What would cause a Flutter Redux StoreConnector to not rebuild.

I try to follow the issues religiously on the flutter_architecture_sample. Thank you, to all of you that contribute and ask questions. It helps a lot. I have not seen an issue like this and I could not find the right search query to bring up anything close to my problem. I would really appreciate some help if anyone has an idea as to why this StoreBuilder is not rebuilding. The underlying state of the reducer is two Map<String, Whatevers>'s. I tried to add code without overwhelming the post.

    #View
    return ListView.builder(
                itemCount: eventIDs.length,
                itemBuilder: (BuildContext context, int i) {
                  return StoreConnector<AppState, EventsPageViewModel>(
                      rebuildOnChange: true,
                      onDidChange: (EventsPageViewModel events) {print('${events}');},
                      onInit: (store) =>
                          store.dispatch(FetchEventAction(id: eventIDs[i])),
                      converter: (store) => EventsPageViewModel.fromStore(store),
                      builder: (BuildContext context, EventsPageViewModel events) {
                        print("build ListItem $i ${eventIDs[i]}");
                        if (events.events.containsKey('${eventIDs[i]}')) {
                          return EventCard(
                            event: events.events[eventIDs[i]],
                          );
                        }
                        return Container(
                          child: Card(
                            child: Container(
                              height: 120.0,
                            ),
                          ),
                        );
                      });
                },
              );
    #State
    @immutable
    class Events {
      Events({
        this.loadingStatus,
        this.events,
      });

      factory Events.initial() {
        return Events(
          loadingStatus: Map<String, LoadingStatus>(),
          events: Map<String, EventModel>(),
        );
      }

      final Map<String, LoadingStatus> loadingStatus;
      final Map<String, EventModel> events;

      Events copyWith({
        Map<String, LoadingStatus> loadingStatus,
        Map<String, EventModel> events,
      }) {
        return Events(
          loadingStatus: loadingStatus ?? this.loadingStatus,
          events: events ?? this.events,
        );
      }

      @override
      bool operator ==(Object other) =>
          identical(this, other) ||
          other is Events &&
              runtimeType == other.runtimeType &&
              loadingStatus == other.loadingStatus &&
              const MapEquality().equals(events, other.events);

     @override
     int get hashCode => loadingStatus.hashCode ^ const MapEquality().hash(events);
    }


    #ViewModel
    class EventsPageViewModel {
      EventsPageViewModel({
       @required this.status,
       @required this.events,
     });

     final Map<String, LoadingStatus> status;
     final Map<String, EventModel> events;

     static EventsPageViewModel fromStore(
       Store<AppState> store,
     ) {
       return EventsPageViewModel(
         status: store.state.events.loadingStatus,
         events: store.state.events.events,
       );
     }

     @override
     bool operator ==(Object other) =>
         identical(this, other) ||
         other is EventsPageViewModel &&
             runtimeType == other.runtimeType &&
             status == other.status &&
             const MapEquality().equals(events, other.events);

     @override
     int get hashCode => status.hashCode ^ const MapEquality().hash(events);
    }

I'm trying to get a view to rebuild after it fire off an async action and it return a value to a Map. I don't know if i'm doing the equality check properly

I checked to see if the middleware was firing off the GET Request. It is. I checked to see if the GET request was returning information. It is. I have another async action that is firing. That one returns a List of string and does trigger a rebuild on its StoreConnector.

Does anyone have any clues as to why the StoreConnector does not detect a diff?
