The Flutter UI for my app is already in place, but it still needs a professional touch before release. I want the current screens fine-tuned—think small layout adjustments, a few fresh widgets, and some tweaks to the existing components—followed by a solid REST API layer that brings every screen to life. Here’s what I expect: • Diagnose and fix any compile-time or run-time issues so the project builds cleanly on both Android and iOS. • Refactor or polish the layouts where spacing or alignment feels off, add the missing UI elements, and adjust existing ones so the experience is consistent across devices. • Connect each screen to my REST endpoints, handle responses gracefully, and surface errors to the user where appropriate. • Leave the code organized, well commented, and ready for me to maintain (clean architecture, proper state management, etc.). • Supply a working build plus source so I can run flutter run and see everything working end-to-end. If you’re confident in Flutter, Dart, and REST-based integrations, I’m ready to share the repo and API docs so we can get this wrapped up quickly.
