Разбор флаттера. JSON из остальных API

Вот как выглядит JSON:

Я написал эти классы, но я не совсем знаю, что делать дальше:

class Price {
  final String total;

  Price({this.total});

  factory Price.fromJson(Map<String, dynamic> json) {
    return Price(
      total: json['total'],
    );
  }
}
class Links {
  final String flightDates;
  final String flightOffers;

  Links({this.flightDates, this.flightOffers});

  factory Links.fromJson(Map<String, dynamic> json) {
    return Links(
      flightDates: json['flightDates'],
      flightOffers: json['flightOffers'],
    );
  }
}
class Data {
  final String type;
  final String origin;
  final String destination;
  final String departureDate;
  final String returnDate;
  final Price price;
  final Links links;

  Data({this.type, this.origin,this.destination,this.departureDate,this.returnDate,this.price,this.links});

  factory Data.fromJson(Map<String, dynamic> parsedJson) {
    return Data(

        links: Links.fromJson(parsedJson['links'],));}}

class Links2 {
  final String total;

  Links2({this.total});

  factory Links2.fromJson(Map<String, dynamic> json) {
    return Links2(
      total: json['self'],
    );
  }
}
class Default {

      defaults: Default.fromJson(json['defaults']),
    );
  }
}


class All {
  final List<Data> data;
  final Meta meta;

  All(
      {this.data, this.meta});
  static List<Data> parseData(dataJson) {
    var list = dataJson['data'] as List;
    List<Data> dataList =
    list.map((data) => Data.fromJson(data)).toList();
    return dataList;
  }
  factory All.fromJson(Map<String, dynamic> json) {
    return All(
      meta: Meta.fromJson(json['meta'],),
      data: parseData(json),
    );
  }
}


Future<String> loadAllFromAssets() async {
  return await rootBundle.loadString('json/all.json');
}

Future loadAll() async {
  String jsonString = await loadAllFromAssets();
  final jsonResponse = json.decode(jsonString);
  All all = new All.fromJson(jsonResponse);
  print('Images: ${all.data[0].type}');
}

И нужно ли мне все это анализировать? Или есть способ использовать только данные.

Answer 1

Существует веб-сайт с именем: QuickType.io ссылка: https://app.quicktype.io. поэтому в зависимости от вашего json я сделал модель, показанную ниже:

// To parse this JSON data, do
//
//     final data = dataFromJson(jsonString);

import 'dart:convert';

Data dataFromJson(String str) => Data.fromJson(json.decode(str));
