Setup iOS Flavors in Flutter

I need assistance in setting up iOS flavors in my Flutter project to match the existing Android flavors. The Android project currently has Development, Staging, and Production flavors, primarily used for testing different environments. I require the same setup for iOS, with an additional need for different app names for each flavor.

Key Requirements:
- Configure iOS flavors to mirror Android's Development, Staging, and Production setups
- Ensure each iOS flavor has a distinct app name
- Maintain consistency in environment testing across both platforms

Ideal Skills and Experience:
- Proficiency in Flutter development with experience in setting up flavors for both Android and iOS
- Strong understanding of iOS build configurations and Xcode
- Ability to manage app naming conventions and ensure seamless integration across platforms

Your expertise will help streamline the development process and ensure consistent testing environments across Android and iOS.
