ZdsAppBar class

An app bar with Zds styling.

Typically used in Scaffold.appBar, placing it at the top of the screen. By using the bottom property, another widget can be displayed below this appbar, typically a ZdsResponsiveTabBar or a ZdsTabBar.

Scaffold(
  appBar: ZdsAppBar(
    title: Text("I'm an appbar!")
    bottom: ZdsTabBar()
  ),
)

By default, if no leading widget is provided, the appbar will provide an IconButton to return to the previous page in the Navigator's stack.
