maybeOf static method
- BuildContext context
Returns the RestorationBucket inserted into the widget tree by the
closest ancestor RestorationScope of context.
To avoid accidentally overwriting data already stored in the bucket by its owner, data should not be stored directly in the bucket returned by this method. Instead, consider claiming a child bucket from the returned bucket (via RestorationBucket.claimChild) and store the restoration data in that child.
This method returns null if state restoration is turned off for this subtree.
Calling this method will create a dependency on the closest
RestorationScope in the context, if there is one.
See also:
- RestorationScope.maybeOf, which is similar to this method, but asserts if no RestorationScope ancestor is found.
Implementation
static RestorationBucket? maybeOf(BuildContext context) {
return context.dependOnInheritedWidgetOfExactType<UnmanagedRestorationScope>()?.bucket;
}
