flutter - 具有相同字段名称的非常​​复杂的 Json

问题描述

我的同事是后端开发的响应，这是 API 响应的示例之一。
我想知道如何将其与地图分开？
而且有同名，我很难处理。JSON 到 Dart 生成的代码也会有相同名称的错误案例。
有没有其他解决方案来处理这个 Json？

解决方案

如果你可以共享 Dart 模型，那么使用 json_serializable 包。那会让事情变得更容易。但...

...如果您必须接受您的同事开发的 JSON 响应并且您无法共享从/转换为 Json 的模型，则一种替代方法是使用https://app.quicktype.io/

我输入了你的 JSON 响应，生成的 Dart 代码至少乍一看似乎是合法的。

该代码生成的示例：

factory ComplexJson.fromJson(Map<String, dynamic> json) => ComplexJson(
    formId: json["formId"],
    formTypeId: json["formTypeId"],
    formTemplateId: json["formTemplateId"],
    version: json["version"],
    history: historyValues.map[json["history"]],
    refNum: json["refNum"],
    dateOfAcceptance: json["dateOfAcceptance"],
    dateOfReacceptance: json["dateOfReacceptance"],
    blockId: json["blockId"],
    floorId: json["floorId"],
    flatId: json["flatId"],
    isPublic: historyValues.map[json["isPublic"]],
    locationId: json["locationId"],
    fromFloorId: json["fromFloorId"],
    toFloorId: json["toFloorId"],
    elevationId: json["elevationId"],
