Too Long; Didn't Read
React Native and Flutter are cross-platform platforms used to build mobile applications that work on both IOS and Android platforms. Google and Facebook are already competing in the web community. Both platforms use different languages and procedures to build apps that behave similarly. The programming language used in React Native is Javascript. The performance of React Native’s architecture is poor as compared to the Flutter's because of the javascript bridge used in the former. Flutter uses Dart, which in turn uses the Skia C++ engine.
