=============================================
我刚更新了最新版本1.2.2之后，去掉这段代码，
首先https://github.com/brewkits/native_workmanager/issues/17这个问题得到了解决
其次https://github.com/brewkits/native_workmanager/issues/18我没有按照去自注册插件
我的后台任务中的通知和读取Google health的数据也能正常触发。
而且我在触发后台任务时，我前台通过蓝牙连接设备也没有触发断开了。
这个是我收到的奇怪的表现，但是我很喜欢这个表现。只是有点不明白你们做了什么调整。
1、首先第一蓝牙不断开，是因为我默认设置的是registerPlugins: false。
2、但是我没有自注册flutter的通知组件，按你所说，理论是不会触发，结果我得到的是会触发通知，我也没注册Google health的插件，它也能正常去读取到数据。这是表现让我很意外，但是是我想要的结果。
以下是我的核心代码：
/// 在 `main` 里于 [WidgetsFlutterBinding.ensureInitialized] 之后调用一次即可。
///
/// **Android**：使用 [DartWorker] 且需在进程被杀后仍能执行时，宿主还需完成
/// [native_workmanager Android 配置](https://github.com/brewkits/native_workmanager/blob/main/doc/ANDROID_SETUP.md)
///（自定义 `Application` + `Configuration.Provider`、移除默认 WorkManager 初始化等）。
/// 主工程 `urevo_flutter` 已接入 `UrevoApplication` 与清单项。
