Pop up for entering credentials for apple login disappears immediately in flutter web

[flutterwithfaiz]

Sign in with apple is working in debug mode but when I deploy my flutter web app on firebase and tried to get logged in using apple credentials, pop up immediately disappeared when I clicked Login button.

@flutterwithfaiz do you see any errors in the network tab or console?

Can you please tell me what did you do to make it in your side @flutterwithfaiz ?
I m getting an UNKOWN_SIWA_ERROR when trying the web version.

Hey I'm getting the same issue when debugging.
When I host on firebase I get: "Uncaught Unsupported operation: Platform._operatingSystem"
Did you find a solution to your issue?
I have gone over the set up process a few times now and I'm pretty confident I followed each steps for setting up web configuration.

Got the same issue as well. On local the popup comes up fine but once deployed no popup at all and the error in console is:

This is how I am setting the redirect Uri:

Uri get appleRedirectURI {
    if (kIsWeb) {
      //return Uri.parse('https://${window.location.host}/');
      return Uri.parse(appEnvironment.baseURL);
    } else {
      //For android
      return Uri.parse('https://foobar.com/callbacks/sign_in_with_apple');
    }
  }
