How to add a marker?

We need to use a Marker object to work with markers. A new marker can be added with the following method:

GoogleMap.addMarker()

This code takes the parameter as the MarkerOptions object. The latitude and longitude are set for the map using a LatLng object. The latitude and longitude can also be set as follows

MarkerOptions().position()
