Building a new mobile app in Flutter and I need a developer who already has three to four solid years working with the framework and, in particular, with the BLoC state-management pattern. The project targets both iOS and Android from a single codebase, so your experience shipping apps to the App Store and Google Play will matter. You will take charge of the full Flutter layer: setting up the architecture with clean, well-documented BLoCs, wiring up screens, and ensuring smooth performance on each platform. A clean folder structure, readable Dart code, and clear separation of concerns are non-negotiable, as this codebase will grow over time. Typical day-to-day work will include: • Converting Figma (or comparable) designs into responsive Flutter widgets • Implementing new features behind maintainable BLoCs and Cubits • Integrating with existing REST / GraphQL endpoints and handling offline states gracefully • Writing unit and widget tests for critical flows • Preparing both iOS and Android builds for QA and store submission Acceptance criteria: 1. All user flows compile and run without errors on the latest stable Flutter channel for both iOS and Android. 2. Core functionality is covered by meaningful unit and widget tests (minimum 80 % coverage on the feature modules you touch). 3. State is managed exclusively through flutter_bloc with clear, documented events and states. 4. CI build passes on first merge request. If this matches your background and you can start soon, let’s talk about timelines and milestones.
