I really recommend nativewind to solve pretty much every gripe I have with styling react native, if you still want to give it a chance. Expo for instant cross platform updates by just publishing updated JavaScript (no more publishing updatdes in app store and play store!) Also, yup and Formik for form validation and react query for API calls. With these minimal libraries react native becomes a beast.
I think it’s the same as any other platform. Right now the content in small communities is limited, but over time once there is a sizable amount of content that newcomers can get referred from or go through, Lemmy as a whole will get more traction. Since the Reddit exodus happened I definitely feel like Lemmy has grown a lot and I’m here for the long run.
