Flutter bloc emit() and SchedulerBinding - flutter

Question

I use a SavingState during which I update my User object.
For this I use the SchedulerBindings.
However when creating a user: my object is not update. It updates too late. Why ?
Update : Strangely the same code for user update works
In my form :
Widget build(BuildContext context) {
isUpdateMode = widget.isUpdateMode;
return BlocBuilder<UserBloc, UserState>(builder: (context, state) {
if (state is ItemLoadedState || state is IsSavedState) {
SchedulerBinding.instance.addPostFrameCallback(
(_) => _data = generateItems(_buildPanelList()));
return _buildForm();
}
if (state is SavingState) {
SchedulerBinding.instance.addPostFrameCallback((_) => _savedForm());
print('SavingState: ${item.toJson()}');
return _buildForm();
}
if (state is FailState) return ErrorUI(message: state.message);
if (state is LoadingState) return buildLoading();
return ErrorUI(message: l10n.noDataText);
});
}
In my bloc
Future<void> _onCreateUser(
CreateUserEvent event, Emitter<UserState> emit) async {
try {
emit(SavingState());
print('bloc: ${event.item!.toJson()}');
final item = await repository.create(event.item!);
emit(IsSavedState(user: item));
} on HttpException catch (error) {
emit(
FailState(
message: 'Failed to create user ${event.item!.pseudo}.\n\n$error'),
);
} catch (e) {
emit(
FailState(message: 'Failed to create user ${event.item!.pseudo}.'),
);
}
}
Future<void> _onUpdateUser(
UpdateUserEvent event, Emitter<UserState> emit) async {
try {
emit(SavingState());
final item = await repository.update(event.item!);
emit(IsSavedState(user: item));
} catch (e) {
emit(
FailState(message: 'Failed to update user ${event.item!.pseudo}.'),
);
}
}
In my print I have : bloc before SavingState.
Thanks,
