@lunching-patryk-konieczny Thank you for all informations. Have you checked if you have the same error in our example?

[lunching-patryk-konieczny]

Yes, I have checked and the example app was working fine. The only difference I found was with swift_version in Xcode settings. Setting it to version 5 fixed the problem with p24 lib, but to do that I have to recreate iOS platform in flutter project, (but that was some problem with old version of flutter that we first used when starting our project 3 years ago).
