Which platforms are affected?

Web

Description

I added firebase app checker to my main function under await Firebase.initializeApp(options: DefaultFirebaseOptions.currentPlatform);

_setupFirebaseAppCheck() async {
  try {
    await FirebaseAppCheck.instance
        // Your personal reCaptcha public key goes here:
        .activate(
      webProvider: ReCaptchaEnterpriseProvider(
          "my-ReCaptcha-site-key-from-google"),
    );
  } catch (e) {
    print("Error setting up Firebase App Check: $e");
  }
}

When I deploy my app and I inspect the browser console. I'm seeing that App Check is throwing this exception Error setting up Firebase App Check: Unsupported operation: Platform._operatingSystem

I have also registered App Check in the firebase console for web.

What I'm I missing here? Thanks in advance

Reproducing the issue

Setup a flutter web application and add the code above to the main function.

Firebase Core version

3.3.0

Flutter Version

3.22.3

Hello @devroldy, I'm not reproducing this issue on my end, can you provide a complete sample?

Error: Unsupported operation: Platform._operatingSystem I'm getting the same error on Flutter Web when deployed. Please try after deployment because during debugging it works fine.
