TransparentPointer

Bases: LayoutControl

TransparentPointer is the solution to "How to pass through all gestures between two widgets in Stack" problem.

For example, if there is an Button inside Container with GestureDetector then tapping on a button won't be "visible" to a gesture detector behind it. With TransparentPointer a tapping event doesn't stop on a button, but goes up to the parent, similar to event bubbling in HTML/JS.
