I have created an application with DartTheme using the webappbuilder embedded with Arcgis Portal 10.7.
When i download the application and host it on IIS then try to change the styling it doesn't point to the correct file such as
https://myapplication/themes/DartTheme/widgets/DartController/css/style.css
Also widget.html is missing in https://myapplication/themes/DartTheme/widgets/DartController/widget.html
When i try to check for styling it just shows as <style></style> in Elements -> Styles
Whereas i don't find this issue when working with standalone WebAppBuilder.
Please let me know if anyone have faced this issue.
