Answer 1

How about your initialized your utils class firts? so you will not got error kotlin.UninitializedPropertyAccessException: lateinit property currentLocation

class Utils (){
companion object {
    lateinit var currentLocation: LatLng
    var vienna= LatLng(-23.5629, -46.6544)
    var markers = ArrayList<Issue>()
}

fun initMyCurrentLocation(loc:LatLang?){
    currentLocation = loc?: vienna
  }
}

in your frag you can used this method like this:

override fun onMapReady(googleMap: GoogleMap) {
//init you currentLocationHere
Utils.initMyCurrentLocation('yourCurrentLocation')
//the rest code.
  val position = if (currentLocation != null) LatLng(currentLocation!!.latitude, currentLocation!!.longitude) else Utils.vienna
    this.map = googleMap
    this.map!!.moveCamera(CameraUpdateFactory.newLatLngZoom(position, 15f)) // Vienna
    getFineLocationPermission()
    this.map!!.setOnMarkerClickListener(this)
    this.map!!.uiSettings.isRotateGesturesEnabled = true
    this.map!!.uiSettings.isZoomGesturesEnabled = true
    this.map!!.setOnInfoWindowClickListener(this)
    this.map!!.setOnMapLongClickListener(this)


}

The problem is here

kotlin.UninitializedPropertyAccessException: lateinit property currentLocation has not been initialized

That happen because your lateinit var currentLocation: LatLng never initialize in init{} block. init{} block for class will call when you create new Instance of that class. But your currentLocation is a variable in companion object , so when you call it that way your class is never created an object and currentLocation will never initialized.

You can fix this by using object instead of class.

object Utils  {
    lateinit var currentLocation: LatLng
    init {
         currentLocation = `...`
    }

}
