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

请帮忙。 提前致谢。

【问题讨论】：

我找到了一个解决方案，只需要更改项目环境即可。如果要更新旧项目。环境：sdk：">=2.12.0

【参考方案1】：

改变

环境：sdk: ">=2.X.0

到

环境：sdk: ">=2.12.0

【讨论】：

除了这样做没有别的选择了吗？我不想将我的项目升级为强制空安全。
