Flutter Consultation Booking App

I need a Flutter developer to build a polished mobile application that lets users browse available time slots and book consultation appointments from their phones. The app must run smoothly on both iOS and Android and communicate with my existing REST-based backend for everything—user authentication, schedule retrieval, booking creation, rescheduling, and cancellations.

Here’s what matters most:
• Clean, maintainable Flutter code that compiles for iOS and Android without platform-specific hacks.
• Solid REST API integration with proper error handling and token-based security.
• A straightforward flow where a user logs in, views consultant availability, confirms a slot, and receives an in-app and push notification of the booking.
• Responsive, modern UI that feels at home on both platforms and follows Material design guidelines.
• A short hand-off document and a Git repo so I can continue development internally.

Acceptance is simple: if I can install the app on recent iOS and Android devices, complete the booking flow end-to-end, and see the correct data reflected through the API, the project is done. Let’s keep communication clear and iterate quickly—I’m ready to provide the endpoint specs and test credentials as soon as we start.
