Generate Flutter IPA file for testing on IOS Physical Device

I have a Flutter project ready and need an IPA file generated for testing on a physical iPhone device. An Apple Developer account is not necessary as I want IPA for testing on the physical device. We can use The Diawi or anything available to distribute the IPA test app. You must have a Macbook, Mac Air, or simply XCode. The app is written in Flutter and it's ready. I have a GitHub repository with the code. Ideal Skills: - Proficient in Flutter - Experienced with iOS app development - Knowledgeable about Apple Developer account setup - Able to generate IPA files Please provide a comprehensive plan on how you intend to handle this project.
