Description
There were a couple of similar issues: #17216, #16845.
The former one was closed because the author and the flutterfire team members couldn't reproduce the issue, therefore couldn't fix it.
2026-04-03.13.12.37.mov
Reproducing the issue
- Launch the example app
- Double tap the "Sign in with Apple" button. If you're launching on simulator then call the method
_handleMultiFactorException(_signInWithApple)twice on button tap, because you won't be able probably to click the button twice that fast as it needs to reproduce the issue. On physical device i am able constantly to tap twice fast enough to get the error on the video and crash the app.
