Flutter vs React Native: A Detailed Comparison

Here, we will compare Flutter vs. React Native based on some of the most important aspects:

Programming Language

Flutter is based on Dart and has entered into the mobile app development industry after React Native. For years, React Native has remained the go-to language of many developers to create mobile apps. However, Flutter has gained much popularity and is now considered one of the best cross-platform app development frameworks.

One of the daunting questions in the developer community is; Flutter vs React Native: what to choose for mobile app development? The first parameter that every developer looks at when choosing a framework is the programming language.

Google introduced Flutter in 2017, which uses the dart programming language. And since then, it has become famous. Dart is based on object-oriented languages like C/C++, Java, and JavaScript. Hence, any developer familiar with these languages can quickly start their journey with Dart. Moreover, Dart comes with AOT (ahead-of-time) and JIT(just-in-time ) compiler. Hence, it is 2x faster than JavaScript.

On the other hand, React Native is heavily dependent on JavaScript. It is suitable to develop apps that run on multiple platforms. Developers who are familiar with JavaScript can initiate their journey with this framework. Lastly, JavaScript is highly popular among developers, and it is also the primary language among various browsers.

Technical Architecture

Technical architecture is one of the most important aspects of a mobile app. It helps you to determine the business growth and scalability.

Comparing Flutter with React Native, it possesses a layered architecture that offers a lot of customization. On the contrary, React Native depends more on the JS runtime environment. It is also referred to as a JavaScript bridge to build communication with the native UI modules. Communication with the Native UI is possible with the help of JSON messages and Flux architecture built by Facebook.

Flutter utilizes the Dart language that consists of a vast number of built-in UI components. Therefore, developers do not have to rely on the JS bridge for any customization. Further, the dart language uses a Skia engine that comprises various protocols, compositions, and channels. Hence, developers can control most things on the screen while building Flutter apps. Also, developers can include animation, text, graphics, and more effectively into the apps.

React Native mobile app architecture utilizes JavaScript core inside the android app while it utilizes JS Core separately in iOS to run the codes. However, the use of a bridge in React Native increases app size and reduces the performance of the app.

Installation and Configuration

Developers consider installation & configuration as one of the major points while choosing a cross-platform framework. Comparing Flutter vs. React Native based on the installation, we can say that React Native is easier to install. How?

The reason is that the developer does not need to have a comprehensive knowledge of JavaScript to carry out React Native installation. But it also has a drawback; it doesn’t offer a detailed installation guide.

On the other hand, the installation of Flutter is somewhat complex and consumes more time. Here, developers have to download a binary for a specific operating system.

A developer without knowledge of Dart can complete the installation. One of the benefits of Flutter is that it offers an in-depth installation guide. Moreover, it provides a CLI tool known as Flutter doctor to install and configure things effectively.

Performance

Comparing the Flutter vs React Native performance, mostly Flutter is considered superior to React Native. However, the performance depends on a lot of things.

Flutter uses C++ to compile the mobile application. Hence, it offers enhanced performance. Moreover, it can resolve many issues and provide an excellent User Experience (UX). It can handle CPU-heavy operations, and it possesses a powerful memory. If you want to integrate beautiful animations and make an expressive UI for your app, Flutter offers the best performance.

In React Native, the entire application isn’t compiled using the C++ or native language. Instead, the UI components are compiled with the help of native equivalents, and the JS works with various threads and communities to execute any task via bridge. Hence, React Native offers very good performance compared to many other cross-platform frameworks such as Ionic. However, React Native is slower than Flutter.

Besides this, when you compare Flutter vs React Native performance considering the Hello World program, Flutter wins the race.

The performance test of the Flutter indicates the Hello World program takes only 60 FPS to operate efficiently, and it requires only 16 ms to render all the frames. Moreover, the main target of Flutter is to offer 60 FPS or 120 FPS performance on all devices that can handle 120Hz updates.

React Native is slower because it requires a JS bridge to interact with the native modules. Moreover, the total number of frames dropped in React Native’s Hello World program is way more than Flutter.

Several times, React Native took higher than 16 ms to render a program used in the application. Hence, the developer needs to rely on various third-party libraries to enhance the performance of the application.

Learning Curve

Many developers worldwide check the learning curve of cross-platform frameworks before choosing a suitable one. React Native is easier to learn as compared to Flutter.

Anyone familiar with JavaScript or React can quickly get started with React Native. Moreover, there are many tutorials, comprehensive modules, and libraries released on React Native. Hence, developers find it easy to learn about this framework.

On the other side, Flutter has a steep learning curve. A developer needs to know JS/ Java/ Kotlin/ Swift/ C to get started with Flutter. Even if one does not have knowledge of these languages, they can get started with Flutter as it offers excellent documentation.

Community Support

For building any mobile application, the support of a community helps to resolve any issues quickly & effectively. Both React Native and Flutter have evolved over the last couple of years and are constantly releasing technological updates as per the requirement. Hence, the popularity of each framework is increasing exponentially. Let us go deeper to know which framework has a large community, Flutter or React Native?

Flutter language has been in the industry for a long time; however, it got traction after Google announced it at the Google I/O conference in 2017. React Native is an open-source library released by Facebook in the year 2015.

The popularity of Flutter increases because Google organizes various meetups, hackathons, and other events online and offline every year. Similarly, there are many meetups and conferences conducted around different cities worldwide by the React Native community.

Even though Flutter has been launched after React Native, its community is increasing exponentially. Here are several latest statistics that define the popularity of both frameworks.

Currently, Flutter has got 133k stars on GitHub and 19.7k live projects forked by the community. Also, there are 989 Flutter contributors on GitHub for any professional help.

React Native has got 99.7k stars on GitHub and 21.5k live projects forked by the community. Besides this, there are 2,267 React Native contributors available on GitHub for support.

Testing

Testing is yet another factor that developers consider while choosing a cross-platform framework. Ensuring that your code runs smoothly with less time and effort is the main objective of any development.

Hence, the majority of frameworks offer the functionality of testing. With the help of this testing functionality, developers conduct unit, integration, and UI tests on apps periodically.

Flutter offers better testing of apps than React Native. It provides top-notch support to developers to conduct automatic testing of apps as it relies on Dart. It possesses various features to test apps at the unit, widget, and integration level.

React Native doesn’t offer any support for unit and integration level testing. Moreover, there are only some specific tools for unit-level testing of React Native apps. Hence, developers have to utilize various third-party tools available in the market, such as Appium, Detox, and Jest, for conducting different kinds of testing.

Flutter also offers detailed documentation on testing. Besides this, it also provides a unique feature using which developers can create widget tests to test the user interface and leverage unit testing.
