This is the customer app for the Modern Aqua water-delivery company: users choose drinking water and accessories from a product catalog, manage their cart, and place orders by setting a delivery address on the map. The app covers cash and online card payment, an e-wallet balance and bonus system, order history and status tracking, product reviews, and real-time chat with the courier. It is built on Flutter with a BLoC/Cubit architecture, integrating Firebase, Google Maps, and real-time communication.
