Flutter 嵌套 JSON 解析

我这里有一个嵌套的 JSON api：

[
  {
    "Employee": {
      "Name": "Michael Jackson",
      "Identification": "881228145031",
      "Company": "Test Corporate",
      "DateOfBirth": "1988-12-28",
      "Entitlements": {
        "GP": {
          "Entitlement": "10000",
          "Utilisation": "500",
          "Balance": "9500"
        },
        "OPS": {
          "Entitlement": "10000",
          "Utilisation": "500",
          "Balance": "9500"
        },
        "IP": {
          "Entitlement": "50000",
          "Utilisation": "17000",
          "Balance": "33000"
        },
        "Dental": {
          "Entitlement": "0.00",
          "Utilisation": "0.00",
          "Balance": "0.00"
        },
        "Optical": {
          "Entitlement": "500",
          "Utilisation": "0.00",
          "Balance": "500"
        },
        "EHS": {
          "Entitlement": "1000",
          "Utilisation": "250",
          "Balance": "750"
        }
      }
    },
    "Dependents": [
      {
        "Name": "Kim",
        "Relationship": "Parent",
        "Entitlements": {
          "GP": {
            "Entitlement": "10000",
            "Utilisation": "500",
            "Balance": "9500"
          },
          "OPS": {
            "Entitlement": "10000",
            "Utilisation": "500",
            "Balance": "9500"
          },
          "IP": {
            "Entitlement": "50000",
            "Utilisation": "17000",
            "Balance": "33000"
          },
          "Dental": {
            "Entitlement": "800",
            "Utilisation": "200",
            "Balance": "600"
          },
          "Optical": {
            "Entitlement": "500",
            "Utilisation": "0.00",
            "Balance": "500"
          },
          "EHS": {
            "Entitlement": "1000",
            "Utilisation": "250",
            "Balance": "750"
          }
        }
      },
      {
        "Name": "Tim",
        "Relationship": "Spouse",
        "Entitlements": {
          "GP": {
            "Entitlement": "10000",
            "Utilisation": "500",
            "Balance": "9500"
          },
          "OPS": {
            "Entitlement": "10000",
            "Utilisation": "500",
            "Balance": "9500"
          }
        }
      }
    ]
  }
]

如您所见，JSON 文件在两个文件中都有相同的嵌套Employee and 家属 called 权利里面有一些地图。

两者的基本模型类Employee and 家属如下面所述：

crm_single_user_model.dart（员工模型）

class SingleUser{

  final String name, identification, company, dob;

  SingleUser({this.name, this.identification, this.company, this.dob});

  factory SingleUser.fromJson(Map<String, dynamic> ujson){

    return SingleUser(
      name: ujson["Name"].toString(),
      identification: ujson["Identification"].toString(),
      company: ujson["Company"].toString(),
      dob: ujson["DateOfBirth"].toString()
    );
  }
}

crm_dependent_list_model.dart（家属模型）

class DependantModel{

  String name;
  String relationship;

  DependantModel({this.name, this.relationship});

  factory DependantModel.fromJson(Map<String, dynamic> depjson){

    return DependantModel(
      name: depjson["Name"].toString(),
      relationship: depjson["Relationship"].toString()
    );
  }
}

我的问题是如何为权利创建模型类？

我似乎无法想出一个解决方案来创建一个地图内有大量地图的模型类。

非常感谢您在此事上的帮助。

尝试看看那个例子

class Product {
  final int id;
  final String name;
  final List<Image> images;

  Product({this.id, this.name, this.images});
}

class Image {
  final int imageId;
  final String imageName;

  Image({this.imageId, this.imageName});
}
