Cookie Manager

CookieManager Interceptor can help us manage the request/response cookies automatically. CookieManager depends on cookieJar package :

The dio_http_cookie_manager manage API is based on the withdrawn cookie_jar.

You can create a CookieJar or PersistCookieJar to manage cookies automatically, and dio use the CookieJar by default, which saves the cookies in RAM. If you want to persists cookies, you can use the PersistCookieJar class, for example:

dio.interceptors.add(CookieManager(PersistCookieJar()))

PersistCookieJar persists the cookies in files, so if the application exit, the cookies always exist unless call delete explicitly.

Note: In flutter, the path passed to PersistCookieJar must be valid(exists in phones and with write access). you can use path_provider package to get right path.

In flutter:

Directory appDocDir = await getApplicationDocumentsDirectory();
String appDocPath = appDocDir.path;

var cj = PersistCookieJar(ignoreExpires: true, storage: FileStorage(appDocPath +"/.cookies/" ));
dio.interceptors.add(CookieManager(cj));
