dismissible property
final
Specifies if the barrier will be dismissed when the user taps on it.
If true, and onDismiss is non-null, onDismiss will be called, otherwise the current route will be popped from the ambient Navigator.
If false, tapping on the barrier will do nothing.
See also:
- ModalRoute.barrierDismissible, which controls this property for the ModalBarrier built by ModalRoute pages.
