Flutter Vs React Native

Flutter Vs. React Native

Flutter Vs. React Native: Key Points
From being open-sourced, fast and free to offering excellent UI support and native-like experience, React Native and Flutter, two major competitors offering cross-platform solutions, share various similarities. However, there are certain aspects of these two frameworks that make one framework superior from the other, which will be highlighted in the following comparison:

Programming Languages: Flutter Dart vs React Native JavaScript
A major advantage of using cross-platform mobile app development frameworks is it allows developers to create applications for both iOS and Android using a single programming language.

Flutter uses Dart programming language to create a Flutter app. Though new for mobile application developers, Dart is easy-to-use for developers experienced in different OOP languages such as Java and C++.
React Native: Uses JavaScript to build cross-platform apps. Extremely popular among developers, this programming language helps web developers build apps with little training and hence is a winner compared to Flutter.
User Interface:
As React Native is purely focused on UI design, it has a large number of React UI components that are more extensive than that of Flutter. This is because application development with React Native is highly based on native components, whereas Flutter works flawlessly with the owner widget sets. One advantage of these widgets is that they prevent the developer from being dependent on third-party UI libraries.

Development Time:
Development time and process are the two most critical aspects that need consideration during mobile application development. Flutter, prominently known for fast and simple development, is lauded for its hot reload feature, which enables developers to instantly view changes and implement modifications. Moreover, it provides a full suite of extensible components that are built from scratch. Whereas, React Native, though popular, relies heavily on third-party libraries, which becomes makes the process comparatively slower.

React Native Vs. Flutter Performance:
React Native, though popular for providing high-quality user experience, is considered less suitable for application development because of its architecture, which impacts its performance and makes it slower. Whereas, Flutter’s ability to reuse the same code for creating applications for different platforms as well as its use of widgets and GPU to render it on apps on the screen helps create apps with best-in-class performance and speed.

Documentation & Toolkit:
Google, like always, provides clear, structured, and in-depth documentation for their products, with Flutter being no exception. From installation to widgets, testing, more Flutter offers proper documentation for all and is backed by the Flutter team. React Native lags behind in this aspect, as it has a poorly maintained and unclear documentation, with not much explained like installation and configuration setup. Moreover, it lacks official documentation for Continuous Integration & Continuous Delivery (CI/CD).

Technical Architecture:
Another important aspect that needs consideration when comparing React Native and Flutter is technical architecture.

Flux Architecture:
As React Native relies heavily on JS runtime environment architecture known as JavaScript bridge, it uses Facebook’s Flux architecture, which helps it to communicate with native modules. This though beneficial results in poor performance.

Skia:
On the other hand, Flutter uses Dart Framework, which has most of the components inbuilt and does not require JavaScript bridge to communicate with the native UI component. Moreover, it further uses the Skia C++ engine which consists of all the protocols, compositions, and channels needed to develop a mobile app. This independency of Flutter makes its architecture more beneficial than React Native.

DevOps and CI/CD Support:
To ensure an application receives continuous feedback and is not released with bugs, it crucial to adopt Continuous Integration and Continuous Delivery practices. This is ensured by Flutter, in its section on Continuous Integration and Testing, where its rich Command Line Interface (CLI) allows easy set up on CI/CD services strong CLI tools, whereas, React Native does not provide any instructions on CI/CD practices.

Installation:
The installation process with Flutter is more straightforward, with the added advantage of automated checkup of system problems. On the other hand, react-native lacks a streamlining setup and configuration.

Development Tools:
Some of the tools used in both React Native and Flutter mobile application development are:

Flutter:
Flutter SDK.
DevTools.
Hot Reload.
React:
Expo.
Redux.
Flow.
Ignite.
React Navigation.
Conclusion:
React Native is currently ruling the spectrum of cross-platform mobile application development, however, there is no doubt that Flutter is working hard to prove its worth and is slowly taking over the future mobile application development, by making the development more streamlined, introduction of new features and functionalities, as well as by saving the developer time and effort. However, it is still too soon to answer to questions like “Is Flutter better than React Native?”, as Flutter is still climbing the ladder to achieve the popularity and reliability that React Native is currently enjoying.
