MaterialBannerThemeData class
Defines the visual properties of MaterialBanner widgets.
Descendant widgets obtain the current MaterialBannerThemeData object using
MaterialBannerTheme.of(context). Instances of MaterialBannerThemeData
can be customized with MaterialBannerThemeData.copyWith.
Typically a MaterialBannerThemeData is specified as part of the overall Theme with ThemeData.bannerTheme.
All MaterialBannerThemeData properties are null by default. When null,
the MaterialBanner will provide its own defaults.
