Flutter IOS 尝试在试飞时构建存档不起作用

Question

I am developing a flutter project. While I run my application on an IOS device it's working perfectly. I want to release my application in test flight for testing, when I tried to archive (Product->Archive) am got the below error.

Undefined symbols for architecture armv7:
  "_kServiceInfoFileType", referenced from:
      -[FIRDynamicLinks configureDynamicLinks:] in FIRDynamicLinks.o

I am using Xcode version 12.5.

Answer 1

you highlight a warning.... warnings should not be the problem.

try this.

1. in flutter project dir -> flutter clean
2. in ios dir -> delete Podfile.lock
3. run -> pod repo update
4. check in xcode your app account settings (provisioning files, certificates etc.)

Answer 2

your third party lib not support armv7 arc

try this:

1. in ios dir, open runner.xcworkspace
2. project-> runner build settings find Architectures, set the value to arm64
3. targets-> runner build settings find Architectures, set the value to arm64
4. run pod install

this works for me, but this option will only support the devices release after iPhone 5s, and can not support old device

Answer 3

You got Undefined symbols for architecture armv7 , which might be because you don't have armv7 in your Architecture defined. Try this:
