RideMate is a Flutter-based ride-sharing mobile application designed to connect travelers with bikers offering rides for short and medium distances. The application focuses on providing a safe, affordable, and eco-friendly transportation solution, especially for daily commuters. The app supports dual user roles—Traveler and Biker—allowing users to seamlessly switch roles using an animated toggle. Travelers can search for available rides by selecting pickup and drop locations, while bikers can post rides with details such as route, timing, and ride type (one-way or two-way). RideMate emphasizes user safety by incorporating features like verified biker profiles, gender-based ride preference, and an SOS emergency button. The application also includes ride request and acceptance flow, trip history tracking, in-app chat, and a wallet system for bikers to manage earnings. Built using Flutter for cross-platform compatibility and Firebase for backend services, RideMate demonstrates real-world mobile app development concepts such as navigation, UI animations, cloud data storage, authentication, and map integration. The project is designed to be scalable, with future enhancements planned for live tracking, online payments, push notifications, and AI-based ride matching.
