I need a seasoned Flutter developer to build the front-end for my mobile app and wire it up to our already-running backend. Scope • Create an intermediate-level interface that goes beyond stock widgets—custom cards, lists, and form elements are expected. • Apply the ready-made theme/template I’ll share, adapting colors, typography, and spacing so the look stays consistent. • Implement user authentication (login, registration, session handling) through the supplied REST endpoints. • Fetch and display data from several API calls, handling loading, empty, and error states gracefully. • Enable push notifications using Firebase Cloud Messaging. What I’ll provide • Full API documentation and Postman collection. • Access credentials for the staging server. • The original design theme files. Acceptance Criteria 1. All screens compile and run on both Android and iOS without warnings. 2. Authentication flow is secure and persists sessions between app launches. 3. Data lists refresh smoothly with pull-to-refresh and paginated loading. 4. Push notifications are received in foreground and background with proper routing. 5. Code is clean, well-commented, and follows Flutter best practices; state management via Provider, Riverpod, or Bloc is fine—choose what you’re comfortable with. If you have solid Flutter experience and can turn API specs into a polished, responsive UI, let’s get started.
