MaterialBannerThemeData class Null safety

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.
