I just upgraded Flutter and Xcode and now my successful built are failing when I am uploading it to the App Store connect. The error is:
ERROR ITMS-90208: "Invalid Bundle. The bundle Runner.app/Frameworks/App.framework does not support the minimum OS Version specified in the Info.plist."

Before the upgrade, it was working fine. I checked the Minimum OS versions in Xcode and both are set to iOS 13.0 (i.e info.plist, iOS Deployment Target).

Is there a bug in one of the upgraded tool (Flutter or Xcode)?
