Flutter vs. React Native: What’s the Difference?

Mobile app development has experienced a significant transformation, primarily due to Flutter and React Native. These cross-platform app development frameworks have revolutionized the sector, providing developers with efficient tools to create stellar applications. Let’s comprehensively compare Flutter and React Native, highlighting the significant differences that define these two frameworks.

Let’s dive into the details of each difference.


Flutter uses Dart, a modern, purposeful language with an easy-to-understand syntax. Dart allows developers to craft intuitive, high-performing applications with minimal hassle. It supports object-oriented concepts, providing an easy transition for developers familiar with Java or C++. The Dart ecosystem is rich, boasting an impressive collection of libraries and tools.

On the other hand, React Native is JavaScript-based. JavaScript is one of the most widely used languages, making React Native more accessible to many developers. Moreover, JavaScript’s vast ecosystem brings an abundance of libraries and frameworks to developers’ fingertips. The flexibility of JavaScript allows React Native to integrate with other platforms, adding to its versatility.

User Interface

User Interface (UI) development is a significant factor. Flutter is bundled with a rich set of UI components called widgets. These widgets make UI development in Flutter incredibly smooth, enabling the creation of highly responsive and visually appealing applications. Furthermore, Flutter’s widgets are adaptable to different platforms, ensuring consistency in design.

React Native relies on native components for UI development. It leverages JavaScript and React to build interfaces, allowing developers to create components once and use them across different platforms. This approach promotes code reusability but might fail to provide consistent UI across other operating systems.


Flutter directly communicates with the native platform without any intermediary, which enhances its performance. Moreover, the Dart language is compiled into native machine code, which aids in optimizing the app’s execution speed.

React Native, while still maintaining good performance, might not be as efficient as Flutter. It employs the JavaScript bridge for communication with native modules, which can lead to performance bottlenecks. Nonetheless, React Native still delivers satisfactory performance for most application needs, and its widespread adoption attests to its efficacy.

Flutter excels in this area, providing well-structured, comprehensive, and easy-to-navigate documentation. It includes interactive examples, tutorials, and clear instructions, aiding developers at every step of application development.

React Native, while offering helpful documentation, is a bit unorganized compared to Flutter. It relies on its vast community to fill gaps in official documentation, leading to scattered resources across the internet. While this approach adds to React Native’s dynamism, it might pose challenges for developers seeking structured guidance.

Community Support

The strength and engagement of the developer community play a pivotal role. React Native boasts robust community support, owing to its inception by Facebook and earlier entry into the market. It has garnered a substantial following since its launch in 2015, and its wide adoption has resulted in abundant resources. Developers can turn to countless forums, blogs, and tutorials for help, and there’s a higher likelihood of finding pre-built components or libraries to accelerate development.

In contrast, Flutter, Google’s brainchild, while not as seasoned as React Native, is not far behind in community support. Despite its relative novelty, the Flutter community has been increasing, with more developers embracing it due to its unique capabilities. Google’s reputation and support for Flutter have been significant catalysts for this growth. Developers can find a wealth of knowledge in various Flutter dedicated resources, though it may not be as extensive as the React Native library collection.


As for popularity, React Native edges out Flutter. Being around longer, React Native has had time to mature and expand its user base. Its widespread use by tech giants like Facebook, Instagram, and Airbnb has contributed to its popularity among developers and businesses. Numerous success stories around React Native have further propelled its popularity in cross-platform development.

However, in its relatively short lifespan, Flutter has also made quite a splash in the tech world. Google’s backing and its novel approach to cross-platform development have helped it gain traction swiftly. Companies like Alibaba, Google Ads, and eBay have employed Flutter in their mobile applications, showcasing its increasing acceptance. Although Flutter still has some catching up to do, its growth trajectory indicates a promising future.
