[hortigado]

🔖 Feature description

Hello, I don't really know how to make a pull request on Github. But you could add these simple lines so that the createOAuth2Session function returns the cookie in Flutter. The same could be applied for createEmailSession.
Thanks, this is useful when using external packages, for example in my case, or to implement offline first

🎤 Pitch

Please help by keeping this in mind, it is important to support offline packages first.
