CupertinoPickerDefaultSelectionOverlay class
A default selection overlay for CupertinoPickers.
It draws a gray rounded rectangle to match the picker visuals introduced in iOS 14.
This widget is typically only used in CupertinoPicker.selectionOverlay. In an iOS 14 multi-column picker, the selection overlay is a single rounded rectangle that spans the entire multi-column picker. To achieve the same effect using CupertinoPickerDefaultSelectionOverlay, the additional margin and corner radii on the left or the right side can be disabled by turning off capStartEdge and capEndEdge, so this selection overlay visually connects with selection overlays of adjoining CupertinoPickers (i.e., other "column"s).
