问如何修复:没有在通道plugins.fltter.io/ getAll _preferences上找到方法的实现

EN

我已经研究这个问题将近半天了。我正在尝试使用Flutter的SharedPreferences包在应用程序的存储中存储密钥/值。当我通过SharedPreferences新建一个await SharedPreferences.getInstance()时，它构建和运行正常，但是当应用程序到达该代码行时，它会崩溃，并出现以下错误：

MissingPluginException (MissingPluginException(No implementation found for method getAll on channel plugins.flutter.io/shared_preferences))

我找到了其他Stackoverflow帖子，但它们并没有帮助解决这个问题：

• MissingPluginException(No implementation found for method getAll on channel plugins.flutter.io/shared_preferences) while getting FCM in background
• Unhandled Exception: MissingPluginException(No implementation found for method getAll on channel plugins.flutter.io/ for many packages on Flutter
• Flutter Test: MissingPluginException(No implementation found for method getAll on channel plugins.flutter.io/shared_preferences)
• Flutter MissingPluginException(No implementation found for method getAll on channel ...) in release app
• Unhandled Exception: MissingPluginException(No implementation found for method flutterToWatch on channel it.example.watch)
• Flutter: Unhandled exception: MissingPluginException(No implementation found for method getAll on channel plugins.flutter.io/shared_preferences)
• https://github.com/flutter/flutter/issues/98473

通过所有这些，我尝试了以下几点：

• flutter pub get
• io.flutter.plugins.sharedpreferences.SharedPreferencesPlugin.registerWith(registry.registrarFor("io.flutter.plugins.sharedpreferences.SharedPreferencesPlugin"));
• Since I on iOS：SharedPreferencesIOS.registerWith();
• https://pub.dev/packages/flutter_isolate
• flutter clean && flutter pub get
• SharedPreferences.setMockInitialValues({});

在运行/执行上述步骤之后，我重新启动了编辑器(VSC)。我甚至安装了带有颤振扩展的Android，并试用了它，结果失败了。我试着从命令行运行，但它仍然返回相同的错误。我试着重新启动我的电脑，卸载和重新安装颤振和飞镖，以供笑。现在我真的不知道该怎么办。我错过了什么步骤？
