Flutter：MissingPluginException在频道 plugins.flutter.io/firebase_core 上找不到方法 Firebase#initializeCore 的实现

如何解决Flutter：MissingPluginException在频道 plugins.flutter.io/firebase_core 上找不到方法 Firebase#initializeCore 的实现

我将我的项目从 Flutter 更新到 Flutter 2.0 null-safety。我解决了依赖项之间的所有问题，但是当我运行应用程序控制台时会显示此错误。我发现很多类似的问题，但他们的答案在我的项目中不起作用。

我尝试使用 Flutter clean，
Flutter pub get,
删除缓存，
从设备上卸载应用程序，
添加这个

WidgetsFlutterBinding.ensureInitialized(); await Firebase.initializeApp();

在主要但实际上任何工作。有人有其他建议吗？或者其他可以尝试的事情？
