Where do you see this error? I don't get this.

import 'dart:convert';

class CountryList {
final List photos;

CountryList({
this.photos,
});

factory CountryList.fromJson(List parsedJson) {

List<CountryResponse> photos = new List<CountryResponse>();
photos = parsedJson.map((i)=>CountryResponse.fromJson(i)).toList();

return new CountryList(
    photos: photos
);

}
}

class CountryResponse {
int countryId;
String countryName;

CountryResponse({
this.countryId,
this.countryName,
});

factory CountryResponse.fromJson(Map<String, dynamic> json) => CountryResponse(
countryId: json["CountryId"],
countryName: json["CountryName"],
);

Map<String, dynamic> toJson() => {
"CountryId": countryId,
"CountryName": countryName,
};
}

`Future<List> getCountry() async {
print("hey");
String finalUrl = postsURL+'Country/GetCountry?key=$key';
final response = await http.get(finalUrl);
if(response.statusCode == 200) {
var data = json.decode(response.body);
print(data.toString());
var rest = data as List;
return CountryList.fromJson(rest).photos;
}
}
