I have an in-progress point-of-sale application written in Flutter and targeted for iOS. The core codebase is already in place, but it still needs polish and a steady hand to reach App Store–ready quality. Your mission: • Audit the existing Flutter project, document what’s working and what still needs attention. • Close the remaining feature gaps so day-to-day sales, receipt printing, and product searches run smoothly. • Integrate or tidy up any third-party services already wired in (payment gateway, inventory, CRM) and flag additional integrations that could streamline the workflow. • Fix outstanding bugs, boost performance, and ensure rock-solid offline handling with graceful sync once connectivity returns. • Produce a signed, distributable build ready for TestFlight and final App Store submission, including all required Apple compliance steps. Let me know: • A brief outline of how you would approach the code review and delivery timeline. • Examples of previous Flutter or POS work, especially anything live on iOS. • Any specific questions about the existing architecture before you dive in. Looking forward to getting this system across the finish line together.
