Я пытаюсь включить пакет Zefyr в свой проект, но я получаю эту ошибку после его импорта.

 /C:/Users/Ahmed/flutter/.pub-cache/hosted/pub.dartlang.org/url_launcher_platform_interface-1.0.9/lib/link.dart:85:21: Error: Method not found: 'SystemNavigator.routeInformationUpdated'.
    SystemNavigator.routeInformationUpdated(location: routeName);
                    ^^^^^^^^^^^^^^^^^^^^^^^
/C:/Users/Ahmed/flutter/.pub-cache/hosted/pub.dartlang.org/url_launcher_platform_interface-1.0.9/lib/link.dart:108:12: Error: Getter not found: 'Router'.
    return Router.of(context) != null;
  

Я попытался удалить папку и получить pub, но тщетно, есть предложения ?.
