after you get the data pass it to this function
final yourModel = yourModelFromMap(jsonString);
it will parse json to this object
and you can use it like
yourModel.data.<any value you want>
.
import 'dart:convert';
YourModel yourModelFromMap(String str) => YourModel.fromMap(json.decode(str));
String yourModelToMap(YourModel data) => json.encode(data.toMap());
class YourModel {
YourModel({
required this.data,
required this.status,
});
Data data;
bool status;
factory YourModel.fromMap(Map<String, dynamic> json) => YourModel(
data: Data.fromMap(json["data"]),
status: json["status"],
);
Map<String, dynamic> toMap() => {
"data": data.toMap(),
"status": status,
};
}
