void handlePresentationTriggerIndex(Map data)

  state.currentPresentationPath = triggeredPath;
  state.currentSlideIndex = int.tryParse(data['slideIndex'].toString()) ?? 0;

  // we now have enough information to know what the current presentation should be
  // and by this point, we should already have presentation data
  // but we do a doublecheck
  if (isNew || currentPresentation == null || currentPresentation!.slideQuality < SLIDE_HIGHQ) {
    loadPresentation(
      path: triggeredPath,

      // updateController.add(action); // the loadPresentation should trigger updates anyway
