You have links for sample apps in both 4.x and 3.x versions of the JS API. Are you just unable to implement this in your app?

There is difference in functionality but I need functionality exactly like 3.x version not 4.x version .my organization is using 4.x version so can't switch to 3.x version .

Can you clarify what you want the 4.x version of the overview map to do differently?

I'm not able to develop a working solution for this but I think it should be possible. The extent indicator in the overview map is just a graphic so you should be able to modify it. Here's a solution that modifies a static graphic in a map view. I was also able to get the cursor to change when mousing over the overview extent graphic. You can use this on the 4.x example from above.

// get screenpoint from mapView's pointer-move event mapView.on("pointer-move", function(event) { mapView.hitTest(event, {include: mapView.graphics}).then(function(response) { // check if a feature is returned from the hurricanesLayer if (response.results.length) { document.getElementById("overviewDiv").style.cursor = "move"; const graphic = response.results[0].graphic; // do something with the graphic } else { document.getElementById("overviewDiv").style.cursor = "default"; } }); });

Be sure to post back here if you're able to build a working solution! 😀

The above link draws a point, line and polygon on map which is not related to overviewmap could please share the correct link.

Yes, because it's just mashing up two existing sample apps. Just get rid of the point and line graphics to test with the polygon.

I'm sorry, I don't have the time and ability to develop a solution for this in a reasonable amount of time. You're going to have to get creative on your own.
