You can use app.quicktype.io or any other online sites for parsing your model so fast. Otherwise you need to write manually.
// To parse this JSON data, do
//
// final data = dataFromJson(jsonString);
import 'dart:convert';
Data dataFromJson(String str) => Data.fromJson(json.decode(str));
String dataToJson(Data data) => json.encode(data.toJson());
class Data {
Data({
this.data,
this.message,
this.status,
});
DataClass data;
String message;
int status;
factory Data.fromJson(Map<String, dynamic> json) => Data(
data: DataClass.fromJson(json["data"]),
message: json["message"],
status: json["status"],
);
Map<String, dynamic> toJson() => {
"data": data.toJson(),
"message": message,
"status": status,
};
}
class DataClass {
DataClass({
this.address,
this.cityId,
this.cityName,
this.companyName,
this.creditDays,
this.cusotmerId,
this.email,
this.gstNo,
this.isApproved,
this.lat,
this.long,
this.mobile,
this.pincode,
this.route,
this.stateId,
this.stateName,
this.uniqueNumber,
});
String address;
String cityId;
String cityName;
String companyName;
String creditDays;
String cusotmerId;
String email;
String gstNo;
String isApproved;
String lat;
String long;
String mobile;
String pincode;
String route;
String stateId;
String stateName;
String uniqueNumber;
factory DataClass.fromJson(Map<String, dynamic> json) => DataClass(
address: json["Address"],
cityId: json["CityID"],
cityName: json["CityName"],
companyName: json["CompanyName"],
creditDays: json["CreditDays"],
cusotmerId: json["CusotmerID"],
email: json["Email"],
gstNo: json["GSTNo"],
isApproved: json["IsApproved"],
lat: json["Lat"],
long: json["Long"],
mobile: json["Mobile"],
pincode: json["Pincode"],
route: json["Route"],
stateId: json["StateID"],
stateName: json["StateName"],
uniqueNumber: json["UniqueNumber"],
);
Map<String, dynamic> toJson() => {
"Address": address,
"CityID": cityId,
"CityName": cityName,
"CompanyName": companyName,
"CreditDays": creditDays,
"CusotmerID": cusotmerId,
"Email": email,
