RootRestorationScope constructor Null safety

const RootRestorationScope(
  1. {Key? key,
  2. required String? restorationId,
  3. required Widget child}
)

Creates a RootRestorationScope.

Providing null as the restorationId turns off state restoration for the child and its descendants.

The child must not be null.

Implementation

const RootRestorationScope({
  super.key,
  required this.restorationId,
  required this.child,
}) : assert(child != null);
