maybeOf static method
- BuildContext context
The closest instance of this class that encloses the given context.
If there is no enclosing ScrollNotificationObserver widget, then null is returned.
Calling this method will create a dependency on the closest
ScrollNotificationObserver in the context, if there is one.
See also:
- ScrollNotificationObserver.of, which is similar to this method, but asserts if no ScrollNotificationObserver ancestor is found.
Implementation
static ScrollNotificationObserverState? maybeOf(BuildContext context) {
return context
.dependOnInheritedWidgetOfExactType<_ScrollNotificationObserverScope>()
?._scrollNotificationObserverState;
}
