Native applications work without a hitch on smartphones, and their data and graphic transformation reduce UI rendering compared to cross-platform development. Their codes can help communicate straight to the mobile OS code by allowing all possible UI methods, and it could be one of the justifying reasons. On the other hand, native mobile platforms (OS) are written in distinct languages. For example, Android OS is a blend of C, C++, and Java.

In comparison to this, the iOS platform is developed over Swift and Objective C. Thus. One would require to know languages like Java and Swift for native mobile development. It can be a huge deal for some companies as everyone cannot afford to hire a top to react native app development company for each platform.

While we discuss cross-platforming, mobile applications are less competitive, though it is pretty hard to observe it at first glance. However, these are economical and effective and can be an excellent fit for your company. Facebook was the first player to announce React Native in the market. Simultaneously the cross-platforming development also turns out to be accurate as one can develop the code once, and it turns to native designs. The next significant event that happened in 2017 was the announcement of Flutter. Google was the one to announce Flutter, and it was based on the Dart programming language.

Here in this article, we will learn in detail about React Native and Flutter. Further, we will analyze their performance for both platforms, and let’s see who wins the battle of Flutter vs. React Native.

Flutter Vs React Native: Performance

It is quite debatable to discuss the difference in the performance of Flutter and React Native. Individual communities for both Flutter and React Native are a bit divided as everything they provide is excellent in terms of agility and speed. However, RN has faced a lot of criticism for its performance due to the involvement of third-party libraries and native modules. So let us get into details and learn about Flutter vs React Native for beginners. It would be recommended to consider the elemental “hello world.” App with a straightforward image with both Flutter and RN. Read

☛ How does React-Native Perform?

React Native still has some scope of performance improvement in comparison to Flutter. It is because JavaScript tends to bridge the communication difference between native modules. For every interval, the amount of frames released in the React Native “hello world” app is much higher than Flutter. While in some cases, the app looks more extended than 16 milliseconds to provide the program making the application shitter. One can improvise the app’s performance by integrating third-party libraries like prop guard to optimize the bytecodes. React Native has elements like Slowlog that helps in setting performance timers that would track the performance issues and resolve them.

☛ How does Flutter perform?

Flutter has a better performance graph than React Native as it does not focus on bridging the gap between native modules. They lack this aspect because of their default availability of native components. The performance test pointed out that the “hello world” app used to perform at 60 FPS consistently. Further, the time utilized to render each frame does not take more than 16 milliseconds. At the same time, the number of frames that were dropped was more minor in comparison. As discussed earlier, Flutter uses the Skia graphics library to permit the UI to be redrawn with each modification in the application view. Undoubtedly Flutter performs much more efficiently, even at 60 FPS. Read more on why Flutter is a future of cross platform app development.

Flutter Vs React Native Code Comparison

React native undoubtedly has one of the most significant communities and support. Still, various issues are being faced while maintaining the language of your application. On the contrary, it is much more convenient to manage Flutter than React Native.
