Creates a Material Design secondary tab bar.
Secondary tabs are used within a content area to further separate related content and establish hierarchy.
This sample showcases nested Material 3 TabBars. It consists of a primary
TabBar with nested a secondary TabBar. The primary TabBar uses a
DefaultTabController while the secondary TabBar uses a TabController.
