我已经写了这些类(class)，但是我不知道下一步该怎么做:
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(
type: parsedJson['type'],
origin: parsedJson['origin'],
destination: parsedJson['destination'],
departureDate: parsedJson['departureDate'],
returnDate: parsedJson['returnDate'],
price: Price.fromJson(parsedJson['price'],),
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 {
final String departureDate;
final bool oneWay;
final String duration;
final bool nonStop;
final String viewBy;
Default({this.departureDate, this.oneWay,this.duration,this.nonStop,this.viewBy,});
factory Default.fromJson(Map<String, dynamic> parsedJson) {
return Default(
departureDate: parsedJson['departureDate'],
oneWay: parsedJson['oneWay'],
duration: parsedJson['duration'],
nonStop: parsedJson['nonStop'],
viewBy: parsedJson['viewBy'],
);}}
class Meta {
final String currency;
final Links2 links2;
final Default defaults;
Meta(
{this.currency, this.links2, this.defaults});
factory Meta.fromJson(Map<String, dynamic> json) {
return Meta(
currency: json['currency'],
links2: Links2.fromJson(json['links']),
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}');
}
还需要全部解析吗？或者有没有办法只使用数据。
最佳答案
有一个名为:QuickType.io的网站链接:https://app.quicktype.io。
因此，根据您的json，我制作了一个如下所示的模型:
// 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());
