FabTopOffsetY mixin Null safety

Mixin for a "top" floating action button location, such as FloatingActionButtonLocation.startTop.

The adjustment, typically kMiniButtonOffsetAdjustment, is ignored in the Y axis of "top" positions. For "top" positions, the X offset is adjusted to move closer to the edge of the screen. This is so that a minified floating action button appears to align with CircleAvatars in the ListTile.leading slot of a ListTile in a ListView in the Scaffold.body.
