iOS Build & Login UI Review with image upload that's working

I have a fully functional Android Flutter codebase that compiles into an APK. I now need an equivalent build for iOS and a quick polish of the existing login screen,product Price not showing in Razorpay Pay payment Gateway and image upload before we push the final release.

Here’s what I’m looking for:

• Produce a working Flutter Program based iOS build (IPA) from the existing project so it runs smoothly on current iPhones and passes App Store validation.
• Review the login module—code is complete, but I’d like minor user-interface improvements (cleaner layout, consistent fonts, and any easy wins that enhance first-time user experience).
• Keep all existing logic intact; with image upload by camera from backend only.
• Share brief implementation notes and the final Xcode project so I can rebuild in the future.

The focus is limited: convert, refine the login UI, and hand over a compile-ready package.
