【问题描述】：

IN this you can find the error when json is converted当我使用 https://javiercbk.github.io/json_to_dart/ 将下面的 json 转换为 dart 时，它说“生成的 Dart 代码无效”。我正在使用未来的构建器在用户界面中显示响应。 当我注释掉“状态”类时，错误发生但没有显示响应。

【问题讨论】：

您使用的是空安全吗？

noo ，这与空安全无关。在线将json转换为对象时会出现此问题

【参考方案1】：

我不知道这是否适合你，但它有效，我改变了这个：

"state": [
      [
           "...state name...",
           "...2 digit state code..."
                                  ]
                              ]

到这里：

"state": [
             "...state name...",
             "...2 digit state code..."
             ]
                              

而且它没有显示无效的飞镖代码消息

是的，错误消失了，bt im nt 得到响应 json
