Use case

I am currently having difficulties to detect if a mouse right click or mouse middle click has happened outside of a widget. This is really necessary to display a custom menus in a desktop application.

Currently, TapRegion widget only detects left mouse click for onTapInside and onTapOutside. Thus, there is no way currently to detect if a right click or middle click event has happened outside of the region of a widget. On the other-hand, GestureDetector can detect right click etc but no way to detect if the click has happened outside of the GestureDetector.

Proposal

It would be really nice to have TapRegion detect all kinds of mouse button click event.
