Deserializing JSON data in Flutter - json

Question

the JSON data in question is https://api.aladhan.com/v1/calendarByCity?city=London&country=United%20Kingdom&method=8&month=06&year=2021
List <PrayerTimesPerDay> prayerList; // Read the contents of nested List
// the bottom section is pretty inaccurate afaik
factory PrayerTimesPerDay.fromJson(Map<String, dynamic> json) {
List timings = json["data"];
return PrayerTimesPerDay(
day: json['gregorian']['weekday']['en'],
fajr: json['Fajr'],
zuhr: json['Dhuhr'],
asr: json['Asr'],
maghrib: json['Maghrib'],
isha: json['sha'],
);
}
So my intention is to read the timings and the day into a class called PrayerTimesPerDay which had the following variables
final String day;
final String fajr;
final String zuhr;
final String asr;
final String maghrib;
final String isha;
my concern is, I dont really understand how be able to convert such a kind of data into these variables, I manage to extract them as List in my async function and able to print somedata from it, and even planned in making a for loop(which didnt workout) that adds them into a list.
would be appreciated if there was an explaination

Answer 1

SalamoAlikom brother. Here's how I will go about it.
factory PrayerTimesPerDay.fromJson(Map<String, dynamic> json) {
var data = json["data"];
var data_00 = data[0]; //<-- you could loop over here to get all the data!!!
return PrayerTimesPerDay(
day: data_00['date']['gregorian']['weekday']['en'],
fajr: data_00[timings]['Fajr'],
zuhr: data_00[timings]['Dhuhr'],
asr: data_00[timings]['Asr'],
maghrib: data_00[timings]['Maghrib'],
isha: data_00[timings]['sha'],
);
}
this might work however I would strongly recommend code generation as mentioned in the official documentation. That will require you to architect your objects so that they can be easily converted from JSON to play dart object.

Here is a full Model class you can read and understand. It took too much time but I appreciate your question.
You just copy the and save it in a separate file like model.dart:
// To parse this JSON data, do
//
// final welcome = welcomeFromMap(jsonString);
import 'dart:convert';
class Welcome {
Welcome({
this.code,
this.status,
this.data,
});
final int code;
final String status;
final List<Datum> data;
factory Welcome.fromJson(String str) => Welcome.fromMap(json.decode(str));
String toJson() => json.encode(toMap());
factory Welcome.fromMap(Map<String, dynamic> json) => Welcome(
code: json["code"] == null ? null : json["code"],
status: json["status"] == null ? null : json["status"],
data: json["data"] == null ? null : List<Datum>.from(json["data"].map((x) => Datum.fromMap(x))),
