Fetch data with http.get.
What is http.get?
http.get is a method used to fetch data from a URL. It takes a Uri and returns a Response.
final response = await http.get(
Uri.parse('https://api.example.com/data'),
);
print(response.body);Response carries the returned data and the statusCode.
Uri.parse and Response
You convert the URL string to a Uri object with Uri.parse. The Response object carries the returned data and the status code.
final uri = Uri.parse('https://api.example.com/data');
final response = await http.get(uri);
print(response.body);response.body gives the returned content as a string.
Practice Fetch data with http.get
Write an async method veriCek. Fetch data with http.get(Uri.parse('https://api.example.com/veri')) and print response.body with print('gövde: ${response.body}'). In main, await veriCek and call print('istek tamam').
Starter code
import 'package:http/http.dart' as http;
// veriCek: async metot ekle
void main() async {
// veriCek'i çağır ve mesaj yazdır
}Sample solution
import 'package:http/http.dart' as http;
Future<void> veriCek() async {
final response = await http.get(Uri.parse('https://api.example.com/veri'));
print('gövde: ${response.body}');
}
void main() async {
await veriCek();
print('istek tamam');
}Expected output
gövde: {"isim":"Ayşe"}
istek tamam
