Hello,

I have an event as shown below. How can I check if the added layer is part of a basemap? e.g. world terrain layer, etc.

this.view.on("layerview-create", (event) => {
   // Only recreate model if it's not a basemap change
   this._createModelFromLayers();
   this.render();
})

Theoretically you would get the views "map" and the maps "basemap" and then you have access to the Basemap objects referenceLayers and or baseLayers collection properties, to see if your layer exists in those collections.
