[BUG] [Dart] Documentation for auth uses defaultApiClient.getAuthentication<ApiKeyAuth> but no such methods exists

[0xNF]

Description

See: https://github.com/OpenAPITools/openapi-generator/blob/df05e6f4bc6265ba4de801ba306f75dd7278e119/samples/openapi3/client/petstore/dart2/petstore_client_lib/doc/UserApi.md

import 'package:openapi/api.dart';
// TODO Configure API key authorization: api_key
//defaultApiClient.getAuthentication<ApiKeyAuth>('api_key').apiKey = 'YOUR_API_KEY';
// uncomment below to setup prefix (e.g. Bearer) for API key, if needed
//defaultApiClient.getAuthentication<ApiKeyAuth>('api_key').apiKeyPrefix = 'Bearer';

But the ApiClient class has no such method. Here are the available methods on the object:

invokeAPI()
addDefaultHeader()
deserializeAsync()
serializeAsync()
deserialize()
serialize()

There's a .authentication object but the interface only has a single void applyToParams(List<QueryParam> queryParams, Map<String, String> headerParams); function.

Consequently, I don't know what the canonical way to do auth, and specifically Cookie Auth is.

Facing the same issue.

This method used to exist, but since we've updated to the newer version with dart null-safety its not there anymore. We are not able to update the auth token anymore. Any one got a workaround for this?

@0xNF In my case, HttpBearerAuth is working fine with this code: (openapi-generator-cli 6.0.1)

  var authentication = HttpBearerAuth();
  authentication.accessToken = initialToken;
  var client = ApiClient(
    basePath: 'https://.../api/v2',
    authentication: authentication,
  );
  final api = SystemApi(client);

ApiKeyAuth seems supporting cookie. The code will be like this:

  var authentication = ApiKeyAuth('cookie', 'paramName');
  authentication.apiKey = 'YOUR_API_KEY';
  // authentication.apiKeyPrefix = 'Bearer';
  var client = ApiClient(
    authentication: authentication,
  );
  final api = UserApi(client);
