Implementation

@override

  // deserialize
  super.deserialize(xml);

  // clear items
  this.items.forEach((item) => item.dispose());
  this.items.clear();

  // build items
  List<MenuItemModel> items = findChildrenOfExactType(MenuItemModel).cast<MenuItemModel>();

  // set prototype
  if ((!S.isNullOrEmpty(datasource)) && (items.isNotEmpty))
  {
    prototype = S.toPrototype(items[0].element.toString());
    items.removeAt(0);
  }

  // build items
  items.forEach((item) => this.items.add(item));
