The choice between React Native (RN) and Flutter depends on factors such as popularity, industry adoption, and long-term viability. React Native is more established and widely adopted in the industry, with more job openings and strong React.js ecosystem overlap. It is used by big companies like Meta and is popular for MVP development. Flutter, released in 2017, is growing rapidly and is used by companies like Google, Alibaba, BMW, eBay, Toyota, and ByteDance. React Native has higher demand in Western markets and is easier to transition from React.js. Flutter, on the other hand, is growing rapidly, especially in Asia and Latin America, and has Google's backing, making it a potential competitor.
