CupertinoFocusHalo class

Applies an iOS-style focus border around its child when any of child focus nodes gain focus.

The shape of the focus halo does not automatically adapt to the child widget it encloses. You are responsible for specifying a shape that correctly matches the child's geometry by using the appropriate constructor, such as CupertinoFocusHalo.withRect or CupertinoFocusHalo.withRRect.
