Put a marker of a person from firebase on a map
I am developing an app and I cant figure out how to put a marker to the location of a person from my firebase. I have tried this:
var ocherednyara: LatLng
if(document.data.getValue("online") as Boolean){
ocherednyara = LatLng((document.data.getValue("latitude") as Double), (document.data.getValue("longitude") as Double))
placeMarkerOnMap(ocherednyara)...
