I’m putting the finishing touches on an event and entrepreneur-booking app built with Flutter. The codebase is stable, yet a few last items stand between us and a public release. What I need you to handle • Upgrade the project to the latest stable Flutter and Dart SDKs without breaking existing functionality. • Restore and extend Stripe: payments worked previously, but a recent refactor broke them. I also want a couple of small add-ons (e.g., clearer error messaging and a lightweight receipt screen). • Knock out a short list of bug fixes and very small feature additions already documented in GitHub issues. • Thoroughly test on both iOS and Android devices/emulators to confirm nothing regresses after the upgrade. • Package, sign and release the production builds to Apple’s App Store and Google Play, guiding the apps all the way through review. Deployment resources (certificates, API keys, store listings and screenshots) are ready on my side, so you can focus on the technical work. When you reply, attach a detailed project proposal outlining the sequence you would follow—upgrade, payment repair, QA, then store submission—and any tools you rely on (Fastlane, Codemagic, etc.). A concise timeline and milestone breakdown will make it easy for me to green-light your plan. I’m ready to start as soon as I see a solid approach.
