当我在android_alarm_manager回调中使用shared_preferences插件时，尽管我已经遵循了插件文档中的所有步骤，但我仍然会遇到这个异常。
Unhandled Exception: MissingPluginException(No implementation found for method getAll on channel plugins.flutter.io/shared_preferences)
我最近在使用flutter Android Embedding V2的flutter 1.20版本上创建了这个项目，所以它应该自动注册插件。
Flutter Doctor输出：

提前感谢😃
我能够通过删除导致FlutterEngine 发出此警告的包keyboard_visibility: ^0.5.6来解决此问题
