Provides the logic for the Attribution widget. Displays attribution text for the layers in a map. The text displayed for the layers is either a list of data providers or sources as defined in the layer's custom attribution data, or the copyright text. The attribution is automatically updated based on layer visibility and map extent.
Esri requires that when you use an ArcGIS Online basemap in your app, the map must include Esri attribution and you must be licensed to use the content. For detailed guidelines on working with attribution, please visit the official attribution in your app documentation. For information on terms of use, see the Terms of Use FAQ.
