@override
void deserialize(XmlElement xml) {
  // deserialize
  super.deserialize(xml);

  // properties
  pager = Xml.get(node: xml, tag: 'pager');
  transition = Xml.get(node: xml, tag: 'transition');
  currentpage = Xml.get(node: xml, tag: 'initialpage') ?? 1;

  // clear options
  for (var page in pages) {
    page.dispose();
  }
  pages.clear();

  // build pages
  _buildPages();
