AppBarTheme class

Defines default property values for descendant AppBar widgets.

Descendant widgets obtain the current AppBarTheme object using AppBarTheme.of(context). Instances of AppBarTheme can be customized with AppBarTheme.copyWith.

Typically an AppBarTheme is specified as part of the overall Theme with ThemeData.appBarTheme.

All AppBarTheme properties are null by default. When null, the AppBar will use the values from ThemeData if they exist, otherwise it will provide its own defaults.
