Flutter with flavors not building to iOS

Question

Goody day,

When building to android I have no issues with using the flavors.

This is not the case for iOS, I receive the following error:

Finished with error: Exception: Source directory "/Users/[HOME]/[PROJECT]/build/ios/Release-iphonesimulator/Runner.app" does not exist, nothing to copy

Please see flutter doctor -v:

You'll need to configure a custom scheme to define flavors for the iOS build. From the error you've received, it seems that the build is non-existent. Follow this guide to configure the custom scheme for your iOS build's flavor.
