Flutter: Undefined symbols for architecture arm64

Question

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 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:

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

Answer 1

I found solution for this problem:

1. Set up selected configurations as None

2. Check that check box is turn on

More info here and here

Answer 2

I also faced this problem and fixed with

Build setting -> search Valid Architecture:

Remove armv7 from the list

If Xcode version > 12.0 Then go project or target -> Build Settings -> Excluded Architecture

Then Add armv7
