Flutter vs. React Native: Which Should You Select?

Building an app for both Android and iOS is prohibitively expensive for many businesses. Thus, the concept of developing cross-platform mobile applications emerged. They are less expensive to develop and perform similarly to actual native programs. However, before beginning the development of a mobile application, you must select a technology stack. Currently, there are two formidable cross-platform development frameworks: React Native and Flutter.

In this article, we evaluate Flutter and React Native side-by-side to assist you in deciding which one is ideal for your project.

Developing with Flutter

Google’s Flutter is an open-source UI software development kit. It is used to develop cross-platform apps for mobile, web, and desktop platforms utilizing a single codebase. It should be emphasized, however, that the API for building desktop applications with Flutter is still in the development phase. Google is trying to enable developers to create applications for Windows, Linux, and macOS using Flutter.

Flutter is built on the object-oriented programming language Dart. The syntax of Dart is intuitive for Java and JavaScript programmers because it supports the majority of object-oriented notions. Easy-to-follow documentation is accessible on the official Dart website, making it simple to get started with Dart.

Flutter’s widgets are rendered using its own high-performance rendering engine. Because of the widgets, Flutter applications have a superb “look and feel.”

There are two types of widgets: those with state and those without. However, the widgets are not adaptable, therefore the platform-specific customization must be performed manually.

The Hot Reload feature enables developers to modify the codebase in real time and relaunch the program. Typically, it takes (milli-)seconds for application changes to display. This feature allows developers to repair bugs and test out new concepts. Additionally, the feature facilitates developer-designer collaboration.

Developing using React Native

Facebook developed the open-source framework React Native. It is used to develop applications for iOS, Android, the Web, and the Universal Windows Platform, and allows developers to leverage React with native platform features. It is utilized by Instagram, Facebook, and Airbnb, among others.

React Native bridges components with Javascript in order to connect each to a native module and execute the appropriate operation. Additionally, it enables developers to construct a single codebase and makes programs compatible with both platforms. This method saves time and increases productivity on both platforms.

React Native combines hot reloading and live reloading into a new feature called Fast Refresh that enables you to receive near-immediate feedback for changes to your React components.

If you have experience with web development, getting started with React Native and switching to it is rather simple. Experience with native development will facilitate your understanding of the fundamentals.

Comparing Flutter vs. React Native

Below, we compare Flutter with React Native on the basis of the ecosystem, performance, and availability of documentation.

Ecosystem Evaluation

React Native is developed enough that most, if not all, major editors support it. React Native is the apparent winner when it comes to packages, as it contains significantly more packages than Flutter, although quantity does not always indicate quality. Additionally, it supports Hot Reload, which significantly enhances the development experience.

React Native was built two years before Flutter, so Flutter is unquestionably lagging behind. However, Flutter is swiftly catching up, and many critical packages are currently available for public use. Over 1,450 Flutter packages are available on the official Dart website.

Performance Evaluation

In terms of performance, it is difficult to declare a clear winner because to the numerous elements involved; in some circumstances, React Native may outperform Flutter, even if Flutter is generally superior.

The difficulty with React Native is that when developers construct hybrid applications, they encounter challenges with its architecture, libraries, and native components, but developers of native applications are unlikely to encounter performance-related concerns.

In addition, React Native permits communication between JavaScript and the native language via the JavaScript bridge, therefore there is a possibility of a laggy UI due to the impact of the bridge on rendering speed.

React Native, on the other hand, has significant code reuse across platforms and provides numerous libraries that can be utilized as development building blocks. In addition, React Native enables Hot Reload, which allows you to view application changes without recompiling. React Native’s approach is distinct from Flutter’s. The apps of Flutter are compiled with the ARM C/C++ library so that it is closer to machine language and provides improved native performance. It’s not just a matter of building UI components.

Dart is a high-performance programming language, and most people feel that Flutter has more advantages than React Native. However, it is impossible to say definitely because there are so many variables.

Flutter does not require a bridge to connect with native components, hence its performance under same settings is superior. It contains everything, including frameworks such as Cupertino and Material Design. On multiple platforms, Flutter applications are more stable and predictable than React Native applications. In addition, it handles a number of challenges on its own thanks to Skia Engine.


Flutter provides useful and comprehensive documentation. However, if you have no programming knowledge, it may be a bit tough to read, but once you get used to it, you should be able to find almost anything you require.

The documentation for React Native is quite good and more user-friendly. The official documentation also contains how-to guides and common themes in cross-platform programming with React Native, such as how to install and use native modules and construct platform-specific components.

React Native includes documentation that describes the properties, what they represent, and how to use them. However, the framework relies heavily on external development kits, for which you will need to visit third-party websites.

Which Should You Select?

Both Flutter and React Native are cross-platform, which reduces time to market. Both are effective for cross-platform application development and provide several third-party libraries and ready-to-use components that further accelerate the development process.

However, because each application is unique, it is always advisable to discuss your idea with a team of seasoned engineers. They will evaluate your business’s needs and recommend alternative ways.

With a heavy emphasis on mobile app development, Reactjs Development Company assists its clients in the creation of superior cross-platform applications. Consult with a leading ReactJS development company to understand how to bring your idea to life in the most effective manner and how much it will cost to develop your application.
