Provides the offset of this element's borderEdge
relative to the
specified parent
.
This is the Dart equivalent of jQuery's
position method. Unlike jQuery's
position, however, parent
can be any parent element of this
,
rather than only this
's immediate offsetParent
. If the specified
element is not an offset parent or transitive offset parent to this
element, an ArgumentError
is thrown.
