An application that uses material design.

A convenience widget that wraps a number of widgets that are commonly required for material design applications. It builds upon a WidgetsApp by adding material-design specific functionality, such as AnimatedTheme and GridPaper. This widget also configures the top-level Navigator's observer to perform Hero animations.

See also:

  • Scaffold, which provides standard app elements like an AppBar and a Drawer.
  • Navigator, which is used to manage the app's stack of pages.
  • MaterialPageRoute, which defines an app page that transitions in a material-specific way.
  • WidgetsApp, which defines the basic app elements but does not depend on the material library.
