iOS Crash when opening a deep link after completing an OAuth flow
Steps
- Complete normal SSO OAuth flow with Google
- Background the app and leave it running
- Open a deep link that would open the app.
Seems like FlutterAppauthPlugin may be resending something related to the oauth redirect

Looks like this only happens if the deep link has the same URI structure as the SSO Oauth redirect.
I saw this when trying to see if i could use the url_launcher plugin to see if that could be used for logout. Unfortunately, I don't know of a solution at the moment so any assistance would be much appreciated
