Flutter vs. React Native

Businesses need cross-platform mobile apps to reach diverse audiences across multiple platforms such as web apps, IOS, and Android. However, the key is to maintain user interface and user experience consistency across all platforms. 

As business owners head to computer programmers and mobile app developers with their requirements, developers must choose between Flutter, React Native, or other frameworks that best suit business requirements. Let us look at a comprehensive Flutter vs. React Native comparison from a developer’s perspective and how they can be best implemented to meet business objectives. 

Overview of Flutter

Google developed Flutter as an open-source UI software development toolkit in 2017. Developers can use a single codebase to create natively compiled mobile, web, and desktop applications with many libraries and resources. It uses the Dart programming language with a rich set of pre-designed widgets and designs for visually appealing applications.

Pros of Flutter

  • Rich widget and design library to create beautiful and complex UI.
  • Flutter-based apps are compiled into machine code that improves performance without needing virtual machines and interpreters.
  • The hot reload feature helps review changes in real time.
  • Maximum performance on ARM-based devices and smartphones with Dart programming language and ahead-of-time (AOT) code compilation.
  • Performance-enhanced Skia rendering engine can develop smooth animations and complex UI.
  • Low development cost as a single Flutter developer can handle both IOS and Android platforms.
  • Best for small mobile apps with low-cost deployment.

Cons of Flutter

  • Applications can have larger file sizes that cause storage constraints and increase installation time.
  • Downloading large packages can be costly and time-consuming
  • Dart programming language and widget-based architecture can take time to learn compared to those who already know JavaScript. 

Overview of React Native

React Native was developed and released by Facebook in 2015; it uses JavaScript and a robust React library to build high-performance UIs. Also known for its “write once, use anywhere” philosophy, it is a popular cross-platform development framework.

Pros of React Native

  • Many developers who work on React Native are already familiar with JavaScript-based frameworks. 
  • React Native has a vast community of developers with numerous libraries, plugins, and resources.
  • Live reloading with real-time change management for faster development.
  • Third-party plugin support with React Navigation, React Native Elements, Redux, Native Base, Axios, Moment.js, and React Native base for ready-made functionality, reduced development time, lower costs, and UI elements. 

Cons of React Native

  • High-performance bottlenecks with bridge overhead to help JavaScript communicate with native code. 
  • Delayed screen load and stuttering transitions if navigation code is poorly implemented.
  • Complex component hierarchies with the need to reconcile trees with frequent updates.
  • Only optimized images and efficient third-party libraries can lead to slow rendering. 

Developer’s Verdict

As a developer, Flutter vs. React Native is a difficult choice as both have merits like low cost of deployment, third-party support, and high-performance app framework that can be used to make beautiful UIs.

However, Flutter can be preferred over React Native due to its performance, rendering, and low CPU usage based on the native ARM codebase. The single codebase can be easily used across multiple web, desktop, and mobile platforms. It is also gaining popularity over React Native due to its debugging capabilities, Dart language syntax, and beginner-friendly approach over JavaScript. 


What are the critical differences between Flutter and React Native for developers?

Both use different programming languages. Flutter relies on Dart, while React Native uses JavaScript. However, Flutter provides better native performance and lower development times. Likewise, React Native has a mature ecosystem, while Flutter gets frequent updates from Google. 

Which framework offers better performance and user experience for mobile app development?

As per our experience, Flutter offers better performance due to native ARM compilation, a single codebase, and a rich set of widgets for high-quality user experiences. React Native could lag with slower rendering depending on the assets’ quality. 

How do Flutter and React Native compare in terms of community support and developer resources?

We believe React Native has a larger community with many third-party resource plugins and libraries. However, Flutter is catching up fast and gaining popularity for its speed and performance.
