Fyi library only supports biometric passport standard ICAO 9303 aka MRTD. Your ID card has to support this standar in order to read it with this library.

Looking at pointycastle code that you linked it's definitively wrong IV size for block cipher modes. There is already issue for this but no response yet: https://github.com/bcgit/pc-dart/issues/200
