Ah, I see.

Well, that's another profit in using BLoC architecture – you don't even need to worry about things like this. If master and detail screens share the same BLoC (which makes sense if they use the same data), there's nothing you need to do manually – updating data in BLoC forces an update of the UI.

If they don't use the same BLoC, I usually prefer waiting for result and updating data. E.g. we launch a new page with `final result = await Navigator.of(context).push()` and after the new page is popped, we get the result and decide what to do with – probably, update the old page.
