Flutter vs React Native 2022

In this article, we’ll look at the differences between Flutter vs React Native, explore what makes each one unique, and find out the reasons why they’re both popular.

The two most well-known mobile app development frameworks that cross-platform that are available currently is Flutter as well as React Native. These two giants are backed by the two biggest technology companies around the globe: Google and Facebook, respectively.

Flutter vs React Native

What is Flutter?

Flutter is an open-source cross-platform UI framework that was developed by Google. The first version was released in May 2017 Flutter has steadily grown in popularity throughout the years.

One of Flutter’s major advantages is its ability to allow you to build cross-platform apps by using a single source code. Traditionally, a business would require several tools and developers in order to build an application that would be accessible through mobile, web and desktop.

For example, you might need:

  • A web developer with a specialization in web development making use of React to create the website
  • Another developer is using C# and Java to develop the desktop version
  • A mobile-specific developer that uses Kotlin along with Swift to build Android and iOS applications.

This method would require the participation of a whole development team, and numerous meetings to ensure the branding and design are uniform for all platforms. Also, you must consider tests for every platform and address their specific issues and bugs.

With Flutter companies can engage one developer to build applications across platforms using a single source code base to handle. This greatly reduces the amount of time and money needed to create and maintain an app.

Flutter 3 introduced some major modifications. Although the API used to write web and mobile applications isn’t drastically changed but you now have the ability to use the same codebase to write iPhone, Android, Web, Windows, Mac, and Linux applications with Flutter Compiler. Flutter Compiler.

Furthermore, Flutter 3 provides greater assistance for Firebase and a casual Games Toolkit for making games using Flutter.

What is React Native?

React Native is a cross-platform framework developed through Facebook. With a base of code that is written using JavaScript, React Native makes it relatively easy to develop cross-platform apps, which lowers the barriers to entry in the field of JavaScript developers.

Development of web applications has been in existence for a long time and the majority of web developers have used JavaScript for the majority of their careers. Mobile development is still relatively new, however the technology has grown quite a bit in the last few years.

If you are already familiar with JavaScript then the learning curve for mobile application development with React Native won’t be as difficult.

Nowadays, a lot of businesses are making use of React Native for app development. Microsoft recently launched its brand new Xbox store app with React Native, for one instance. Similar to Flutter, React Native makes it possible to build applications that run across multiple platforms using a single codebase.

React Native v0.68 that was released as of the date at the time of writing, allows an opt-in option for using the newly released React Native architecture using the Fabric Renderer and TurboModule system. There are no libraries that have moved to this new architecture, and that’s why it’s an opt-in-only.

Fabric Renderer Fabric Renderer brings concurrency, React Suspense and rendering via servers in React Native, along with an enhanced and faster toolset.

What are the key distinctions that exist between Flutter as well as React Native?

Flutter as well as React Native share a lot of features, but they’re also very different in many crucial ways.

To begin, Flutter uses the Dart programming language within its codebase and React Native uses JSX.

Both languages are built on the C-style syntax, and adhere to object-oriented principles. Due to this commonality Flutter as well as React Native are very similar in design and the code is alike as well.


Flutter as well as React Native both have excellent documentation guides. These guides make it simple for programmers to get started creating applications.

The documentation of Flutter is simple to read because it’s well organized, well-organized and precise. Contrary to this, React Native’s documentation isn’t easy to read.

React Native also heavily depends on dependency libraries developed by the community The documentation for the library isn’t as well-organized.

Dynamic contrasts with. static programming

In terms of the programming language that is fundamental there is a distinct distinction in Flutter in comparison to React Native.

JavaScript is dynamic in its very nature. It allows you to alter the value of various data types, making it extremely flexible. Dart is both static and dynamic that allows it to be two distinct functions.

Statically-typed languages are generally thought to be more secure because it requires the user to declare and use the right data type. For instance, it is impossible to assign the string a number without producing an error.

You can ensure more security for your type and check for errors by using JavaScript when you decide to utilize TypeScript rather than TypeScript, which is a strict syntactical version of JavaScript.

The size of the project

React Native applications are built using an JavaScript runtime. While they generally feature a larger build size however, this is able to be reduced within React Native simply by activating Hermes or ProGuard.

On the other hand Flutter apps are known to have larger files. It is inevitable that Flutter apps use up more space because of their larger build size.


Flutter utilizes a widget style for the creation of the user interface. React Native makes use of JavaScript along with JSX.

Flutter widgets come pre-made and therefore you don’t have to design your own custom widgets unless wish to. Since the widgets were developed and checked by Google and Google, you don’t have to be concerned over compatibility concerns.

When you’re working with a language such as Swift to create mobile apps generally, you won’t be able to view the code Apple created to make UI components, such as buttons. In contrast, you’ll be able to look at the code of Flutter widgets and see the process by which Google developers came up with the widgets.

The two frameworks Flutter as well as React Native make use of CSS Flexbox to create layouts. The way that each framework implements the concept is different, however so long as you are familiar with Flexbox it shouldn’t be any issues creating the layout of your app.

The team who worked on Flutter also developed the tools for developers that are available on Google Chrome. Google Chrome browser, which will allow for a smooth switch since the tools for debugging are very identical.

What makes mobile app development so sought-after?

The mobile application development has been growing steadily in the last few years. The majority of the world is using a mobile phone which means that the number of people who use mobile apps is huge. Today there is apps for just about anything.

There are many options to consider in the event that you decide to build an app for mobile devices.

You could follow the native path that is, using Swift to build mobile applications or Kotlin to develop Android applications. These are the languages that both Apple and Google utilize, respectively and you should expect first-party support as well as frequent updates.

Alternately, you can choose to take the cross-platform route and utilize Flutter and React Native. In general, native developers will make use of Xcode along with Swift to develop iOS applications and Android Studio and Kotlin for Android applications. These tools are suitable to cross-platform work.

It’s also very normal for developers to utilize the integrated development platform (IDE) like Visual Studio Code.

Most developers typically make use of the IDE, Android Studio, or Xcode to build apps using Flutter or React Native. Personally, I would prefer utilize Visual Studio Code for React Native apps , and Android Studio for Flutter apps.

Flutter vs React Native : Demand

As of the time of posting, React Native is significantly higher in popularity than Flutter due in part due to React Native’s connection to the web-based framework that is popular React. React Native has also been for a longer time, which means its users are more numerous.

In this sense, there’s currently a greater demands of React Native developers than for Flutter developers. But, it doesn’t mean that Flutter isn’t popular; in reality, Flutter is continuing to increase in popularity with time.

Android Studio has a Flutter plugin, which includes code aids that make it much simpler to write and test your code. As of the time of posting, the plugin is available for around twelve million downloaded and this goes to demonstrate just how popular Flutter is.

Flutter vs React Native : Performance

It’s difficult to determine if the Flutter, or React Native app has better performance. There will be a difference for each app. There are numerous variables to consider including the kind of app, the codebase transitions, animations and animations, the app’s size layout, data passing and the phone of the end user, and much more.

The two Flutter as well as React Native are open source and are free to use. Both are well-maintained , as you’d expect since they’re both developed through Google along with Facebook.

It is possible to test applications made using both frameworks in virtual form, by using a built-in simulator for your PC for iOS and Android or, natively on your mobile.

If you are planning to create applications for iOS you must know that the SDK is available only on Apple computers, which means Windows users as well as Linux users are not able to develop apps. You can however create Android applications for development for any platform.

Both frameworks employ hot reloading. This makes development faster since you are able to instantly view the changes that were made.

There’s some debate regarding the extent to which Flutter as well as React Native are actually native. To be considered 100 % native, they have to use the same language that they were developed for, namely Swift to iOS along with Kotlin as well as Java to Android.

The experience you experience when you use an application written using React Native and Flutter is mostly it’s a native experience. It is however, React Native uses JavaScript bridges to connect with native language, which could make the app slower to run.

As a contrast Flutter’s code Dart code which Flutter makes compiles directly into C and is the same as one could hope for. Flutter code does not need any bridges in order to communicate to native codes. It is safe to assume that will result in better performance.

To resolve the performance issue To improve performance, React Native’s latest architecture has replaced JavaScript bridges by JavaScript Interface (JSI). JSI lets developers directly call native modules without the need for bridges.

The latest React Native architecture also allows developers to use lazy loading native modules using TurboModules that can help speed up the speed of startup.

Each of Flutter as well as React Native are continuing to enhance their performance through their community and developer assistance. However, as of right now Flutter is slightly ahead in performance.

Flutter vs React Native : Developer ecosystem

Flutter developers usually look up their the official document. But, React Native has several alternatives; one is you can use the Official documentation or a different platform that is most well-known, one being Expo.

Expo provides additional features and options for customization with an integrated library of icons, in contrast to those in the React Native docs are more simple.

React Native is a React Native ecosystem is more advanced and has more users since JavaScript has been in use since 1995. Flutter, however was first released in 2017.

React Native has a very active community on social media however, Flutter is a serious contender. As of this posting, Flutter has more stars than React Native on GitHub.

The numbers are pretty similar across all social media platforms as well. Flutter is more popular with followers on Twitter that React Native While the numbers are similar but there are far more active Flutter developers who are active on Reddit as compared to actively active React Native developers.

The two Flutter, as well as React Native, have been used in numerous commercial applications. Flutter was utilized to develop applications that are available for Baidu, Groupon, and eBay to mention just a few. The applications created for Facebook, Instagram, Shopify as well as Discord were developed using React Native.

Flutter vs React Native : Device compatibility

Flutter as well as React Native both support Android devices that have ARM processors as well as Apple devices that run from the iPhone 4s and up. Both are also compatible with Android as well as iOS simulators to develop apps.

Apple gadgets are required to have iOS 9 plus for Flutter applications as well as iOS 11 and higher to run React Native apps. Android phones require API levels 19 (Android 4.4) and higher for Flutter apps. API Level 23 (Android 6.0) for React Native apps.

A minimum version that is supported by Exposed-based React Native apps is Android 5 or iOS 10 and up.
