This shall be accomplished by:- The method shall only be a lookup for a supplier, no actual computation shall be made.
- The result of the supplier must hold the requirements of the result
of
WidgetElement.getAttribute(String). Especially it must not returnnull. - If the attribute isn't set on the widget, the method must return
null.
- Overrides:

attr- the name of the attribute to look for.- Returns:
- a supplier which will return the actual attribute value or
nullif the attribute isn't set for the widget.
