Implementation

@override
void deserialize(XmlElement xml)
{

  // deserialize
  super.deserialize(xml);

  // properties
  double ratio = S.toDouble(Xml.get(node: xml, tag: 'ratio')) ?? -1;
  if (ratio >= 0 && ratio <= 1)
  {
    if (vertical)
         height = "${ratio * 100}%";
    else width  = "${ratio * 100}%";

  dividerColor  = Xml.get(node: xml, tag: 'dividercolor');
  dividerWidth  = Xml.get(node: xml, tag: 'dividerwidth');
  dividerHandleColor  = Xml.get(node: xml, tag: 'dividerhandlecolor');

  // remove non view children
