I'm trying to figure out how I can decode the following JSON in Flutter.
https://covid.ourworldindata.org/data/owid-covid-data.json
I tried the following structure, but it doesn't work.
@JsonSerializable()
class StatisticsResponse {
Map<String, Country> data;
//List<Country> data;
StatisticsResponse({this.data});
factory StatisticsResponse.fromJson(Map<String, dynamic> json) =>
_$StatisticsResponseFromJson(json);
}
@JsonSerializable()
class Country {
String continent;
String location;
int population;
//Map<String, Data> data;
List<Data> data;
Country({this.continent, this.location, this.population, this.data
});
factory Country.fromJson(Map<String, dynamic> json) =>
_$CountryFromJson(json);
}
Use Map to convert dynamic
to String
. Directly assigning List to List will throw an error. You have create getters yourself.
Consider this example:
(jsonDecode(response.body)["data"] as List).map((e) => e as Map<String, dynamic>)?.toList();
Now assign to an instance of the custom class you have made.
