SheenBadge class Feedback

A count or a dot at the top-end corner of child, in red with white figures, as iOS badges are: unread messages, items in a cart.

A count of 0 hides the badge; past max it reads "99+". Screen readers hear semanticLabel (the count when null) as the value of child.

SheenBadge(count: unread, child: SheenIconButton(icon: SheenIcons.bell, semanticLabel: 'Notifications', onTap: open))
