Hi everyone. Can somebody help me out on how to use SuperTokens with Flutter FE. Documentation says to call FE APIs directly for the thirdparty login flow, but I'm not quite sure how this suppose to work. Specifically I'm trying to implement thirdparty login with Twitch. For that I've added custom twitch provider in SuperTokens config to my Go backend. I see that frontend APIs have

signinup

and

authorisationurl

. My assumption is that I have to call

authorisationurl

API first to get the redirect to the thirdparty provider and then call

signinup

once I get authorisation code from provider. Is that the correct flow? Also the url returned by

authorisationurl

does not include either

redirect_uri

or

state

parameters. Are these supposed to be added my me on the FE manually? Does Supertokens provide any mechanism of handling

state

and / or

nonce

verification ? Thanks.

hey @nicktgn you will have to get twitch's access or id token on the frontend first. This will require you to use any ouaht client lib available for flutter (you can google this). Once you have this, you can send the token to the backend using the signinup API and then your custom implementation for twitch on the backend will kick in

I see. Thanks for reply. I was kinda under impression that ST can handle some of that for me.

yeaaa.. for mobile social login flows, we don't help with the client side oauth as of yet. A primary reason is also cause many providers have very different mobile flows. For examlpe sign in with apple asks the OS to auth the user. Sign in with google requires use of the google's frontend sdk on mobile etc.

Makes sense. And thanks for the link. I'll look into it.
