Flutterfire: 🐛 [firebase_auth] sendEmailVerification on iOS sends default link even with actionCodeSettings.

[ibrahimbroachwala]

Bug report

When calling sendEmailVerification() on auth object along with actionCodeSettings, the default verification link is received in mail, but configured link with dynamic link as mentioned in actionCodeSettings should be received. It works in android, but it doesn't in iOS. I am testing in iOS emulator. I guess it shouldn't make a difference with a real device.

Steps to reproduce

Steps to reproduce the behavior:

1. Authenticate user with Firebase auth.
2. Create a actionCodeSettings object with your own dynamic link such as "example.page.link", along with android package name and iOS bundleId.
3. Call user.sendEmailVerification(actionCodeSettings)

 var actionCodeSettings = ActionCodeSettings(
        url: "https://www.example.org/?email=$email",
        dynamicLinkDomain: "example.page.link",
        android: {
          "packageName": "com.example.app",
          "installApp": true,
          "minimumVersion": "10"
        },
        iOS: {"bundleId": "com.example.app"},
        handleCodeInApp: true);
await auth.sendEmailVerification(actionCodeSettings);

The email received in mail starts with: https://example.firebaseapp.com/..... which is incorrect.

Expected behavior

The email received in mail should be configured as per the actionSettings parameters passed.

The desired email link should start with: https://example.page.link?.....

Hi @ibrahimbroachwala
Can you please provide a complete reproducible minimal code sample
Thank you

[bkoznov]

I have the same issue. Using a iPhone XS. Modifying the action link in the template in Firebase Console changes what I receive in my email, but modifying actionCodeSettings doesn't. In fact, many fields of actionCodeSettings doesn't seem to have any impact (url, handleCodeInApp, dynamicLinkDomain). This is a fairly recent regression, it was working properly ~1-2 months ago.

[bkoznov]

This now works for me as of firebase_auth: 0.18.1+2. The patch notes FIX: on iOS use sendEmailVerificationWithActionCodeSettings instead of sendEmailVerificationWithCompletion (#3686 ). Based on this, I think either this issue is a duplicate of #3571 or I commented on the wrong issue. Either way, happy it is fixed!

[ibrahimbroachwala]

I tested in firebase_auth: 0.18.1+2 as @bkoznov mentioned. Its working fine on iOS now 👍🏼

However there is no sendEmailVerificationWithActionCodeSettings() method.

It works with this await user.sendEmailVerification(actionCodeSettings);

Thanks @bkoznov.
Closing this issue.
