Flutter API Integration (₹7k)

I have a Flutter mobile app with the entire UI already built; it only needs a few cosmetic tweaks. What I really need now is for someone to wire up roughly 15–16 RESTful APIs that deliver product data. Every call is secured with OAuth, and I have clear endpoint documentation ready to share the moment we start.

Here’s what I expect:
• Integrate all endpoints so the app can list, create, update, and delete product information as defined in the docs.
• Apply any minor UI adjustments required to accommodate new states (loading, empty lists, error messages).
• Handle OAuth token retrieval, refresh, and secure storage.
• Return clean, well-commented Dart code pushed to my Git repository along with instructions to reproduce a successful build.
• Run through basic functional testing so I can install the APK/IPA and see each API in action.

The current codebase is organized and uses Provider for state management; feel free to suggest improvements if it speeds things up without adding complexity.

My budget is about ₹7,000, so please keep scope to the essentials described above. If you’re confident working with Flutter, RESTful APIs, and OAuth, let’s talk and get this wrapped up quickly.
