For cross-platform software development, ‘Flutter’ and ‘React Native’ are the two best solutions available in the market. Their popularity has been on the rise for a few years and for all the right reasons. Both of these technologies allow the users to develop apps with a single code base.
Whether the system being used is iOS or Android, the development using these apps is very fast and smooth. These technologies have revolutionized the app development landscape as the apps can be released quicker than ever with a small price to pay.
This blog will dive into the detail of why users might prefer Flutter over React Native for modern app development.
Flutter is a UI toolkit created by Google that can enable developers to come up with apps for mobile, web, desktop, and embedded devices using a single codebase. A single codebase requires the developer to write the code only once that will work on all platforms.
Flutter uses an object-oriented programming language called Dart. It has built-in support for highly customizable UI widgets. Apps built with this toolkit are very fast in performance as the Flutter SDK compiles the code written in Dart into native platform-specific code. Flutter also offers a very handy feature for developers called ‘Hot Reload.’
Flutter Vs. React Native: A Comparison:
Although both of them offer more or less same features, there is a huge difference in how both frameworks work behind the scene and their overall impact on performance.
Mechanism of React Native:
It not only slows down the app, but also uses extra hardware resources. To address this issue, React Native uses Virtual DOM, which minimizes the amount of data exchange via bridge.
Mechanism of Flutter:
Flutter, which was created two years after React Native, took a totally different approach and avoided the bridge altogether. Flutter compiles dart code into platform specific native code (which means there is no bridge for two different languages to communicate, just pure native code).
Flutter has its own widgets and a powerful rendering/graphics engine called Skia. It only uses the canvas of the relevant platform (iOS/Android) to draw widgets on screen. It means that Flutter has full control over screen and everything is highly customizable since it doesn’t depend on the native widgets.
A button drawn on screen using Flutter will look the same in Android, iOS, or any other environment (regardless of old or new OS version), unless you configure it to look different in each environment. In case of React Native, it will look different in Android, and different in iOS.
It can also look different in different versions of the same OS because when you get updates on your mobile phone, some UI elements also change with those updates.
In comparison, Flutter is much faster than React Native. It is also less expensive, offers better performance, and has better compatibility with both iOS and Android than React Native.
