margin property
final
Empty space to surround the snack bar.
This property is only used when behavior is SnackBarBehavior.floating. It can not be used if width is specified.
If this property is null, then SnackBarThemeData.insetPadding of
ThemeData.snackBarTheme is used. If that is also null, then the default is
EdgeInsets.fromLTRB(15.0, 5.0, 15.0, 10.0)
.
If this property is not null and hitTestBehavior is null, then hitTestBehavior default is HitTestBehavior.deferToChild.
Implementation
final EdgeInsetsGeometry? margin;
