Flutter Appointment Booking App Build

I’m ready to move from concept to code for a full-featured appointment booking application built entirely with Flutter. The app will serve three distinct roles—Admin, Service Provider, and Customer—each with tailored dashboards and permissions.

Core functionality I need:
• Seamless calendar integration so providers can set availability and customers can see real-time slots
• Secure payment processing at checkout (Stripe or a comparable gateway)
• Push and email notifications for new bookings, changes, and reminders

I’ll share a detailed reference app and brand guidelines once we agree to collaborate, and I’m happy to refine the scope together before sprint planning. Your deliverable will be a production-ready Flutter project (iOS, Android, and web if feasible) with clean, well-documented code and instructions for deployment to Firebase or a similar backend.

If your team or you have shipped similar booking or scheduling apps, I’d love to see a link, a quick rundown of the tech stack you used, and how you handled calendar sync and payments.
