Tajer China
One Flutter codebase, two store reviews. Most of the hard part was outside the code: assets, listings and the review notes for each store.

Tajer China is a trade marketplace. The product lives on a phone, and it had to be on both stores at the same time.
What was built. A mobile app for Google Play and the App Store from one Flutter codebase. Buyers browse listings, search, and get in touch with sellers from inside the app. The app was taken through signing, store listings and review on both platforms, and released.
Stack. Flutter and Dart, one codebase for Android and iOS, released through Google Play Console and App Store Connect.
What was hard. Two stores, two review processes, one release date. The build pipeline produces both binaries from one tag, and the listings, screenshots and privacy declarations were prepared for both stores in parallel so neither review held up the other. Right-to-left screens were checked on physical devices, not only the simulator.
