How to get bounds after map drag in Here Maps

Question

I am facing a problem to get the map bounds in Here maps after dragend event. I need the new lat,lng to get some items/points within the new changed viewports. I Just want to get the alternatives of google maps map.getBounds().getNorthEast().lat() when the drag ends.

I have tried these methods but none of them returned the lat,lng position of the Northeast and southwest coordinate.


 Heremap.addEventListener('dragend', (ev) => {
                    const target = ev.target;


                   // console.log(map.getViewModel().getLookAtData().bounds);
                    // console.log(map.getBounds());
                    // console.log(target.getViewPort());
                    // console.log(target.getBoundingBox());

                }, false);

Hi, would you please give more detail codes? There is a good example for this https://developer.here.com/api-explorer/maps-js/markers/draggable-marker — , Jul 22 '19 at 02:19

Please see this document:

Here is some snipped code:

map.addEventListener('dragend', (ev) => {
    var bounds = map.getViewModel().getLookAtData().bounds;
});

              var bounds = map.getViewModel().getLookAtData().bounds.getBoundingBox();
              var SWlong = bounds.getLeft();
              var SWlat = bounds.getBottom();
              var NElong = bounds.getRight();
              var NElat = bounds.getTop();

This is my working code to get 4 corner of view port bounding box
