Make REST requests with the http package.
What is the http package?
The http package is the official package used to make REST API requests in Flutter. With methods like get, post, put, delete you communicate with a server.
import 'package:http/http.dart' as http;
final response = await http.get(Uri.parse(url));All requests work asynchronously.
REST and http methods
REST is an architecture that works over the HTTP protocol. GET reads data, POST sends new data, PUT updates, DELETE deletes. The http package supports these methods directly.
await http.get(uri); // read
await http.post(uri); // send
await http.delete(uri); // deleteEach method returns a Response.
