Please provide a minimal reproducible example.

Please provide a minimal reproducible example.

I was working on it, and then tried another way to fix the issue and found it.
The StreamBuilder, at the start, always returned an empty list before returning the real value for some reason, and because of my code, with an empty list the controller had no listview to connect to.
I found a way to fix the issue.
Sorry for bothering you
