Hello Nathan
I would like to use the add shape file widget in my WAB project; however I am experience some difficulty incorporating this widget due to the fact I am working within a corporate network in highly secured development environment.
In efforts to trouble shoot my issue, it looks like line #68 of your code sets the shape files to pull from www.arcgis.com. Should this line be changed to the classified equivalent of the same web site. I tried changing line #68 to read -- var portalUrl = "https://portal.Xxx.cloud.XX.gov"; which is the classified equivalent of www.arcgis.com
Is this a good place to start trouble shooting? What other parts of this widget code should I look into changing?
