Interface for RenderObjects to implement when they want to support being tapped, etc.
These handlers will only be called if the relevant flag is set
(e.g. handleSemanticTap will only be called if
SemanticsNode.canBeTapped is true, handleSemanticScrollDown will only
be called if SemanticsNode.canBeScrolledVertically is true, etc).

Methods
-
performAction(

Invocation invocation) → dynamic -
Invoked when a non-existent method or property is accessed.
inherited -
