I am in the process of modifying the BasemapGallery Widget in WAB 1.2 Developer edition so that it might dynamically update the array of available basemaps based on communication with a separate controller widget.
I am getting tripped up on something that should be easy. Namely, the syntax for providing a basemap array.
Does anyone have an example of the JSON syntax that would be used to manually configure the config.json file for the BasemapGallery widget?
Thanks for the help!
