I get the "Refused to set unsafe header "cookie"" error when I try from flutter web

Hi!

When I am using Flutter built on chrome and try to send a post request to my Express server to sign in, the cookie is not stored and the console reads the error : Refused to set unsafe header "cookie".

Here is the code that calls from the server side:

final response = await Requests.post("http://localhost:3000/signin",
json: {"username": username, "password": password},
withCredentials: true);

response.raiseForStatus();
