I have a folder "dashboards". Inside that i'm trying to create applications using "ng g application promotions". But it creates inside projects/promotions. I also tried using "--flat". But it still creates folder. How to create without folder?
In your angular.json, change the property value of newProjectRoot from projects to dashboards.
"newProjectRoot": "dashboards",
If you create any new application in the workspace, then the app will be generated inside the dashboards folder.
