Flutter: Undefined symbols for architecture arm64

Issue

After migrating to null-safety and flutter 2 I get problem with ios build:
I run flutter clean; rm ios/Podfile.lock pubspec.lock; rm -rf ios/Pods ios/Runner.xcworkspace; flutter run --flavor dev -t lib/main_dev.dart

and got this logcat:

    Undefined symbols for architecture arm64:

What I try and it did’t help:

  • pod deintegrate && rm Podfile.lock && pod install --repo-update
  • set up platform :ios, '12.0' in Podfile
  • set up manually architectures in Build Settings as arm64

This problem I have on two flutter projects, but I have no idea how to fix it.

UPD:
It’s look like a problem with OneSignal https://github.com/OneSignal/OneSignal-Flutter-SDK/issues/389

UPD2:
