Publish Existing Flutter iOS App

I have a fully functional Flutter iOS codebase that is ready for release. The signing certificates, provisioning profiles, and Apple Developer settings are already in place, and the icons plus screenshots have been prepared. Your task is simply to turn this code into a live listing on my Apple App Store account.

The workflow I expect: compile and archive the production build in Xcode, upload through App Store Connect, run it through TestFlight, address any validation messages Apple returns, and finally release the build to the public store. I will supply account access and two-factor codes immediately, so the process should be quick.

Acceptance criteria
• The app passes review and appears publicly in the App Store under my account.
• Only the supplied source, assets, and metadata are used.
• Each submission step (build number, certificates, upload commands, review notes) is documented for my records.
