Flutter vs React Native: Which is Better for Cross-Platform App Development?


React Native is an open-source framework from Facebook. Flutter is a mobile app SDK from Google. Both the cross-platform app development tools from two software giants boast distinct features. It is hard to say which is the perfect choice for all circumstances.

React native was launched in February 2015 at Facebook's React.js Conf. The open-sourced edition was released in March 2015.

Flutter was introduced to the world by Google at the Google I/O Developer Conference 2017.

Since it was released two years before Flutter, React Native was able to garner popularity among developers quickly. Built on HS meant there was no dearth of talent which ensured its quick growth.

But, with the launch of Flutter things took a U-turn. Flutter promised several features that most developers felt were missing in React Native. Thus began the confusion and the comparison of both frameworks for mobile app development.

If you are someone who is in talks with a mobile app development company to build a mobile app using Flutter or React Native, then this blog is for you.

Flutter vs. React Native: Battle Of The Best Mobile App Development Framework [Infographic]

flutter vs react native performance comparison. The battle of the best cross platform mobile framework

We took a deep dive into the various features that both Flutter and React Native have so that you don’t have to spend hours doing the comparison.

By the time you are done reading this blog, you will know which platform is best for which scenario.

Let's get started.

#1 The Language Stack

React Native is built on JavaScript, so you will have to be an expert on JS to make the best use of it. All dynamic JS code is compiled in native view at runtime, while the rest of the code is pushed to a virtual machine.

Flutter uses Dart. Dart is a general-purpose programming language that Google itself developed and launched in 2011. Dart as a programming language allows developers to create stunning mobile apps bolted with high-end features for all platforms, including Android, iOS, and also the web.

#2 Architecture

React Native is based on an application architecture known as Flux. Flux is the same architecture that Facebook uses for building client-side web applications. The crux of Flux is its unidirectional data flow. While React handles the view part, Flux handles the Model in the MVC.

Flutter also has Flutter Flux, a Dart app architecture library with unidirectional data flow that is inspired by RefluxJS as well as Facebook's Flux. The only difference being the components included in the data-flow pattern like Actions, Stores, and StoreWatchers.

#3 Performance

React Native can run into a few problems when building hybrid mobile apps. This is primarily because of the JS Ecosystem and its many variants. However, when it comes to building native mobile apps, React Native promises rock-solid performances and high reliability.

Flutter, thanks to its Dart language offers a seamless mobile app development setup. It weeds away all the hassles that often accompany hybrid mobile app development. As a result, the time taken to build and launch a mobile app using Flutter is drastically low. The animation standard at 60fps is a testament to that fact.

#4 User Interface

React Native does not have its own UI components library. So, you will have to rely on third-party libraries to create your own custom user interfaces.

Flutter, on the other hand, has layout widgets that can be used for a variety of uses. The UI boasts impressive elements like rich motion APIs, built-in material design, iOS-flavor widgets, and much more. The scrolling is also far smoother than React Native. Some of the Flutter widgets include Drawer, Inkwell, GestureDetector, and DefaultTabController.

#5 Support

The 2 years ahead of release have helped React Native build an active community of developers and enthusiasts. It is ranked as one of the most popular frameworks in Stack Overflow and also has a GitHub base with 68K stars. Other platform populations 14.5K users subreddit and ~9000 users on Discord.

Flutter may not have a strong social backing as React Native, but Google’s support is nothing less than extraordinary. It’s Github stars count to ~25,000, has around ~2,500 stack overflow questions and a ~4,000 odd user community. In fact, the technical documentation does a great job of explaining everything that a developer would want to know while using Flutter for app development.

#6 Time taken for Development

React Native, with the help of many third-party libraries like Calendar, Carousel, and Modal helps reduce the overall time taken for app development.

Flutter allows for 70% of code reuse, which means you can build iOS, Android, and web apps in the shortest time span possible.


React Native and Flutter are two popular mobile app development frameworks.

But, after the above comparison, we can lean towards Flutter as a preferred choice for cross-platform mobile app development.
