How to Fix Domain/Default Pair Error on Flutter

In this Flutter tutorial, you'll learn how to fix the Domain/Default pair error on Flutter

Getting your iOS Flutter builds to work again.

If you’re like me, you’ve been enjoying using Flutter to make some really great apps lately. One of the things about using such a cutting edge framework is that you’re bound to encounter some potentially weird issues…without knowing exactly how to fix it.

I just spent 4 hours on the domain/default pair issue. In your build log it looks like this:

/Users/user/Documents/strutsin/build/ios/Release-iphoneos/Runner.app/Frameworks/App.framework/App: signed bundle with Mach-O universal (arm64) [io.flutter.flutter.app]
    /Users/user/Documents/strutsin/build/ios/Release-iphoneos/Runner.app/Frameworks/Flutter.framework/Flutter: signed bundle with Mach-O universal (armv7 x86_64 arm64) [io.flutter.flutter]
