I’m setting up a hyper-local service, Apna City Delivery, that will operate only in Madhepura, and I need a straightforward Android app built with Flutter. The entire interface, including any system messages, must appear in Hindi—no bilingual toggle required. Core user flow • OTP-based mobile login • Category browsing (Kirana, Sabzi, Milk/Bread, Medicine) with product names and prices • Address management and cash-on-delivery checkout • Real-time order status updates: Pending → Accepted → Delivered Admin console (web or in-app) • View all incoming orders at a glance • Add / edit products and set delivery charges • Assign a delivery partner’s name to each order Expected deliverables • Flutter source code, clearly structured and documented • Release-ready APK for Android 12+ • Simple, responsive admin panel linked to the same Firebase or MySQL back-end you prefer • Basic deployment guide so I can update products, charges, or partners myself Keep the design clean and uncluttered, prioritising Hindi readability and quick checkout. If anything in the spec needs clarification, let me know before you start so development stays smooth and on target.
