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.
