 'SignUpWithGoogleEvent';
}
This is the part where I listen to the states which is both in my splash screen. Only signInBloc is able to listen.
signupBloc.stream.listen((state) {
print('BLOC: signupBloc splash screen init : $state');
});
signInBloc.stream.listen((state) {
print('BLOC: signinBloc splash screen init : $state');
});

It turns out that changing the Stream to Future will fix my issue. async* should also be changed to async
Future<void> mapSignUpWithGoogleEventToState(
SignUpWithGoogle event,
Emitter<SignUpState> emit,
) async {
emit(SignUpInProgressState());
try {
User? checkUser = await authenticationRepository.checkIfUserExists();
if (checkUser != null) {
emit(SignUpWithGoogleInitialExistState());
} else {
bool checkDup =
await authenticationRepository.checkIfUserDup(event.name);
if (checkDup == true) {
emit(SignUpWithNameExistState());
} else {
User firebaseUser = await authenticationRepository.signUpWithGoogle();
emit(SignUpWithGoogleInitialCompletedState(firebaseUser));
}
}
} catch (e) {
print(e);
emit(SignUpWithGoogleInitialFailedState());
}
}
