飞镖文件

   part 'api_service.g.dart';

@RestApi(baseUrl: "https://example.com/")
abstract class ApiService {
  factory ApiService(Dio dio, {String baseUrl}) = _ApiService;

  static ApiService create() {
    final dio = Dio();
    dio.interceptors.add(PrettyDioLogger());
    dio.interceptors.clear();
    return ApiService(dio);
  }

  @POST("project/{id}")
  Future<String> addProject(@Path() String id,
      @Body() Map<String, dynamic> body,);
}

我得到的错误
