To Reproduce Steps to reproduce the behavior:

Expected behavior The extension generates several Dart models.

Version v2.2.0

Json

{
    "services": [],
    "address": {
        "city": {
            "name": "New York"
        }
    }
}

Additional context The problem its not consistent with empty lists. This specific one happens when there's an empty list and a 2 level nested JSON.
