StreamBuilder is not rebuilding on new event in stream

Question

My StreamBuilder in view:

Widget build(BuildContext context) {
    print("rebuilding..."); // as of now this gets called only on view initialization and never again - i.e. not on new events going through alarmController.stream

    return StreamBuilder(
        stream: widget.bloc.alarmController.stream,
        initialData: Alarm(''),
        builder: (BuildContext context, AsyncSnapshot<Alarm> snapshot) {
          if (!snapshot.hasData) {
            return Center(
              child: Text(StringLiterals.NO_ALARM_DATA_MSG))
            );
          }

          return Switch(
                  activeColor: Colors.red,
                  value: snapshot.data.status == 'Started',
                  onChanged: (bool _value) {
                    _newAlarmValue = _value;
                    _askAlarmConfirmation();
                  }));
        });
  }

meat of my bloc:

AlarmBloc(this.Api) {
    getAlarm();
}
  getAlarm() async {
    Alarm response = await Api.getAlarmStatus();
    alarmController.sink.add(response); // here im adding new event, therefore streambuilder should rebuild, right?
}

And lastly the code I call to initiate new event(in this case it's firebase message):

if(_message.notification.body.contains("Alarm") && IS_LOGGED_IN == true) {
   alarmBloc.getAlarm();
 }

So the problem is StreamBuilder not rebuilding whenever new event passes through alarmController.stream. What could be the reason?

Answer 1

The issue was I was instantiaing my BLOC incorrectly(second one) and working on a second parallel stream and therefore not the one passed to StreamBuilder.
