The task is to build a production-ready mobile application with Flutter that ships seamlessly to both iOS and Android from a single code-base. I will provide the product concept, brand assets, and any required APIs; your role is to turn those inputs into clean, maintainable Dart code, integrate the UI with the back-end services, and prepare release builds for the App Store and Google Play. Key success criteria: • A smooth, native-feeling experience on current iOS and Android devices. • Source code managed in Git with clear commit history and documentation. • Build artifacts ready for TestFlight and internal testing on Android, followed by store-ready release builds. Please plan to collaborate on state management choices, automated testing, and deployment workflow so we can keep the project scalable beyond its first launch.
