NavigationRail | BottomNavigationBar | TabBar

Описание: The navigation rail is meant for layouts with wide viewports, such as a desktop web or tablet landscape layout. For smaller layouts, like mobile portrait, a BottomNavigationBar should be used instead.

The bottom navigation bar consists of multiple items in the form of text labels, icons, or both, laid out on top of a piece of material. It provides quick navigation between the top-level views of an app. For larger screens, side navigation may be a better fit.
