1) first put json code to any convert website ex:
[JSON to Darthttps://javiercbk.github.io ›][1]
it will give like this output
class Autogenerated {
int? code;
List<Result>? result;
String? status;
Autogenerated({this.code, this.result, this.status});
Autogenerated.fromJson(Map<String, dynamic> json) {
code = json['code'];
if (json['result'] != null) {
result = <Result>[];
json['result'].forEach((v) {
result!.add(new Result.fromJson(v));
});
}
status = json['status'];
}
Map<String, dynamic> toJson() {
final Map<String, dynamic> data = new Map<String, dynamic>();
data['code'] = this.code;
if (this.result != null) {
data['result'] = this.result!.map((v) => v.toJson()).toList();
}
data['status'] = this.status;
return data;
}
}
class Result {
int? id;
int? projectId;
String? projectName;
int? userId;
String? userName;
Result(
{this.id, this.projectId, this.projectName, this.userId, this.userName});
Result.fromJson(Map<String, dynamic> json) {
id = json['id'];
projectId = json['project_id'];
projectName = json['project_name'];
userId = json['user_id'];
userName = json['user_name'];
}
Map<String, dynamic> toJson() {
final Map<String, dynamic> data = new Map<String, dynamic>();
data['id'] = this.id;
data['project_id'] = this.projectId;
data['project_name'] = this.projectName;
data['user_id'] = this.userId;
data['user_name'] = this.userName;
return data;
}
}
--------------------------------------------------------------------------------------
and change that code like this format for easy use
***get_client.dart***
import 'package:json_annotation/json_annotation.dart';
part 'get_client.g.dart';
@JsonSerializable(
explicitToJson: true,
)
class ClientModel {
@JsonKey(name: "address1")
String? address1;
@JsonKey(name: "city")
int? city;
@JsonKey(name: "city_name")
String? cityName;
@JsonKey(name: "country")
int? country;
@JsonKey(name: "country_name")
String? countryName;
@JsonKey(name: "email")
String? email;
@JsonKey(name: "first_name")
String? firstName;
@JsonKey(name: "gender")
String? gender;
@JsonKey(name: "id")
int? id;
@JsonKey(name: "last_name")
String? lastName;
@JsonKey(name: "mobile_no")
String? mobileNo;
@JsonKey(name: "password")
String? password;
@JsonKey(name: "pincode")
String? pincode;
@JsonKey(name: "role")
int? role;
@JsonKey(name: "role_name")
String? roleName;
@JsonKey(name: "state")
int? state;
@JsonKey(name: "state_name")
String? stateName;
ClientModel(
{this.address1,
this.city,
this.cityName,
this.country,
this.countryName,
this.email,
this.firstName,
this.gender,
this.id,
this.lastName,
this.mobileNo,
this.password,
this.pincode,
this.role,
this.roleName,
this.state,
this.stateName});
factory ClientModel.fromJson(Map<String, dynamic> map) =>
_$ClientModelFromJson(map);
Map<String, dynamic> toJson() => _$ClientModelToJson(this);
}

after run build runner cmd in terminal
***flutter pub run build_runner build***
then it will create the following output file
// GENERATED CODE - DO NOT MODIFY BY HAND
part of 'get_client.dart';
// **************************************************************************
// JsonSerializableGenerator
// **************************************************************************
ClientModel _$ClientModelFromJson(Map<String, dynamic> json) => ClientModel(
address1: json['address1'] as String?,
city: json['city'] as int?,
cityName: json['city_name'] as String?,
country: json['country'] as int?,
countryName: json['country_name'] as String?,
email: json['email'] as String?,
firstName: json['first_name'] as String?,
gender: json['gender'] as String?,
id: json['id'] as int?,

);
Map<String, dynamic> _$ClientModelToJson(ClientModel instance) =>
<String, dynamic>{
'address1': instance.address1,
'city': instance.city,
'city_name': instance.cityName,
'country': instance.country,

'pincode': instance.pincode,
'role': instance.role,

};
after we can use like this in repository file
static Future<dynamic> getAllClients(int id) async {
String url = "${HttpUrls.clientList}/${0}";
Response response = await dio.get(url);
if (response.statusCode == 200) {
List<ClientModel> clientLists = (response.data['result'] as List)
.map((eachItem) => ClientModel.fromJson(eachItem))
.toList();
print(clientLists.toString());
if (clientLists.isNotEmpty) {
return clientLists;
}
} else {
BaseResponse baseResponse =
BaseResponse.fromJson(response.data as Map<String, dynamic>);
return baseResponse;
}
}
