Android crash

[LucaIaconelli]

Greetings,

I am experiencing a crash on Android when I try to make the authorizeAndExchangeCode call.

flutter_appauth: ^4.2.1
Flutter 3.3.8

Could you help me identify the problem?

Thanks in advance

Maybe your idToken is null.

You would need to debug this further yourself but as mentioned by @lsaudon, looks like it could from how the id token is null
