I have a sign in cubit, which will take two parameters, email and password. then it will ask repository to give him response of that request. Before calling the function of repository I emit loading state, and when I received data from repository another state is emitted which is SigninLoaded. My SigninCubit:
final SignInRepository signInRepository;
SigninCubit({required this.signInRepository}) : super(SigninInitial());
Future<void> signIn({String email = '', String password = ''}) async {
print("Cubit is invoked");
emit(SigninInLoading());
Timer(Duration(seconds: 0), () async {
await signInRepository
.signIn(email: email, password: password)
.then((signinModel) {
// print("SignIn Model is : ${signinModel}");‹‹
emit(SigninLoaded(signInModel: signinModel));
});
});
}
}
SigninState
@immutable
abstract class SigninState {}
class SigninInitial extends SigninState {}
class SigninInLoading extends SigninState {}
class SigninLoaded extends SigninState {
SignInModel? signInModel;
SigninLoaded({required this.signInModel});
}
This is how I invoked my signinCubit from LoginPage class.
BlocProvider.of<SigninCubit>(context).signIn(email: email, password: password);
When signinCubit is invoked from LoginPage class, I see it's response in the same class using BlocBuilder like this;
BlocBuilder<SigninCubit, SigninState>(
builder: (context, state) {
if ((state is SigninInitial)) {
print("Initial State");
} else if (state is SigninInLoading) {
return Center(
child: CircularProgressIndicator(
color: AppColors.mainColor,
),
);
} else {
final signinData = (state as SigninLoaded).signInModel;
data = signinData;
}
But when I try to access response or the last emitted state which was SigninLoaded, I get initial state in other class, I tried to get response in Profile class like this;
BlocBuilder<SigninCubit, SigninState>(
builder: (context, state) {
print("State : $state");
if (state is SigninLoaded) {
name = (state as SigninLoaded).signInModel?.data?.firstName;
print("Name $name");
}
return Text(
'Welcome, ${name}!',
style: TextStyle(
color: Colors.black,
fontSize: 20,
fontWeight: FontWeight.w800,
),
);
},
),
And I get no response back, because it says it is in initial state.
Even though I have provided Blocs as well like so;
BlocProvider to LoginPage class;
MaterialPageRoute(
builder: (_) => BlocProvider(
create: (BuildContext context) =>
SigninCubit(signInRepository: signInRepository),
child: LoginPage(),
),
);
BlocProvider to Profile class;
MaterialPageRoute(
builder: (_) => BlocProvider(
create: (context) =>
SigninCubit(signInRepository: signInRepository),
child: Profile(),
));
CodePudding user response:
May be Im wrong, but in my oppinion, if you want to use the SignInModel in Profile page, you've to call signIn function Again
Another Solution : define just one BlocProvider of SignInCubit as parrent of both Profile page and SignIn page, for example :
MaterialPageRoute( builder: (_) => BlocProvider( create: (context) => SigninCubit(signInRepository: signInRepository), child: MyApp(), ));
Save signinModel or (sign in information) in local database, and when we enter ProfilePage, get it from db
