itemPageCancel method

Implementation

void itemPageCancel({bool useValidation = true, required BuildContext context}) async {
  if (useValidation) {

      // Use the existing callback pattern instead of direct call
      if (saveOrCancelDefaultDialog == null) {

        return;
      }

        case null:

        case true:
          itemPagePost(goBack: true);
          return;
        case false:
          break;
      }
    }
  }
  if (backupItem != null) {
    selectedItem = backupItem;

  }
