SnackBarThemeData class Null safety

Customizes default property values for SnackBar widgets.

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

Typically a SnackBarThemeData is specified as part of the overall Theme with ThemeData.snackBarTheme. The default for ThemeData.snackBarTheme provides all null properties.

All SnackBarThemeData properties are null by default. When null, the SnackBar will provide its own defaults.
