Basemap Human Geography Dark Map well known ID

[DavideLimosani]

Hello, 

I can't find the wellKnownID for basemap "Human Geography Dark Map".

It's automatically added in the basemapgallery widget but I need to load only a subset of all basemaps:

    basemapGallery = new BasemapGallery({
            view: app.activeView,
            container: document.createElement("div"),
            source: [Basemap.fromId("satellite"), Basemap.fromId("osm"), Basemap.fromId("hybrid"), Basemap.fromId("topo"), Basemap.fromId("dark-gray"), Basemap.fromId("gray"), Basemap.fromId("???human-dark-gray???")],
            activeBasemap: basemap
        });

Can someone help me?

Thank you,

Davide

Doesn't look like the human basemaps are named basemaps in the API.

You can find the basemap webmap ids by searching
