Scaffold implements the basic structure of a Material Design or iOS Cupertino visual layout. For Material Design, the Scaffold widget can contain multiple Material Design components:
- body: The primary content of the scaffold. Its displayed below AppBar, if any.
- AppBar: An app bar consists of a toolbar and potentially other widgets.
- TabBar: A Material Design widget that displays a horizontal row of tabs. This is generally used as part of AppBar.
- TabBarView: A page view that displays the widget that corresponds to the currently selected tab. Typically used in conjunction with TabBar and used as a body widget.
- BottomNavigationBar: Bottom navigation bars make it easy to explore and switch between top-level views in a single tap.
