Hi i am trying to add muliple picture marker symbol in my app where x and y coordinates of different type of markers come from db like low signal and high signal

Now i am trying to add it in my map like below but it doesn't show up with markers

I see an issue in your addMarker function. Point's spatialReference property expects a SpatialReference object, but the way you've got it, it passes in a json of wkid: 4326. Try instead:

return ArcGISRuntimeEnvironment.createObject("Point",{"x":172.49307355493,"y": -43.4810759934974, "spatialReference": SpatialReference.createWgs84() });


Or

const sr = ArcGISRuntimeEnvironment.createObject(“SpatialReference”, { “wkid”: 4326};

return ArcGISRuntimeEnvironment.createObject("Point",{"x":172.49307355493,"y": -43.4810759934974, "spatialReference": sr });‍‍‍‍‍‍‍‍
