CupertinoFocusHalo.withRect constructor
Creates a rectangular CupertinoFocusHalo around the child.
For example, to highlight a rectangular section of the widget tree when any button inside that section has focus, one could write:
CupertinoFocusHalo.withRect(
child: Column(
children: <Widget>[
CupertinoButton(child: const Text('Child 1'), onPressed: () {}),
CupertinoButton(child: const Text('Child 2'), onPressed: () {}),
],
),
)
Implementation
const CupertinoFocusHalo.withRect({required this.child, super.key})
: _borderRadius = BorderRadius.zero;
