fix: Can we get location from background service?

ash-hashtag commented 2 years ago

Description I'm trying to call Location().getLocation() from a service created by flutter_background_service plugin, since I want to get location even when app is terminated, and location plugin doesn't seem to support it

Expected behavior Somehow get location from background?

Steps To Reproduce create a service call Location().getLocation() inside the service

Tested on:

Android, API Level 31, real device
iOS, Version XX [e.g. 15], simulator or real device

Other plugins:

flutter_background_service
