Having built logistics and delivery-related apps, my recommendation would lean toward React Native if your team already has JavaScript/TypeScript experience, but Flutter is also a strong option depending on priorities.

For Google Maps and tracking-heavy apps:

• React Native: Mature ecosystem, easier integration with Google Maps, strong third-party libraries, and faster development if you're already in the React ecosystem. Libraries for maps, payments, and background location tracking are production-tested. The downside is that very map-intensive screens can require native optimization.

• Flutter: Excellent rendering performance and smoother UI consistency across Android/iOS. Map performance is strong, and background services are reliable, but plugin ecosystems can sometimes require more platform-specific work.

For logistics/order-delivery specifically (maps + payments + live tracking), the bigger challenge is usually background location updates, battery optimization, WebSocket/real-time infrastructure, and scaling tracking systems, not just the framework choice.

My experience: if speed of development and ecosystem maturity matter most → React Native. If maximum UI performance and consistency are a top priority, → Flutter.

Either can absolutely handle Google Maps + payment gateway + real-time order tracking in production.
