Flutter android - notification working in ios testflight does not work when downloaded from app store

I published the "B&B Prosthetic Hair" application that I wrote with Flutter to the app store and google play, androşd receives notifications completely without any problems, it works in testflight and emulator on ios, but when you download it from the app store, the notification does not appear, and there is no notification permission in the settings. But testfliht also shows up.
