        if (location != null) {
            currentLocation = location
            val currentLatLng = LatLng(location.latitude, location.longitude)
            val currentAddress = getAddress(location.latitude, location.longitude)
            Log.d("TAG", "klagenfurt : ${currentAddress}")
            retrofitOneCallResponse(location.latitude, location.longitude, currentAddress)
            dataService.getFavorites(this)

        }


    }
    if (ActivityCompat.checkSelfPermission(
            requireContext(), android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED)
    {
        ActivityCompat.requestPermissions(
            requireActivity(),
            arrayOf(android.Manifest.permission.ACCESS_FINE_LOCATION),
            MapViewFragment.LOCATION_PERMISSION_REQUEST_CODE
        )

    }

Create one method like this.

private fun getLocation(){
fusedLocationClient.lastLocation.addOnSuccessListener(requireActivity()) { location ->
        if (location != null) {
            currentLocation = location
            val currentLatLng = LatLng(location.latitude, location.longitude)
            val currentAddress = getAddress(location.latitude, location.longitude)
            Log.d("TAG", "klagenfurt : ${currentAddress}")
            retrofitOneCallResponse(location.latitude, location.longitude, currentAddress)
            dataService.getFavorites(this)
        }else{
         getLocation()
        }
    }
}

then from here

if (ActivityCompat.checkSelfPermission(
            requireContext(), android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED)
    {
        requestPermissions(
            arrayOf(android.Manifest.permission.ACCESS_FINE_LOCATION),
            MapViewFragment.LOCATION_PERMISSION_REQUEST_CODE
        )
    }else{
      getLocation()
}


override fun onRequestPermissionsResult(requestCode: Int, permissions: Array<out String>, grantResults: IntArray): Unit {
      if(requestCode==MapViewFragment.LOCATION_PERMISSION_REQUEST_CODE){
          if(grantResults[0]==PackageManager.PERMISSION_GRANTED){
              getLocation();
          }
      }
}

Also, override the onRequestPermissionsResult in the fragment. and check if permission granted the call getLocation() .
