Get User Model Array List - flutter

Question

I need to get payments array in GetUserModel it returns from nodeJs api with database information
I get with this:
List? payments
Future getCurrentUser() async {
var loginDetails = await SharedService.loginDetails();
email = loginDetails?.data.email;
GetUserRequestModel model = GetUserRequestModel(email: email!);
var currentUserInfo = await APIService.getUserInfo(model);
balance = currentUserInfo.data?.balance;
payments = currentUserInfo.data?.payments; //does not working
print(payments)
}
currentUserInfo gives me everythings but I couldnt get payments array. print(payments)
gives me "Instant of payments" output how can I get payments array properly?
This is UserresponseModel:
import 'dart:convert';
GetUserResponseModel getUserResponseModelJSON(String str) =>
GetUserResponseModel.fromJson(json.decode(str));
class GetUserResponseModel {
GetUserResponseModel({
required this.message,
required this.data,
});
late final String message;
late final Data? data;
GetUserResponseModel.fromJson(Map<String, dynamic> json) {
message = json['message'];
data = (json['data'] != null ? Data.fromJson(json['data']) : null);
}
Map<String, dynamic> toJson() {
final _data = <String, dynamic>{};
_data['message'] = message;
_data['data'] = data?.toJson();
return _data;
}
}
class Data {
Data({
required this.username,
required this.email,
required this.balance,
required this.date,
required this.payments,
required this.id,
});
late final String username;
late final String email;
late final int balance;
late final String date;
late final List<Payments> payments;
late final String id;
Data.fromJson(Map<String, dynamic> json) {
username = json['username'];
email = json['email'];
balance = json['balance'];
date = json['date'];
payments =
List.from(json['payments']).map((e) => Payments.fromJson(e)).toList();
id = json['id'];
}
Map<String, dynamic> toJson() {
final _data = <String, dynamic>{};
_data['username'] = username;
_data['email'] = email;
_data['balance'] = balance;
_data['date'] = date;
_data['payments'] = payments.map((e) => e.toJson()).toList();
_data['id'] = id;
return _data;
}
}
class Payments {
Payments({
required this.paymentCost,
required this.paymentDate,
required this.id,
});
late final int paymentCost;
late final String paymentDate;
late final String id;
Payments.fromJson(Map<String, dynamic> json) {
paymentCost = json['paymentCost'];
paymentDate = json['paymentDate'];
id = json['_id'];
}
Map<String, dynamic> toJson() {
final _data = <String, dynamic>{};
_data['paymentCost'] = paymentCost;
_data['paymentDate'] = paymentDate;
_data['_id'] = id;
return _data;
}
}
And this is the getUserInfo:
static Future<GetUserResponseModel> getUserInfo(
GetUserRequestModel model) async {
var loginDetails = await SharedService.loginDetails();
Map<String, String> requestHeaders = {
'Content-Type': 'application/json',
'Authorization': 'Basic ${loginDetails!.data.token}'
};
var url = Uri.http(Config.apiURL, Config.getUserInfoAPI);
var response = await client.post(
url,
headers: requestHeaders,
body: jsonEncode(model.toJson()),
);
return getUserResponseModelJSON(response.body);
}

Answer 1

So I think you are looking to print the payments data.
In the payments class you should add
#override
String toString() {
return "";
// Return how you want to print the data. Here you could add for example the JSON output.
}
So the class will look like this
class Payments {
Payments({
required this.paymentCost,
required this.paymentDate,
required this.id,
});
late final int paymentCost;
late final String paymentDate;
late final String id;
Payments.fromJson(Map<String, dynamic> json) {
paymentCost = json['paymentCost'];
paymentDate = json['paymentDate'];
id = json['_id'];
}
Map<String, dynamic> toJson() {
final _data = <String, dynamic>{};
_data['paymentCost'] = paymentCost;
_data['paymentDate'] = paymentDate;
_data['_id'] = id;
return _data;
}
#override
String toString() {
return "${this.paymentCost!} : ${this.paymentDate!} : ${this.id!}";
}
}
I haven't tested this code.
