Hello.
Im trying to developing a custom widget for my WAB APP and im following the steps in this website Naming conventions—Web AppBuilder for ArcGIS (Developer Edition) | ArcGIS for Developers
1.- I understood that each widget has some files that has to be in there , like:
html file
css file
js.file
and in the app.config when i want to add the custom widget or anyone that i want, i have to put this:
{ "label": "demo", "uri": "widgets/Demo/Widget" } in the widgetPool->widgets.
Idk if im kinda lost or im doing something wrong, but when i zip my app to upload it to the WAB to see if i can see my demo widget, i have the error with it.
