noSuchMethod(
Invocation invocation) → dynamic -

shouldRelayout(
covariant PopupPositionDelegate oldDelegate) → bool -
Called whenever a new instance of the custom layout delegate class is
provided to the RenderCustomSingleChildLayoutBox object, or any time
that a new CustomSingleChildLayout object is created with a new instance
of the custom layout delegate class (which amounts to the same thing,
because the latter is implemented in terms of the former).
