Kotlin with Map ( Marker Not showing)

Question

Hello I'm trying to implements Google Maps in kotlin, but in these code my getMapAsyncis not getting called, the maps shows perfectly but the marker doesn't show up

    var mapFragment : SupportMapFragment?=null
    mapFragment= fragmentManager.findFragmentById(R.id.map) as SupportMapFragment?
    mapFragment?.getMapAsync { 
        val sydney = LatLng(22.30, 73.20)
        mMap!!.addMarker(MarkerOptions().position(sydney).title("Marker in Sydney"))
        mMap!!.moveCamera(CameraUpdateFactory.newLatLng(sydney))


        Toast.makeText(activity,"dfgdg",Toast.LENGTH_LONG).show() }

Answer 1

1. You are using the wrong map instance.
2. Sydney lat lng are -33.8479731,150.6517908

mapFragment?.getMapAsync { 

    map ->  // <- this is the map that you got async not mMap            
        val sydney = LatLng(-33.8479731, 150.6517908)
        map.addMarker(...
        map.moveCamera(...
}
