clone method
Returns a copy of this node.
If deep
is true
, then all of this node's children and decendents are
copied as well. If deep
is false
, then only this node is copied.
Implementation
@override
Element clone(bool deep) {
final result = Element._(localName, namespaceUri)
..attributes = LinkedHashMap.from(attributes);
return _clone(result, deep);
}
