"WORKAROUND for sending class as request body in `multipart/form-data`" is missing path parameter

[rperne]

Hi there, still great work, thank you so much.

in v3.8 or v4.0, we have noticed a missing path parameter transmission when multi/part data is involved
api_client_generator.dart has a "// WORKAROUND for sending class as request body in multipart/form-data"

but when a path parameter is given,

extension FormDataClientX on FormDataClient {
  Future<HttpResponse<FormData>> updateDataById({
    required FormData requestBody,
    @Path("id") required String id,
    @Extras() Map<String, dynamic>? extras,
    @CancelRequest() CancelToken? cancelToken,
    @SendProgress() ProgressCallback? onSendProgress,
    @ReceiveProgress() ProgressCallback? onReceiveProgress,
  }) {
    return updateDataById_(
      requestBody: requestBody.toJson(),
      extras: extras,
      cancelToken: cancelToken,
      onSendProgress: onSendProgress,
      onReceiveProgress: onReceiveProgress,
    );
  }
}

the internal method has the id parameter

  @PUT("/formData/{id}")
  @MultiPart()
  Future<HttpResponse<FormData>> updateDataById_({
    @Part() required Map<String, dynamic> requestBody,
    @Path("id") required String id,
    @Extras() Map<String, dynamic>? extras,
    @CancelRequest() CancelToken? cancelToken,
    @SendProgress() ProgressCallback? onSendProgress,
    @ReceiveProgress() ProgressCallback? onReceiveProgress,
  });

we can see that the internal call is missing the required id parameter
