Any views on Should I learn react native or flutter?
Flutter uses Dart language which is very interesting and easy to learn.
You are new and looking to learn then Flutter may be the better idea as currently, Github Flutter Cross React native.
Flutter: https://github.com/flutter/flutter It has approx 85000 Star of GitHub.
React Native has 83000 Start on Github.
React native is great but if keeping future in mind that in coming 2-3 year flutter may go way ahead then react native.
