JSON 无法使用 Ferry 包从 GraphQL 查询反序列化数据类型

Question

我有这个 GraphQL 查询：

query QuoteRequests($page: Int!) {
  getQuoteRequestsList(page: $page) {
    vehicle
    body
    licensePlate
    vin
    quality
    currency
    items
  }
}

它生成此示例结果：

{
    "data": {
        "getQuoteRequestsList": [
            {
                "vehicle": "1997 TOYOTA AVALON 4 DR ",
                "body": "Sedan",
                "licensePlate": "RHJ456",
                "vin": "XBGGDFYYREAXVJJJD",
                "quality": [
                    "GENUINO"
                ],
                "currency": "USD",
                "items": [
                    {
                        "uid": "74355f85-5312-9999-8acd-709ceccda00a",
                        "name": "Doble cero que es",
                        "description": "no me interesa",
                        "quantity": 11
                    },
                    {
                        "uid": "66db6fe0-1044-4d58-8454-5e51ab7a313f",
                        "name": "El arenero",
                        "description": "el duende verde",
                        "quantity": 2
                    }
                ]
            },
        ]
    }
}

items 数据是 JSON 类型，当尝试使用 Ferry 包和

获取该数据时

client.request(GQuoteRequestsReq((b) => b..vars.page = 0)).listen((response) => print(response.data.toString()));

我得到一个 Null 结果，但如果我在查询中保留 items，我会得到一个非空结果。如果我运行使用 HTTP 包进行查询，我没有问题。

这是包的错误吗？或者我需要配置什么吗？

谢谢。

这绝对是一个错误，因为如果我尝试在 Flutter 中进行热重载，我会在调试控制台中收到此错误：

Reloaded 1 of 1700 libraries in 860ms.
E/flutter ( 2286): [ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: Deserializing '[__typename, Query, getQuoteRequestsList, [{__typename: GetQuoteRequestsRecor...' to 'GQuoteRequestsData' failed due to: Deserializing '[{__typename: GetQuoteRequestsRecord, uid: 0bf6709f-7ab7-464e-8ee3-6a94e46f05...' to 'BuiltList<GQuoteRequestsData_getQuoteRequestsList>' failed due to: Deserializing '[__typename, GetQuoteRequestsRecord, uid, 0bf6709f-7ab7-464e-8ee3-6a94e46f057...' to 'GQuoteRequestsData_getQuoteRequestsList' failed due to: Deserializing '[{uid: 16870250-5acb-4c23-a7e4-f4e23bbd23ad, name: Doble cero que es, descrip...' to 'GJSON' failed due to: type 'List<dynamic>' is not a subtype of type 'String?' in type cast

很明显它正在获取预期的结果，但它无法正确反序列化，然后它 returns 一个空结果。

有什么解决方法吗？

我试过但我遇到了同样的错误。

就我而言，我遵循了这些步骤，

已安装 built_value 软件包，
编辑了 build.yaml 文件，
运行命令flutter packages pub run build_runner build
