`Authorization classes are not loaded` warning.

[taaaf11]

Today, I was trying to create a custom control to be added to this repo. I looked into the code already in the repo. There, I saw

import flet_core as ft

I created main.py file in the cloned directory of flet_contrib, it did not give any warning.

But when I use this line in code of the control and execute code in main.py, it gives me warning:

Authorization classes are not loaded, using fake implementations.
