🐛 [FLUTTERFIRE_UI] email verification spinning circle keeps spinning forever

[graemep-nz]

Bug report

When you click "verify email" an email gets sent and can be clicked on but the spinning circle keeps on spinning and there's no indication that the email verification worked. If you sign out and sign back in, the profile page then shows that the email address has been verified -the verify email button is no longer there. This is on a samsung tab A8 running android 11.

Steps to reproduce

Register with a new email address, go to the profile page and click "verify email".

Expected behavior

The screen should show "email verified" and the spinning circle should disappear.

I've found where the code gets stuck - this call is not returning - what is it doing? final linkData = await FirebaseDynamicLinks.instance.onLink.first;

The code below prints "pending" but never prints "stuck dynamic" (pasting code isn't working properly so I had to paste an image)

[graemep-nz]

For this code, onlinkxx onlink2 and onlink3 all get printed but "first" and "first2" never appear.

  @override
  Stream<PendingDynamicLinkData> get onLink {
    print("onlinkxx");
    var stgp1 =  _onLinkController.stream;
    print("onlink2");
    Future.delayed(Duration(milliseconds: 1000), () {
      print('onlink3');
    });
    return stgp1;
  }


  Future<T> get first {
    print("first");
    Future.delayed(Duration(milliseconds: 1000), () {
      print('first2');
    });
    _Future<T> future = new _Future<T>();
    StreamSubscription<T> subscription =
        this.listen(null, onError: future._completeError, onDone: () {
      print("on Done");
      try {
        throw IterableElementError.noElement();
      } catch (e, s) {
        _completeWithErrorCallback(future, e, s);
      }
    }, cancelOnError: true);
    subscription.onData((T value) {
      print("subscribing");
      _cancelAndValue(subscription, future, value);
    });
    return future;
  }

[graemep-nz]

and if I set a breakpoint and single step into the call to "first" it doesn't go to the first function instead it goes to the exit point of the code below and then a whole bunch of other places and never returns from the call to "first" -

  Future<void> sendEmailVerification([
    ActionCodeSettings? actionCodeSettings,
  ]) async {
    await _delegate.sendEmailVerification(actionCodeSettings);
  }
