shape property Null safety

ShapeBorder? shape

Default value for SnackBar.shape.

If null, SnackBar provides different defaults depending on the SnackBarBehavior. For SnackBarBehavior.fixed, no overriding shape is specified, so the SnackBar is rectangular. For SnackBarBehavior.floating, it uses a RoundedRectangleBorder with a circular corner radius of 4.0.
