How do I save session cookie from response in flutter?

Question

Let's say I log into an api with my flutter app. In an website, they automatically store the login cookie and then can use it. But in flutter app, how do I store the cookies and session? And how do I pass that into post to let the api know I have a valid login session?

1) The "standard" way to access cookies is to embed some Javascript in your HTML. Perhaps this is an option for you. 2) For Flutter, you have (at least) two challenges: a) programmatically reading the cookie, and b) persisting it to local storage.

Q: It's making me more confused, I just want the part to extract cookie and how to use it.

There are a number of complexities, depending on exactly what you ultimately want to do.

But let's assume:

Your Flutter app makes an HTTP request (GET, PUT, etc.)
The server (e.g. your Flask app) returns cookies in the HTTP response (in the HTTP response header).

Let's further assume your HTTP code looks something like this:

Future<http.Response> fetchAlbum() {
  return http.get(Uri.parse('https://jsonplaceholder.typicode.com/albums/1'));
}

In that case, you should be able to reference the cookies property of the Response object returned from the server.
