Multiple notifyListeners in flutter ChangeNotifier trigger only one build in widget

Question

I have Flutter app with simple Provider and Consumer flow class SomeProvider with ChangeNotifier. My SubscriptionProvider has next methods:

 methodA() async {
    isLoading = true;
    data = {};

    notifyListeners();

    await Future.delayed(Duration.zero, otherMethod);

    methodB();
  }

  methodB() {
    isLoading = false;
    data = {
 
    notifyListeners();
  }

Widget Code:

Consumer<SomeProvider>(
  builder: (ctx, someProvider, _) {
    if (someProvider.isLoading) {
      return WidgetC();
    }


    return WidgetD();
  }
)

My problem is that when methodA is called build runs only once. On the other hand if I run await Future.delayed(Duration(seconds: 2), otherMethod); instead of await Future.delayed(Duration.zero, otherMethod); everything works fine and I have two builds. Are there any ways to perform build every time I call notifyListeners in provider.
