Answer 1

you can use this project https://javiercbk.github.io/json_to_dart/ or this one https://app.quicktype.io/ and select Dart language to help you create models based on json data

Answer 2

You can automatically parse JSON to Dart classes by using this
class Weather {
Request request;
Location location;
Current current;
Weather({this.request, this.location, this.current});
Weather.fromJson(Map<String, dynamic> json) {
request =
json['request'] != null ? new Request.fromJson(json['request']) : null;
location = json['location'] != null
? new Location.fromJson(json['location'])
: null;
current =
json['current'] != null ? new Current.fromJson(json['current']) : null;
}
Map<String, dynamic> toJson() {
final Map<String, dynamic> data = new Map<String, dynamic>();
if (this.request != null) {
data['request'] = this.request.toJson();
}
if (this.location != null) {
data['location'] = this.location.toJson();
}
if (this.current != null) {
data['current'] = this.current.toJson();
}
return data;
}
}
class Request {
String type;
String query;
String language;
String unit;
Request({this.type, this.query, this.language, this.unit});
Request.fromJson(Map<String, dynamic> json) {
type = json['type'];
query = json['query'];
language = json['language'];
unit = json['unit'];
}
Map<String, dynamic> toJson() {
final Map<String, dynamic> data = new Map<String, dynamic>();
data['type'] = this.type;
data['query'] = this.query;
data['language'] = this.language;
data['unit'] = this.unit;
return data;
}
}
class Location {
String name;
String country;
String region;
String lat;
String lon;
String timezoneId;
String localtime;
int localtimeEpoch;
String utcOffset;
Location(
{this.name,
this.country,
this.region,
this.lat,
this.lon,
this.timezoneId,
this.localtime,
this.localtimeEpoch,
this.utcOffset});
Location.fromJson(Map<String, dynamic> json) {
name = json['name'];
country = json['country'];
region = json['region'];
lat = json['lat'];
lon = json['lon'];
timezoneId = json['timezone_id'];
localtime = json['localtime'];
localtimeEpoch = json['localtime_epoch'];
utcOffset = json['utc_offset'];
}
Map<String, dynamic> toJson() {
final Map<String, dynamic> data = new Map<String, dynamic>();
data['name'] = this.name;
data['country'] = this.country;
data['region'] = this.region;
data['lat'] = this.lat;
data['lon'] = this.lon;
data['timezone_id'] = this.timezoneId;
data['localtime'] = this.localtime;
data['localtime_epoch'] = this.localtimeEpoch;
data['utc_offset'] = this.utcOffset;
return data;
}
}
class Current {
String observationTime;
int temperature;
int weatherCode;
List<String> weatherIcons;
List<String> weatherDescriptions;
int windSpeed;
int windDegree;
String windDir;
int pressure;
double precip;
int humidity;
int cloudcover;
int feelslike;
int uvIndex;
int visibility;
String isDay;
Current(
{this.observationTime,
this.temperature,
this.weatherCode,
this.weatherIcons,
this.weatherDescriptions,
this.windSpeed,
this.windDegree,
this.windDir,
this.pressure,
this.precip,
this.humidity,
this.cloudcover,
this.feelslike,
this.uvIndex,
this.visibility,
this.isDay});
Current.fromJson(Map<String, dynamic> json) {
observationTime = json['observation_time'];
temperature = json['temperature'];
weatherCode = json['weather_code'];
weatherIcons = json['weather_icons'].cast<String>();
weatherDescriptions = json['weather_descriptions'].cast<String>();
windSpeed = json['wind_speed'];
windDegree = json['wind_degree'];
windDir = json['wind_dir'];
pressure = json['pressure'];
precip = json['precip'];
humidity = json['humidity'];
cloudcover = json['cloudcover'];
feelslike = json['feelslike'];
uvIndex = json['uv_index'];
visibility = json['visibility'];
isDay = json['is_day'];
}
Map<String, dynamic> toJson() {
final Map<String, dynamic> data = new Map<String, dynamic>();
data['observation_time'] = this.observationTime;
data['temperature'] = this.temperature;
data['weather_code'] = this.weatherCode;
data['weather_icons'] = this.weatherIcons;
data['weather_descriptions'] = this.weatherDescriptions;
data['wind_speed'] = this.windSpeed;
data['wind_degree'] = this.windDegree;
data['wind_dir'] = this.windDir;
data['pressure'] = this.pressure;
data['precip'] = this.precip;
data['humidity'] = this.humidity;
data['cloudcover'] = this.cloudcover;
data['feelslike'] = this.feelslike;
data['uv_index'] = this.uvIndex;
data['visibility'] = this.visibility;
data['is_day'] = this.isDay;
return data;
}
}
convert json to dart by Weather.fromJson(json);
