ResponsiveNav class

A responsive navigation bar.

It shows a NavigationBar on small screens and a NavigationRail on large screens.

The navigation bar consists of a list of navigation items. Each navigation item is a NavItem object.

It animates itself when the screen size changes.

You can customize the navigation style by using NavStyle class.
