Я бы хотел узнать местоположение корпоративных устройств с помощью корпоративного приложения.
Я успешно обнаружил устройство, когда приложение находится на переднем плане, но, кажется, не работает, когда приложение находится в фоновом режиме или убито.
Я пытался использовать pu sh уведомление о запуске службы или broadcastReceiver, когда приложение закрыто или находится в фоновом режиме, но ничего не работает.
Есть ли способ получить местоположение устройства независимо от состояния приложения?

io.flutter.app.FlutterApplication is an android.app.Application that

In most cases you can leave this as-is, but you if you want to provide
additional functionality it is fine to subclass or reimplement
FlutterApplication and put your custom class here.
