Generated Route has no key constructor parameter, when it is the only parameter in the corresponding widget/screen

[Sevastyan]

This is my screen:

@RoutePage()
class InitializationInvitationMissingScreen extends StatelessWidget {
  const InitializationInvitationMissingScreen({super.key});

  static const route = InitializationInvitationMissingRoute.new;

  @override
  Widget build(BuildContext context) => ...;
}

and this is what's getting generated:

/// generated route for
/// [_i6.InitializationInvitationMissingScreen]
class InitializationInvitationMissingRoute extends _i16.PageRouteInfo<void> {
  const InitializationInvitationMissingRoute(
      {List<_i16.PageRouteInfo>? children})
      : super(
          InitializationInvitationMissingRoute.name,
          initialChildren: children,
        );

  static const String name = 'InitializationInvitationMissingRoute';

  static const _i16.PageInfo<void> page = _i16.PageInfo<void>(name);
}

Notice that I cannot pass key to the route.

This is my workaround:

@RoutePage()
class InitializationInvitationMissingScreen extends StatelessWidget {
  const InitializationInvitationMissingScreen({super.key, required this.placeholder});

  final String placeholder;

  static const route = InitializationInvitationMissingRoute.new;

  @override
  Widget build(BuildContext context) => WalletScaffold(
        title: context.l10n.appName,
        keycard: const KeycardBlank(),
        children: [
          const SizedBox(height: 48),
          InfoWidget(
            title: context.l10n.invitationMissingTitle,
            body: context.l10n.invitationMissingBody,
          ),
        ],
      );
}

it generates:

// generated route for
/// [_i6.InitializationInvitationMissingScreen]
class InitializationInvitationMissingRoute
    extends _i16.PageRouteInfo<InitializationInvitationMissingRouteArgs> {
  InitializationInvitationMissingRoute({
    _i18.Key? key,
    required String placeholder,
    List<_i16.PageRouteInfo>? children,
  }) : super(
          InitializationInvitationMissingRoute.name,
          args: InitializationInvitationMissingRouteArgs(
            key: key,
            placeholder: placeholder,
          ),
          initialChildren: children,
        );

  static const String name = 'InitializationInvitationMissingRoute';

  static const _i16.PageInfo<InitializationInvitationMissingRouteArgs> page =
      _i16.PageInfo<InitializationInvitationMissingRouteArgs>(name);
}
