I’m enhancing an existing Flutter application and need four separate APIs wired in so the app can automatically keep product data in sync with our back-end services. The endpoints are ready and return JSON; what I don’t have yet is the clean, production-ready Dart code that calls them, parses the responses, and pushes updates through the current provider/bloc structure of the app. The scope is focused on data synchronization—no payment or social media hooks—just reliable, efficient transfer of product details (IDs, images, prices, stock counts, etc.) in both directions. You’ll ensure proper error handling, token-based auth where required, and graceful handling of offline scenarios so the cache updates once connectivity is restored. Deliverables • Integration of all four APIs with clear, well-commented Dart services • Seamless linkage to the existing state-management layer so product lists update instantly in the UI • Simple test cases confirming successful GET, POST, PUT and error responses • A short README outlining setup steps and any config keys required If you’ve already connected REST or GraphQL endpoints in Flutter and can turn around clean, maintainable code quickly, you’ll be a perfect fit.
