React Native vs Flutter: Which Framework is Best for Mobile App Development

by admin

If you’re a mobile app developer, you’re probably always on the lookout for ways to create better, faster, and more efficient apps. In recent years, two popular frameworks have emerged as frontrunners in the world of mobile app development: React Native and Flutter.

React Native and Flutter are two of the most popular cross-platform development frameworks for building mobile applications. Both frameworks have their own unique features and advantages, and deciding which one is best for your project can be a difficult task. In this article, we will compare React Native and Flutter to help you make an informed decision.

Overview Of React Native And Flutter

React Native is an open-source framework developed by Facebook that allows developers to build native mobile apps for iOS and Android using JavaScript and React. It uses a combination of native components and JavaScript to create an app that performs like a native app.

Flutter, on the other hand, is an open-source mobile development SDK (software development kit) developed by Google. It uses the Dart programming language and provides a rich set of pre-built widgets that enable developers to create beautiful and highly performant apps for iOS, Android, and the web.

Performance and Development Experience

Both React Native and Flutter have their own strengths and weaknesses when it comes to performance and development experience.

React Native is known for its excellent performance and speed. It uses native components to build apps, which means that the app runs at a native speed. React Native also has a large and active community, which means that there is a lot of support available for developers. However, it can be challenging to debug React Native apps, and there can be compatibility issues with certain third-party libraries.

Flutter, on the other hand, is known for its exceptional performance and beautiful UIs. Flutter’s pre-built widgets make it easy for developers to create highly polished and beautiful apps that look and feel like native apps. Flutter also has a “hot reload” feature that allows developers to see changes to the code in real time, which can significantly speed up the development process. However, Flutter’s learning curve can be steep, and the language it uses, Dart, is not as widely used as JavaScript.

Community Support

React Native – React Native, released as open-source on GitHub in 2015, is the most popular framework on Stack Overflow and is backed by a vast community with over 310,507 tagged questions.  

Flutter – Flutter is a relatively new framework that has a smaller community. However, more and more developers are adopting it slowly. It has over 89,638 questions on Stack Overflow


React Native – React Native is entirely written in JavaScript using React. This is an advantage for React Native since JavaScript is one the of most popularly used languages in the world today. 

Flutter – Flitter is written using a language called Dart. Dart is a programming language introduced by Google in 2011 and is rarely used by developers.


React Native – React Native is widely adopted and is a more popular app development framework than Flutter. React developers can quickly develop react native mobile apps, which encourages more developers to use this framework. 

Flutter – Flutter is relatively new, and though it has gained some attention lately, it is still way behind in developer count. Since Dart is a new language, the adoption rate among developers is slightly lower.

User Interface

React Native – React Native is based more on native components for both Android and iOS devices. It offers an extensive collection of external UI kits that helps in creating beautiful user interfaces for your applications. 

Flutter – Flutter uses the proprietary visual, structural, platform, and interactive widgets. These widgets are built-in UI components that replace native platform components. 


React Native – React leverages JavaScript to connect to native components via a bridge. As a result, the speed of development and the running time is slower than Flutter. 

Flutter – There is no interconnecting bridge for initiating interactions with the device’s native components. Hence, interactions with native components are faster, improving the overall performance of the application.

Ease of Integration

When it comes to integrating with other tools and frameworks, React Native has the advantage of being built on top of JavaScript and React, which are widely used in web development. This means that it is easier to integrate React Native apps with web apps and web services.

Flutter, on the other hand, is relatively new and has a smaller community than React Native. However, Flutter has a growing number of plugins and packages that make it easier to integrate with other tools and frameworks.


React Native – React Native offers general documentation. The framework depends on external dev kits extensively. The documentation is not as straightforward as that of Flutters.

Flutter – It provides documentation that is easy to read, thanks to its format and detailed content. The documentation is also more streamlined and straightforward.


Both React Native and Flutter are powerful and capable frameworks for building mobile apps. Which one you choose depends on your specific project requirements and development preferences. React Native is an excellent choice if you want to build an app quickly and have a large community for support. Flutter is a great choice if you want to build beautiful and highly performant apps with a steep learning curve.

So, which one should you use for your next project? Keep reading to find out!
