I've successfully:
1) created a map in AGO,
2) created a WAB app on AGO that points at map in #1
3) downloaded the "WAB Developer Addition"
4) configured a local version of the app in #2 by pasting the js code into config.json
5) ran the app on our local webserver
Using the ArcGIS JS API, how can I do things like the following in my locally hosted web app:
-- add a feature layer?
-- dynamically create and change labels when the map is panned or zoomed?
-- dynamically change symbology of feature layers?
-- programmatically toggle layer visibility?
Is that possible when using WAB? If so, where do I put the code to that?
