InfoBadge class

Badging is a non-intrusive and intuitive way to display notifications or bring focus to an area within an app - whether that be for notifications, indicating new content, or showing an alert. An InfoBadge is a small piece of UI that can be added into an app and customized to display a number, icon, or a simple dot.

InfoBadge is built into NavigationView, but can also be placed as a standalone widget, allowing you to place InfoBadge into any control or piece of UI of your choosing. When you use an InfoBadge somewhere other than NavigationView, you are responsible for programmatically determining when to show and dismiss the InfoBadge, and where to place the InfoBadge.
