Usage #
A simple usage example:
import 'package:cookie_jar/cookie_jar.dart';

void main() async {
final cookieJar = CookieJar();
List<Cookie> cookies = [Cookie('name', 'wendux'), Cookie('location', 'china')];
// Saving cookies.
await cookieJar.saveFromResponse(Uri.parse('https://pub.dev/'), cookies);
// Obtain cookies.
List<Cookie> results = await cookieJar.loadForRequest(Uri.parse('https://pub.dev/paths'));
print(results);
}

Classes #
SerializableCookie #
This class is a wrapper for Cookie class.
Because the Cookie class doesn't support Json serialization,
for the sake of persistence, we use this class instead of it.
CookieJar #
CookieJar is a cookie container and manager for HTTP requests.
DefaultCookieJar
DefaultCookieJar is a default cookie manager which implements the standard cookie policy declared in RFC.
It saves the cookies in the memory, all cookies will be cleared after the app exited.
To use it:

final cookieJar = CookieJar();

PersistCookieJar #
PersistCookieJar is a cookie manager which implements the standard cookie policy declared in RFC.
PersistCookieJar persists the cookies in files,
so if the application exit, the cookies always exist unless call delete explicitly.
To use it:
// Cookie files will be saved in files in "./cookies/4/"
final cookieJar = PersistCookieJar(
ignoreExpires: true, // Save/load even cookies that have expired.
);

Note: When using the [FileStorage] in Flutter apps,
use path_provider to obtain available directories.

Directory tempDir = await

getTemporaryDirectory();

final tempPath = tempDir.path;
final cookieJar = PersistCookieJar(
ignoreExpires: true,
storage: FileStorage(tempPath),
);

Storage
You can customize your own storage by extending Storage, see FileStorage for more details.
APIs #
Future
Save the cookies for specified uri.
Future<List
Load the cookies for specified uri.
Future
Delete cookies for specified uri.
This API will delete all cookies for the uri.host,
it will ignore the uri.path.
If withDomainSharedCookie is true ,
all domain-shared cookies will be deleted.
Future
Delete all cookies.
Working with HttpClient #
Using CookieJar or PersistCookieJar manages
HttpClient 's request/response cookies is quite easy:
final cookieJar = CookieJar();
request = await httpClient.openUrl(options.method, uri);
request.cookies.addAll(await cj.loadForRequest(uri));
response = await request.close();
await cookieJar.saveFromResponse(uri, response.cookies);

Working with dio #
dio is a powerful HTTP client for Dart/Flutter,
which supports global configuration, interceptors, FormData, request cancellation,
file uploading/downloading, timeout, and custom adapters etc.
dio also supports to manage cookies with cookie_jar
using dio_cookie_manager.
For example:
import 'package:dio/dio.dart';
import 'package:dio_cookie_manager/dio_cookie_manager.dart';
import 'package:cookie_jar/cookie_jar.dart';

void main() async {
final dio = Dio();
final cookieJar = CookieJar();
dio.interceptors.add(CookieManager(cookieJar));
await dio.get('https://pub.dev/');
// Print cookies
print(await cookieJar.loadForRequest(Uri.parse('https://pub.dev/')));
// Another request with the cookie.
await dio.get("https://pub.dev/");
}
