I have the requirement to obtain a unique permanent identifier which allows me to identify an iOS device (iPhone) using a Flutter application.

I've understood that the IMEI is impossible to be used because Apple doesn't allow to retrieve it directly by code (post), I've thought about using the MAC address but how can I retrieve it by code?

I've read about the identifierForVendor but it changes if the app is uninstalled and then reinstalled so it is not permanent (and I cannot use it in my use case).

Finally I've decided to use the "identifierForVendor" because it seems the more appropriate for the app context.
