[firebase-auth][ios]: `linkWithProvider` throws error after tapping on `Done` button

[Albertbol]

Bug report

Describe the bug
Hey,
I came here from a related issue flutter/flutter#102590.
I have updated to the latest versions of firebase auth and core.
And whenever I cancel not native authentication link methods I receive:

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'One of IDToken, accessToken, pendingToken, or requestURI must be supplied.'
*** First throw call stack:

Steps to reproduce

Steps to reproduce the behavior:

Reproduce is straightforward:
Link with the provider as recommended:

FirebaseAuth.instance.currentUser?.linkWithProvider(provider here like GoogleAuthProvider(), GithubAuthProvider(), MicrosoftAuthProvider())

Click "Done" and get crash + error.
This happens both with firebase auth emulators and internally released, only on physical device iPhone 13 16.0 ios. I think it's related to safari acting weirdly as there is no cancel button but only "Done" maybe it leads to submissions instead of canceling and leads to an unexpected error.

Thanks for the report @Albertbol
I tried using linkWithProvider(GoogleAuthProvider()) in plugin example and used iPhone 6s (OS 15.6.1), but was unable to replicate this. With GoogleAuthProvider() enabled, after login, I see below screen after entering details, I didn't see done button.

Can you provide screenshot wherein you see done button which leads to the crash ?

Also, is there a way for you to check also on lesser iOS version device ( < 16) to see if it replicate on it too ?

[Albertbol]

Hey @darshankawar
I tried an emulator also: iPhone 13 mini iOS 15.5 (it's the same in the internal release)
linkWithProvider(GootleAuthProvider())

So this action "Done" is crashing.

[darshankawar]

Thanks for the details. I am able to replicate this using below code sample and then running it on iOS device. Tapping on done button throws below error log.

return MaterialApp(
      title: 'Firebase Example App',
      theme: ThemeData(primarySwatch: Colors.amber),
      home: Scaffold(
        body: ElevatedButton(
          child: Text('Login'),
          onPressed: () {
            FirebaseAuth.instance.currentUser?.linkWithProvider(GoogleAuthProvider());
          },
        )
      ),
    );
