AppBarTheme class Null safety
Overrides the default values of visual properties for descendant AppBar widgets.
Descendant widgets obtain the current AppBarTheme object with
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
compute its own default values, typically based on the overall theme's
ThemeData.colorScheme, ThemeData.textTheme, and ThemeData.iconTheme.
