auto_route: ^8.1.3
auto_route_generator: ^8.0.0
build_runner: ^2.4.11

Could someone point me how to exclude “key” argument from build_runner.
I try to create route with single required argument – storyName

@RoutePage()
class StoryView extends StatefulWidget {
  const StoryView({super.key, @pathParam required this.storyName});

  final String storyName;

  @override
  State<StoryView> createState() => _StoryViewState();
}

but after run – flutter packages pub run build_runner watch. Build runner create file auto_router.gr.dart with error:
Undefined class ‘Key’.
Try changing the name to the name of an existing class, or creating a class with the name ‘Key’

/// generated route for
/// [StoryView]
class StoryRoute extends PageRouteInfo<StoryRouteArgs> {
  StoryRoute({
    Key? key,
    required String storyName,
    List<PageRouteInfo>? children,
  }) : super(
          StoryRoute.name,
          args: StoryRouteArgs(
            key: key,
            storyName: storyName,
          ),
          rawPathParams: {'storyName': storyName},
          initialChildren: children,
        );

  static const String name = 'StoryRoute';

  static const PageInfo<StoryRouteArgs> page = PageInfo<StoryRouteArgs>(name);
}
