Flutter vs React Native
Both Flutter and React Native framework is used to build cross-platform mobile apps.
Now in 2022, the big question is which one is best?
we don’t recommend being selective in choosing the right technology framework — be it native, React Native or Flutter, this article will put some limelight to use a more defined approach instead.
What is Flutter? It is an interface-building tool that uses the Dart programming language. In other words, it’s a Google UI framework.
Flutter targets desktop, mobile, and web platforms from a single codebase and features its own Dart native compiler to create hardware-optimized apps for the ARM architecture.
What is React Native? It is a Facebook-led native UI development framework, based on React.JS. It’s open-source and was at the peak of its popularity in 2018, React Native GitHub repository was the top second judging by the number of community contributions.
Which is More Powerful and Efficient?
Our colleagues from The Startup community on Medium shared a decent performance study of native and cross-platform approaches in mobile app development. They ran multiple tests on real Android and iOS smartphones and compared the execution time for Pi-digits calculations implemented with Flutter, React Native, and Native programming languages (Swift/Obj-C for Apple, Java/Kotlin for Android). Check out the unexpected results in the table below.
No doubt, the highest performance in any programming task is the distinctive advantage of native mobile development. However, with cross-platform frameworks, everything isn’t very straightforward. Flutter demonstrated just 9-22% lower performance in memory-intensive tests in comparison to Native. Although in compute-intensive tasks it is 2-6 times slower than Native. React Native showed the worst performance in all the tests. It’s 2-15 times slower than Flutter and 5-21 times slower than Native. Editorial notice: benchmark tests depict only very narrow characteristics of the technology performance. In the completed real-world apps the difference in performance is aligned and isn’t correlating with the deviations in benchmarks. Although, the general trend remains the same: which technology is better in tests usually performs better on live too. To explain this contradictory output, let’s take a look at the architecture and operational principles of both frameworks.
