The getter 'MediaType' isn't defined for the class
Try correcting the name to the name of an existing getter, or defining a getter or field named 'MediaType'.
        contentType: MediaType.parse('application/json'),

To Reproduce Steps to reproduce the behavior:

  @POST("/my/endpoint")

@sbatezat Import MediaType manually as a workaround

[sbatezat]

Thanks, it's working by importing manually http_parser.

import 'package:http_parser/http_parser.dart';

It's a workaround, as you said, so I keep this issue open waiting for a robust fix!

@sbatezat The problem here is that MediaType is not imported by default if you are not using it in the template for the api, since we can't add imports in part files, the only solution I see is to expose http_parser's MediaType through export 'package:http_parser/http_parser.dart' show MediaType in http.dart, as that is always imported in template files. Is this acceptable? It would mean an extra dependency. I don't see any other way we could guarantee the import, but I am not an ace when it comes to working with code_gen
