src/schemas/area_schemas.py line 36 at r1 (raw file):

    @classmethod
    def from_dict(cls, data: Dict[str, Any]) -> "Area":

How about we import:
from future import annotations

And then use Area without ""?

That seems cleaner. Do you agree? If so, can you please change all instances where "" is used?

Code quote:

"Area"
