hello, is there a tutorial or any solution to begin WAB for developers ?
Sure look here:
Create a custom in-panel widget—Web AppBuilder for ArcGIS (Developer Edition) | ArcGIS for Developers
Thank you Robert
If just starting out, I would check out my blogs
Tips and Observations for getting Web AppBuilder - Developer Edition Installed (updated 8/26/2018)
Web AppBuilder Developer Edition - Resource List (updated 5/13/2018)
and this detailed doc by Tapas
Installing Robert’s Enhanced Search Widget for the Web AppBuilder
and of course the geonet sites Web AppBuilder Custom Widgets Web AppBuilder Custom Themes
also, there are short videos available to watch at http://videos.esri.com I'll edit with better link in a minute.
There are filtered links on the resource page.
also, though not complete, I started pulling training resource into a separate blog
