I need to push a fresh build of my existing Flutter app to both the App Store and Google Play, but two blocking bugs stand in the way. First, the login flow behaves unpredictably—users either can’t sign in or are bounced back to the splash screen. Second, several navigation links route to the wrong pages. There are no crashes or performance slowdowns, just this incorrect functionality that prevents a smooth user experience. Your job is to dig into the Flutter codebase, find the root cause of these login and navigation issues, patch them, test thoroughly, and then create release-ready builds for iOS and Android. Once the fixes are confirmed, you’ll handle the entire submission process, including certificates, keystores, and any review feedback, until the update is live in both stores. Deliverables • Clean, well-commented code with both bugs resolved • Signed release builds (IPA and AAB) ready for distribution • Successful publication in App Store Connect and Google Play Console • Brief change log outlining what was modified Acceptance Criteria • Users can log in consistently on iOS and Android • All navigation routes land on the correct screens without unexpected redirects • Both stores approve the update with no further issues If you have recent experience debugging Flutter projects and managing store submissions, let’s get this update out to users quickly.
