#3681 [BUG] Flytekit type hints are ignored by mypy Issue created by tekumara ### Describe the bug Flytekit type hints are ignored by mypy because flytekit does not have a

py.typed

marker as per PEP 0561 ### Expected behavior Usage of flytekit is checked against its types. ### Additional context to reproduce Given from typing import Dict, List, NamedTuple from flytekit import task class OpenFlightsData(NamedTuple): routes: List[Dict[str, str]] airlines: Dict[str, str] airports: Dict[str, Dict[str, str]] @task() def extract_reference_data() -> OpenFlightsData: return OpenFlightsData( routes=[{"MAO": "CIZ"}], airlines={"0B": "Blue Air"}, airports={"AAA": {"lat": "1", "lon": "2"}} ) Then when running mypy 1.3.0:
