Flutter POS App Publishing

My point-of-sale mobile app is already built in Flutter and fully tested; all core features are locked in and the code is production-ready. What I now need is a specialist who can take the finished build, package it correctly for both Android (Google Play) and iOS (App Store), and guide it through the complete submission and approval process.

Where we stand
• Source code and assets are final.
• The app compiles cleanly for both targets.
• I hold an active Apple App Store developer account, but I have not yet opened a Google Play developer account.

What I’m looking for
You will produce release-grade builds, configure signing certificates, create store listings, compose the required privacy declarations, upload the binaries, and respond to any review feedback until each store shows the app as “Approved” and publicly available.

Key deliverables
1. Published iOS version with live App Store link.
2. Published Android version with live Google Play link (or full guidance on creating the Play developer account if you cannot publish under your own).
3. Final IPA and AAB/APK release bundles plus all store assets returned to me.

Flutter, Xcode, Android Studio, Firebase Crashlytics (already integrated), and standard store-compliance tooling should feel second nature to you.

Once both stores list the app successfully, the project is complete.
