I need a complete multivendor food-delivery ecosystem built with Flutter. Core features must include vendor registration and management, real-time customer order and delivery tracking, payment-gateway integration, and a delivery-partner (driver) module. The system should recognise four distinct roles—Admin, Vendor, Customer and Driver—each with its own dedicated interface. While the mobile apps can be cross-platform in Flutter, I also need a responsive web-based admin panel that lets me onboard vendors, monitor orders, reconcile payments and oversee drivers from one place. Deliverables • Flutter source code for Customer, Vendor and Driver apps • Web admin panel with role-based access and analytics dashboards • Secure, documented API layer connecting mobile clients and admin panel • Integrated payment gateway (Stripe, PayPal or similar) ready for live transactions • Basic documentation covering environment setup, build steps and deployment Acceptance criteria 1. A new vendor can sign up, upload menus and start receiving orders without manual intervention. 2. Customers track each order from confirmation through driver delivery on an interactive map. 3. Admin can suspend a vendor, refund an order or reassign a driver directly from the panel. 4. All money flows reflect in the transaction log and match the payment gateway’s records. Any reusable boilerplate is welcome as long as it is properly licensed. Please keep the code clean, well-commented and ready for future feature additions.
