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.
