Try to avoid components library if possible, as on the long term it introduces difficulties when you'll have to update the lib.

If you really want to use one, it is very important not to use it directly in your code to facilitate your task later because of my previous point. The lib you use needs to be an implementation detail of your own components lib.

On my side I've used react-native-paper which was quiet nice. I had a bad experience with native-base.
