The main differences between Flutter and React Native are:
Programming Language
Flutter uses the Dart programming language, which is less widely used than JavaScript but has a simpler syntax that can make the learning process faster for developers new to mobile development[1][4].
React Native uses JavaScript, which is more popular and has a larger community[1][4].
Architecture
Flutter uses a Business Logic Component (BLoC) architecture, while React Native uses Flux and Redux architectures[3].
Flutter's architecture is designed to be more intuitive and easier to understand than React Native[1].
Performance
Flutter is typically faster than React Native because all Flutter processes are fully native, while not all actions in React Native are performed natively[1][4].
Flutter apps are usually "bigger" than React Native ones due to the C/C++ engine, but the larger size doesn't negatively impact performance[1].
App Size
Flutter apps are typically larger than React Native apps due to the C/C++ engine[1].
However, the larger size of Flutter apps doesn't significantly impact performance, as the extra features that take up space also make the app faster[1].
Debugging
Both frameworks are relatively easy to debug, with React Native using React Native Debugger and Chrome DevTools, while Flutter uses the Flutter Doctor command-line tool[1].
Flutter's debugging environment can be tricky to get used to compared to other platforms[...
