问题
When I built my iOS app, it opened perfectly in the simulator on my Macbook. When I publish the app on the itunes store, the app does not work anymore. The splashscreen is shown, but stays on the screen.

Solution for me:
1) updated my iOS toolchain with flutter doctor
2) flutter clean
3) flutter build ios --release in the terminal
4) Archive in Xcode

I tried various solutions. But finally i found out issue was version of my android studio(ide used for development for flutter, in my case). I updated my version to 3.2.1 and then followed instructions to run in xcode and it worked in my case. Hope it helps!

I fix this by remove project_root/ios/Pods/ & project_root/ios/Podfile.lock and run pod install again after flutter clean & flutter build ios --release
