React-Native has two significant pros that Flutter doesn't have.
Native UI. I heard multiple times now that Flutter drains the battery rather quickly because it doesn't use the highly optimized native UI elements.
JavaScript. There are more JavaScript developers out there than .NET ones. Also, the JS devs are much cheaper.
Another interesting pro is, you can use RN to develop basically everywhere. Expo (a RN framework) announced Web support, so you get Android, iOS, and Web out of the box. Microsoft announced UWP support and rewrote react-native-windows.
