I added this package to my project using github link. Now this worked for me. Try adding to your pubspec.yaml:

background_location:
    git:
      url: https://github.com/Almoullim/background_location.git
      ref: master

It finally worked using the way you mentioned.
But I really wish we didn't have to do it this way!

BackgroundLocatorService.kt file edit in past this code to your issue fixed
path: .pub-cache/hosted/pub.dartlang.org/background_location 0.8.1/android/src/main/kotlin/com/almoullim/background_location/BackgroundLocationService.kt

override fun onRequestPermissionsResult(requestCode: Int, permissions: Array, grantResults: IntArray): Boolean {
Log.i(BackgroundLocationPlugin.TAG, "onRequestPermissionResult")
if (requestCode == REQUEST_PERMISSIONS_REQUEST_CODE) {
when {
grantResults!!.isEmpty() -> Log.i(BackgroundLocationPlugin.TAG, "User interaction was cancelled.")
grantResults[0] == PackageManager.PERMISSION_GRANTED -> service?.requestLocationUpdates()
else -> Toast.makeText(context, R.string.permission_denied_explanation, Toast.LENGTH_LONG).show()
}
}
return true
}

It appears as though the OP's issue is in relation to a completely different flutter package which already has this issue reported here: rekabhq/background_locator#333

closing as not relevant to this codebase
