如何在flutter上使用cookie发出http请求？

http: ^0.13.4

import 'package:http/http.dart' as http;

Future<String> fetchDataWithCookie() async {
  var url = Uri.parse('https://example.com/api/data');
  var cookie = 'your_cookie_value';

  var response = await http.get(url, headers: {'Cookie': cookie});

  if (response.statusCode == 200) {
    return response.body;
  } else {
    throw Exception('Failed to fetch data');
  }
}

fetchDataWithCookie().then((data) {
  print(data);
}).catchError((error) {
  print(error);
});
