ZetaSystemBanner class

A banner displays an important, succinct message, and provides action for users to address. It draws the attention to the message by displaying it at the top in various colors.

To display on screen use ScaffoldMessenger.of(context).showMaterialBanner(ZetaSystemBanner()). This will display the banner at the top of the page, below the AppBar.
