Flutter – listener not trigger when using local bloc (bloc: parameter)

I have a bloc which has global state (BlocProvider is initialised before Material App). In the onPreesed callback of a button I have a bloc listener:

BlocListener<RiskAssesmentValueCubit, RiskAssesmentValueState>(
                    bloc: riskAss
                      ..checkActualVersusCalculated(user.customerId, riskAttitudeQuestionsDetails),
                    listener: (BuildContext context, RiskAssesmentValueState state) {
                      print('Listener called');

                      if (state is RiskAssesmentValueDifferent) {
                        print('Listener called');
                      }
                    },
                  );

the bloc: param is calling the method in the cubit correctly. The states in the cubit are updating. But the listener is never triggered. I grab the bloc in the build method

@override
  Widget build(BuildContext context) {
   final RiskAssesmentValueCubit riskAss = context.read<RiskAssesmentValueCubit>();

.....
} 

I tried a builder and that is also not being triggered. I think I might not understand the bloc: param correctly. But I think I should be able to access the builder/listener.
