I’m gearing up to launch a ride-hailing service and need a turnkey Flutter solution that covers every side of the business. The work includes a Rider app and a Driver app for both iOS and Android, plus a responsive web Admin panel. Core functions I expect from day one: • Real-time driver location tracking, continuous ride-progress updates, and accurate ETA calculations • Yandex map integration as the primary mapping service (if you can demonstrate stronger value with Google Maps, Mapbox, or OpenStreetMap I’m open to discussing) • Secure in-app payments with mainstream gateways—tell me which you’ve already deployed and how you handle PCI compliance • Live ride status, push notifications, rating & review flow, promo code logic, and a dashboard that lets me monitor trips, drivers, and payouts in real time Because the launch timeline is tight, an existing white-label package you can customise quickly is welcome—just share a working demo or public store link so I can try it out. If you’re proposing a fresh build, show screenshots or videos from past taxi or delivery apps built with Flutter to prove your workflow and code quality. My budget is flexible and will scale with the stability, scalability, and polish of your solution. When you reply, please outline: 1. A high-level architecture or tech stack overview 2. Key milestones with realistic delivery dates 3. Any post-launch maintenance or hosting options you offer I’m ready to move fast once I see a proven, end-to-end solution that matches the feature set above.
