How to fetch and save the device location periodically while the Flutter app is closed

[GoedertDalmolin]

Recently, I came across a situation where I needed to save the user's current device location every hour. This needs to happen while the app is completely closed (not just minimized or running in the background).

So far, I haven't found any solution capable of achieving this with Flutter.

I even tried using the silent push concept from Firebase Messaging to trigger a message periodically, wake up the app, and save the location.

Example:

FirebaseMessaging.onBackgroundMessage(firebaseMessagingBackgroundHandler);

@pragma('vm:entry-point')
    Future<void> firebaseMessagingBackgroundHandler(RemoteMessage message) async {
      try {
        await getAndSaveLocation();
      } catch (e) {
        log(e.toString());
      }
    }

However, no Flutter package was able to fetch the location while the app was closed (both on Android and iOS).

I also tried using the WorkManager package but had no success.

Is there any solution for this scenario?

I tested the following packages to try to fetch the location:
location, geolocator, and background_location.
