Flutter 嵌套 JSON 解析

Question

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 文件在员工和家属中具有相同的嵌套，称为权利，并且其中包含一些映射。

员工和家属的基本模型类如下：

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？

我似乎无法想出在地图内创建具有大量地图的模型类的解决方案。

非常感谢您在这件事上的帮助。

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});
}
