In fact you got to return something when you ends PageA. I put you an exemple with a popup to select an adress i made recently, this work exactly the same if this is not a popup.

Future<PlacesDetailsResponse> showAdressPicker({@required BuildContext context}) async {
  assert(context != null);
  return await showDialog<PlacesDetailsResponse>(
    context: context,
    builder: (BuildContext context) => AdressPickerComponent(),
  );
}

You can send a result from Navigator.pop(...) and get it from PageA

Navigator.pop(context, result)

Just put anything you want in result, (here i created a class named PlacesDetailsResponse, use yours or just Int, String...). Now In pageA when you call this 

showAdressPicker(context: context).then((PlacesDetailsResponse value) {
  //do whatever you want here
  // this fires when PageB call previous to PageA
});
