Answer 1

Yes, the error message suggests that the Info.plist file does not contain a valid CFBundleVersion.

You can try to fix this issue by setting a valid CFBundleVersion value in your Info.plist file. The CFBundleVersion value should be a string that represents the version of your application.

You can set a valid CFBundleVersion value by updating the $(FLUTTER_BUILD_NUMBER) placeholder in your Info.plist file to a valid version number. For example, you can replace $(FLUTTER_BUILD_NUMBER) with 1.0.0 or any other version number that follows the format x.y.z.

After setting a valid CFBundleVersion value, you can rebuild and try running your application again.
