Generate REST API and OpenAPI documentation for your Flask project.
Flask OpenAPI3 is a web API framework based on Flask. It uses Pydantic to verify data and automatic
generation of interaction documentation: Swagger, ReDoc and RapiDoc.
pyyaml is used to output the OpenAPI document in yaml format.
asgiref allows views to be defined with async def and use await.
