getLngLat method
Get the marker's geographical location.
The longitude of the result may differ by a multiple of 360 degrees from the longitude previously
set by setLngLat
because Marker
wraps the anchor longitude across copies of the world to keep
the marker on screen.
@returns {LngLat}
Implementation
LngLat getLngLat() => LngLat.fromJsObject(jsObject.getLngLat());
