I have this design, I created it and put the data manually, the question is how can I get the data in the image and it is from this website (https://jsonplaceholder.typicode.com/posts) and display it in the same design
CodePudding user response:
var url = Uri.parse("https://jsonplaceholder.typicode.com/posts");
var response = await http.get(url);
if (response.statusCode == 200) {
var responseJson = jsonDecode(response.body);
responseJson as List;
return responseJson.map((e) => YourModel.fromJson(e)).toList();
}
CodePudding user response:
Firstly, you can paste your JSON in the link below, click convert and get your Dart classes for free.
Secondly, you can copy the result which is named JsonPlaceHolderResponse
and create a new file in your project, and paste the result there.
Finally, you can use this code to get your data from defined API:
import 'package:http/http.dart';
Future<JsonPlaceHolderResponse?> getData(String url) async {
final _response = await Client().get(
url
);
if (_response.successResponse) {
final _json = jsonDecode(_response.body);
return JsonPlaceHolderResponse.fromJson(_json);
} else {
return null;
}
return null;
}
extension ResponseExtension on Response {
bool get hasWrongCredentials => statusCode == 422;
bool get tooManyRequests => statusCode == 429;
bool get successResponse => statusCode >= 200 && statusCode < 300;
}
