User Interface

Flutter’s customizable widgets offer a high degree of flexibility, enabling developers to create visually stunning and responsive interfaces. React Native’s UI components closely resemble native elements but might require additional customization for a polished look. Flutter’s “hot reload” feature allows real-time UI adjustments, which can significantly speed up the development process.

Programming Language

Flutter uses Dart as its programming language, which might require developers to learn a new language. React Native relies on JavaScript, a widely-used language among developers, making it more accessible to a broader audience.

Ecosystem & Community

React Native has been around longer, leading to a larger community and a plethora of third-party libraries & modules. This can expedite development by providing solutions to common challenges. However, Flutter’s community is rapidly growing & it benefits from Google’s support, ensuring consistent updates and improvements.

Development Time

Flutter’s “write once, run anywhere” approach can potentially reduce development time, as the same codebase can be used for both iOS and Android platforms. React Native offers a similar advantage, but slight adjustments might be needed for platform-specific elements.

Popularity & Adoption

Both frameworks have gained popularity, with major companies adopting each for their apps. React Native’s head start gives it an edge in terms of adoption, but Flutter’s modern approach and performance benefits are rapidly attracting developers & companies alike.


Crafted by Google, Flutter stands as an open-source toolkit for UI software development.
