Flutter Vs React Native Vs Xamarin – Which is Better for Cross-Platform App Development?


Cross-platform mobile app development frameworks enable the streamlined functioning of the same code across multiple platforms. This also aids in the easier development of mobile applications for various platforms such as Android or iOS using a single technological stack. A single technological stack enables you to write the code once and subsequently release it on multiple platforms at a time, and you wouldn’t have to waste your time developing individual versions of code for various platforms. Furthermore, you can also maintain a similar experience, appearance, and aesthetic on all the platforms using a single common codebase. By employing this development approach, one can decrease development costs and time in half while also freeing up resources for different teams’ needs.

However, when the question arises on choosing the best platform for Cross-Platform App Development, it can be quite perplexing, and there is fierce competition between Flutter VS React Native vs Xamarin. Let us look further into the cross-platform mobile application development comparison between Flutter vs Xamarin vs React Native.

Why Choose Cross-Platform Mobile Development?

There are a plethora of reasons why crossplatform mobile app development is seen in a bad light. This can be blamed on the lack of adequate technologies until recently, which brought a negative remark. They constrained developers’ options and significantly impacted performance metrics to the point where the costs of cross-platform development were no more justified. Albeit such disadvantages, several continue to choose Cross-Platform Mobile Development over Native development still, and some of these compelling reasons are:

  1. Decreased Development Process: The developmental process has been shortened, and thus, cross-platform development allows the users to share p to 96% of the codes across multiple platforms. Consequently, this leads to a considerably quicker development cycle: rather than designing two different programs, you need to create one, then transfer that code across operating systems, adding platform-specific modifications as needed.
  2. Small Team: You wouldn’t have to go through the trouble of hiring separate teams with Android or iOS-specific expertise. Cross-platform development would require few developers and hence, a small team. 
  3. Cost-Efficient: Cross-platform application development is unquestionably less expensive since you pay for a smaller team who work fewer hours and, thus, less labour which in general is cost-effective. 
  4. Streamlined Testing Process: A smaller codebase necessitates less testing, allowing Software developers to devote more time to each program component, leading to a better testing process.

Cross-Platform Mobile Development Comparison

Let us now look at the attributes of the individual platforms and compare them. 

Flutter Vs React Native Vs Xamarin: Popularity

About 1.6 million Xamarin developers work in 120 countries worldwide, making it a popular cross-platform framework.  React Native Framework is in a better situation, as evidenced by its consistent escalation in the user base over the past few years regarding the topic of popularity. On the other hand, the platform of Flutter is user-friendly and is one of the most popular frameworks, with 75.4 percent of users using it, while React Native is used by 62.5 percent of users worldwide. 

Flutter Vs React Native Vs Xamarin: Language Stack

Flutter: Flutter, which leverages Dart for mobile application frameworks for iOS and mobile application frameworks for Android, is the way to go if you want to build high-quality apps. Dart is a Programming language founded on C/C++ and Java and includes a multitude of features. Developers utilize Flutter to create a variety of apps owing to Dart.

React Native: React Native uses the popular, dynamic and high-performance language, i.e., javascript. React Native is a Facebook-sponsored project that blends the advantages of React JS and JavaScript. 

Xamarin: In the case of Xamarin vs React Native, Xamarin mixes the finest of C# and.Net to create Android, iOS, and Mac apps. A developer can use C# and Xamarin to develop functionality that would otherwise require native languages. Furthermore, the developers cannot use the native open-source libraries for Android, iOS, or Xamarin. To achieve such criterion, the developers may employ a variety of .Net libraries and then fill those gaps.

Flutter Vs React Native Vs Xamarin: Performance

Flutter Vs React Native Vs Xamarin - Performance

Flutter: Flutter has outstanding performance just because the Dart code of Flutter is arranged above the C library, progressing it like Native code. It has the effect of flattering the speed with which information is exchanged and shows a high-level performance.

React Native: React Native has a high-performing Native mobile development framework since it enables the easy meeting of design expectations. Since they rely on the Javascript bridge, React Native-based apps have a hard time rendering huge datasets. As a result, while using third-party frameworks to expedite your application is a viable alternative, it isn’t enough to beat Flutter in a close contest. React Native’s performance is similar to that of the native mobile applications, and thus, making it quite a popular choice for creating high-performance applications that native appearance. 

Xamarin: Xamarin, like React Native, provides a Native mobile development framework that is powerful and efficient. Furthermore, Xamarin can leverage all indigenous and newest APIs to take advantage of the hidden potential in Xamarin apps like ARKit for iOS and Android-Multi Windows.

Flutter Vs React Native Vs Xamarin: Architecture

Flutter: Flutter architecture supports Reactive UI, and it comes with a Dart application framework with the unidirectional data flow. The programmers may become frustrated due to the big size of the Flutter app. Even if the app’s size is reduced, it is still larger when compared with the other platforms. 

React Native: Web apps built using flux are known as client-side web applications since they are built on top of the React Native framework. The frameworks of almost all applications use the Model View control framework or the MVC. Developers may alter an existing program thanks to the module’s straightforward nature.

Xamarin: The Xamarin architecture includes a visual designing platform for creating native apps. The MVC and MVVM or the Model–View–ViewModel architecture used by Xamarin speeds up the application development process by reducing the diameter.

Flutter Vs React Native Vs Xamarin: User Interface

Flutter Vs React Native Vs Xamarin - User Interface

Flutter: Flutter is well-known for offering the best user interface compared to other platforms. When it comes to Flutter vs, React Native, both Flutter and React Native offer incredible productivity and effectiveness. 

React Native: React Native modules work in conjunction with native User interface controllers to provide a good user experience that is equivalent to that of native applications. React Native also uses ReactJS frameworks and UI elements, making UI development easier.

Xamarin: Xamarin.Forms or Xamarin.Android/iOS can be used to create the user interface. The latter method takes a long time but provides a user experience that is comparable to that of native applications. The project development becomes simpler and takes less time if you utilize Xamarin.Forms. However, this progress does not ensure that the app will have the same look and feel as native apps.

Flutter Vs React Native Vs Xamarin: Community Support

Flutter: Flutter is well-known for its active community. On the platform of GitHub, the framework has 82.4k stars (almost as many as React Native) and 502 contributors. They focus on many aspects of Flutter to deliver the greatest development possible experiences. Needless to say, the designers and the developers for Flutter are also active on QA forums and websites.

React Native: React Native was developed due to the developer industry’s desire for a mobile alternate option that would combine great Mobile app development services with a robust and flexible React Native App Development environment.

The React Native community is massive and active. GitHub boasts 90.5k stars and has 3,000+ developers working on improving React Native. This framework has a vast developer community throughout the world that can help answer questions on any website and forums. 

Xamarin: Since the platform of Xamarin is generally not free for the users, and they must acquire this cross-app platform, Xamarin has the smallest community support feature of the top three Cross-platform mobile development platforms. It appears that the community isn’t all that interested in helping. Moreover, on the internet, the Xamarin users do not have immediate access to help or assistance, and thus, it can be indicated that the number of repositories, users, and developers are far less than the React Native community.

Flutter Vs React Native Vs Xamarin: Code Reusability

Flutter: Developers can rewrite code parts that need to be modified to fit the platform while using Flutter. This improves the effectiveness and suitability of code reuse, and Flutter becomes particularly conducive to code reuse, enabling it a speedier and more efficient paradigm. Furthermore, code exchange is limited to iOS and Android in Flutter. 

React Native: In React Native, the developers can create the code for one time and transfer it anywhere and to multiple platforms. Unfortunately, that implies they must constantly determine what platform they are using and install a different element or feature set based on the platform they choose. Only a few major components can be shared between platforms; the remaining must be built from scratch for every forum.

Xamarin: By leveraging the language, Xamarin allows the developers to reuse up to 96% of existing C# code. Additionally, Xamarin also includes form elements, making it superior for reusable components than React Native and Flutter platforms, which share 60–90% of their code.
