Description

When I tried to run a Flutter sample on iOS, I got the following error in Xcode:

Auth0/NSURL+Auth0.swift:9: Fatal error: Unexpectedly found nil while unwrapping an Optional value

I have already set up the Allowed Callback URLs and Apple Team ID in the Auth0 Settings. I have also added my associated domain in Xcode. Do you know what I should do to resolve this?

Reproduction

1. Download the Flutter sample
2. Change to the bundle ID obtained from Apple Developer and register it in Allowed Callback URLs, etc.
3. Prepare the .env file
4. Register the associated domain
5. Execute flutter run

Additional context

The Okta sample login is successful, and 'It Works!' is displayed.

Platform

iOS

Platform version(s)

Flutter 3.19.6/iOS 18.0

Sorry, the format of my domain was incorrect. It's fixed now, so I'll close this🙇🏻‍♀️
