在颤动报警管理器回调中使用插件时发生MissingPlugin异常 [英] MissingPluginException When Using Plugins in Flutter Alarm Manager Callbacks

问题描述

当我在Android_Alarm_MANAGER回调中使用Shared_Preferences插件时，即使我遵循了插件文档中的所有步骤，我仍收到此异常。

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

我最近在Ffltter 1.20版的基础上创建了这个项目，该版本使用Ffltter Android Embedding V2，因此它应该会自动注册插件。

推荐答案

我能够通过删除此程序包keyboard_visibility: ^0.5.6解决此问题，该程序包导致FlutterEngine出现此警告

W/FlutterEngine(10724): Tried to automatically register plugins with FlutterEngine (io.flutter.embedding.engine.FlutterEngine@8ca5659) but could not find and invoke the GeneratedPluginRegistrant.
