       <item value="A default selection overlay for [CupertinoPicker]s. 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 [capLeftEdge] and [capRightEdge], so this selection overlay visually connects with selection overlays of adjoining [CupertinoPicker]s (i.e., other &quot;column&quot;s). See also: [CupertinoPicker], which uses this widget as its default [CupertinoPicker.selectionOverlay]." />

The [background] argument default value is [CupertinoColors.tertiarySystemFill]. It must be non-null. The [capLeftEdge] and [capRightEdge] arguments decide whether to add a default margin and use rounded corners on the left and right side of the rectangular overlay.
