Floating action button has inconsistent reacting regions #42693
Description
Problem
FAB has 2 different regions, the outer region (rectangle) and the inner region (circular), and they react to different events:
- Hover of the tooltip reacts to the outer region, because
Tooltipwraps the entire widget - Hover of the inkwell reacts to the inner region, as shown by hover color
- Tap gestures react to the outer region, thanks to
_InputPadding
This brings inconsistency: The gap between the 2 regions reacts to tooltips, but not the hover color (as well as the upcoming mouse cursor feature), but again, reacts to mouse clicks. Ideally we would like the region that hover events react to match that of the tap events; at least we would like only one hovering region, instead of 2 regions for different changes.
If we must use _InputPadding, I suggest we find a way to make it also proxy the mouse events of the InkWell, so that all events react to the outer region.
