React vs Flutter: Choosing the Best Cross-Platform Framework

When it comes to app development, choosing the right framework can feel like navigating a labyrinth. Every move is an opportunity to make a choice and every choice may greatly influence the result of the project.

Cross-platform app developers can now rely on React and Flutter to build powerful applications, but which one is better to choose? But for this post let’s briefly discuss the strengths, differences, and application of both perspectives in a conversational style.

React vs Flutter

Once upon a time, developers had to choose between building separate apps for iOS and Android or sacrificing quality for cross-platform functionality. Then, frameworks like React Native and Flutter came into the big scene, which were capable of providing powerful applications on multiple platforms through a single code.

React Native

React Native is actually a framework for the React JavaScript library developed by Facebook for building interfaces. It enlarges upon the functions that React offers and can be used for mobile application development and its design is akin to React.

It means if you’re looking to hire React developers, you’re essentially gearing up to use a framework that maximizes code reusability and simplifies the development process for iOS and Android apps.

Key Features

  • Learn Once, Write Anywhere

React Native focuses on the philosophy of learning a single way of building applications and translating that knowledge into multiple platforms.

  • Rich Ecosystem

Being based on JavaScript, React Native benefits from a vast ecosystem of libraries and tools that developers can integrate into their apps.

  • Strong Community Support

Thanks to its maturity and backing from Facebook, React Native enjoys strong community support, with numerous tutorials, forums, and third-party plugins available.


Since it was developed by Google, Flutter has sparked a great deal of interest. The framework can create beautiful and natively compiled apps for desktop, mobile, and web from a single source code. It works with Dart – a language created by Google, that is rather simple to learn. Particularly if the user has prior experience with other programming languages.

Key Features

  • Everything is a Widget

Flutter’s design revolves around widgets, the building blocks of a Flutter app. It helps in developing a UI that is highly customizable and can be implemented and reused frequently.

  • Hot Reload

This characteristic allows the developers to see whatever changes they are making in the code in real-time. It cuts the development time.

  • Impressive Performance

Flutter apps are compiled directly into native code, which helps achieve performance indistinguishable from native apps.

1. Performance

When comparing React Native and Flutter based on performance, Flutter often takes the lead. The ability of Flutter to compile native code without the bridge that React Native uses generally results in faster app startup times and smoother performances.

However, React Native is no slouch; with the right optimization, React Native apps can rival native apps in performance.

2. Simplicity and Familiarity

For developers who are already familiar with JavaScript, diving into React Native is a breeze. The learning curve is relatively small and the fact that it is possible to build a website using existing web development experience makes it rather popular among the companies.

On the other hand, Flutter has its own language, Dart. This language may require a bit of learning, but Dart is straightforward for anyone with basic programming knowledge.

3. Tooling and Documentation

Google’s Flutter excels in its documentation and tooling. Extensive and structured documentation is beneficial for newcomers since it helps them quickly join the team. React Native, while having good documentation, sometimes relies on community-driven content, which can be inconsistent.

4. Real-World Applications

Many brands, including Facebook, Instagram, and UberEats, have utilized React Native, which is indicative of its stability and adaptability. Flutter, while newer, has been adopted by companies such as Alibaba and Google Ads for its performance and aesthetic flexibility.


The choice between React Native and Flutter can depend heavily on your specific needs:

  • Choose React Native if you have a team familiar with JavaScript, value a large community, and want to start quickly with a minimal learning curve.
  • Choose Flutter if you value a flexible UI and great performance or if you have plenty of good documentation to study to find your way around.
