Add legend info for map layer

Question

I am creating a number of kml layers and adding them async to my map. The problem is, is that I can't figure out how to create their legend info so that they can be displayed on my legend to the map. I want to do something like this, but can't figure out how to get anything to work at all. i know I need to add to the legendinfos of the layer or the map itself, but hit a roadblock. This append below doesn't work at all, but shows what I am trying to do. var newKMLLayer = ArcGISRuntimeEnvironment.createObject("KmlLayer", { dataset: newKMLDataset, id: kmlLayer, description: inName, layerId: "LayerID", name: inName, maxScale: 0, minScale: 0, visible: false }); newKMLLayer.legendInfos.append({ "layerName": inName, "symbolURL": "URL" }) mapViewFieldSelected.map.operationalLayers.append(newKMLLayer)‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

You'll probably need to handle KML Layers as a special case in your TOC, as they function differently than most other layers. The concept of LegendInfos doesn't really apply to them. TO build a TOC, you will need to go down the the node hierarchy (starting from the dataset rootNodes and using the container or networklink childNodes to go down) and use the KmlNode.UXIcon + KmlNode.Name (for example) to create a TOC entry
