If the error is actually caused by the code you posted, I'd just add a check to ensure no new events are added after dispose() was called.

class ServiceBloc extends MainBloc {
  final _repo = new Repo();
  final PublishSubject _serviceController =
      new PublishSubject();
  Observable get allServices => _serviceController.stream;
  getAllServices() async {
    // do nothing if already disposed
    if(_isDisposed) {
      return;
    }
    appIsLoading();
    ServiceModel movieItem = await _repo.getAllServices();
    _serviceController.sink.add(movieItem);
    appIsNotLoading();
  }

  bool _isDisposed = false;
  void dispose() {
    _serviceController.close();
    _isDisposed = true;
  }
}

ServiceBloc serviceBloc = new ServiceBloc();
