    There is no denying that the usage of mobile phones has resulted in the increasing development of mobile applications. As a result, many organizations strive to create cross-platform robust mobile applications. Mobile applications come in handy for accomplishing a variety of tasks, such as online shopping, transferring money, ordering food, booking a cab, and the list goes on.

    With the increasing popularity of mobile applications, developers have created various frameworks to facilitate the creation of mobile applications. Among all, Flutter and Xamarin are the leading frameworks for building cross-platform mobile applications.

    If you are perplexed in choosing between Flutter and Xamarin for mobile application development, this article is for you.

    Through this article, we shall make you acquainted with the major differences between Flutter and Xamarin. Also, we shall discuss the features, benefits, and drawbacks of Flutter and Xamarin to have a better understanding.

    So, let us begin our discussion!

    What is Flutter?

    Flutter is an open-source framework for developing mobile applications that can work on any platform and devices of any screen size using a single codebase. We can also refer to Flutter as a UI toolkit that lets developers build applications for Android, iOS, Google Fuchsia , Windows, macOS, Linux, and web, from a single codebase.

    This means that there is no need to write the source code separately for different platforms, which significantly saves time and effort. Besides mobile app development, you can also create desktop, web, and embedded applications using Flutter.

    Moreover, this framework comprises two parts, namely a software development kit (SKD) and a framework. SDK is a collection of tools that assists you in developing applications. More precisely, it includes tools that convert the source code into the native machine code. A framework, on the flip side, is a collection of reusable components to create your applications.

    Since Google has developed the Flutter framework, it uses the Dart programming language , which is developed by Google for the development of web and mobile applications.


    In the 2015 Dart Developer Summit, Google unveiled the first version of Flutter as ‘Sky’. This version was capable of running only the Android platform. Later, in September 2018, at Google Developer Days, the company announced the last major release of Flutter, i.e., Flutter Release Preview 2, before Flutter 1.0. At the Flutter Live event in December 2018, the company released Flutter 1.0.

    In just a year, Google released Flutter 1.12 at the Flutter Interactive Event. Along with the release of Dart SDK version 2.8 in May 2020, the company released Fluter 1.17.0, which added support for the Meta API and improved the performance on iOS devices.

    Within a year, during an online Flutter Engage event, Google released Flutter 2, which was the major update to Flutter. This version added support for web-based applications with a CanvasKit renderer and desktop applications for Windows, macOS, and Linux platforms. In addition, Flutter 2 leveraged Dart 2.0.

    Further, in 2021, Google released Dart 2.14 and Flutter 2.5. This version supported Google’s Material Design and enhanced the Android’s full-screen mode. As of now, the current version of Flutter is 3.0.1, and that of Dart is 2.17.1.


    The following are some well-known features of Flutter:

    • Hot Reload: When you make changes to your source code, the hot reloading feature lets you immediately see how it appears in real-time on the test device. This enables developers to perfect each and every part of their applications and fix bugs quickly.
    • Cross-Platform Development: With Flutter, you just need to write one codebase and use it to create an application for various platforms and devices of any screen size.
    • Widget Library: This framework comes with rich widgets for creating an expressive UI. It allows developers to create custom and complex widgets that they can customize according to an application’s needs. In addition, Flutter also uses Material Design and the Cupertino pack, both consisting of a set of widgets that developers can use in their applications and provide an excellent user experience.
    • Pub: Pub is a package manager for Dart that contains reusable libraries and packages for Flutter and other Dart programs.
    • Support for Google’s Firebase: Since Flutter supports Google Firebase , developers use it for back-end development and to create scalable applications.


    The following are the remarkable benefits of using Flutter:

    • It is an open-source framework, and anyone can use it free of cost.
    • There is no need to test the two same apps on different platforms. Just testing a single codebase and the hot reloading feature is enough to detect bugs in your application.
    • Developers can create a feature-rich application for Android and iOS platforms with the help of hot reloading and a single codebase feature.
    • With Flutter, you can create expressive and appealing user interfaces with the help of the widgets of Material Design, Cupertino, and customized widgets.
    • It is very simple and easy to download and install flutter.


    Some significant downsides of using Flutter are as follows:

    • You need to learn a new programming language called Dart since Flutter uses this language for application development.
    • The applications you develop in Flutter are usually heavy.
    • Flutter does not support the creation of web applications.
    • You will have limited access to SDK libraries. Consequently, you do not get too many functionalities to build mobile applications.

    What is Xamarin?

    Xamarin is an open-source framework for creating modern mobile applications using the C# language and .NET framework. With this framework, developers can write native Android, iOS, and Windows applications and native user interfaces. Like Flutter, Xamarin also enables developers to write the codebase only once and use it for different platforms.

    If you have a basic understanding of .NET and experience working with Visual Studio, it is pretty easy to build applications in Xamarin. You do not need to learn any new programming language, like Flutter uses Dart, while working with Xamarin.


    In 2011, the developers of Mono, which is an open-source .NET framework, created Xamarin. After a year, Xamarin released Xamarin.Mac, a plugin for an existing MonoDevelop IDE. This IDE enabled developers to build C#-based applications for the macOS platform.

    Later, the year 2013 witnessed the release of Xamarin 2.0, which included two major components: Xamarin Studio and the integration with Visual Studio. In 2016, Microsoft announced the acquisition of Xamarin. After the acquisition, the company made Xamarin SDK open-source and integrated Xamarin with Visual Studio, an open-source IDE for building applications for Windows, Android, and iOS.


    The salient features of Xamarin are as follows:

    • Native Multi-Platform Support: Xamarin enables developers to create applications that are native to Android, iOS, and Windows. They can access all the tools and APIs for creating applications for these three platforms.
    • Single Codebase: Like Flutter, Xamarin also lets developers create applications for different platforms with a single codebase with just minimal changes.
    • Library Support: With Xamarin, you can use a wide variety of C++, Objective-C, Java, and C libraries. Using libraries results in reduced development time.
    • Modern Language Constructs: Xamarin leverages C# , a modern programming language including major improvements over Java and Objective-C. These improvements include sophisticated generics, functional constructs, dynamic language features, and many more.
    • Basic Class Library (BCL): Xamarin uses .NET BCL, a huge collection of classes that enable serialization, networking support, etc.


    The following are some noteworthy advantages of using Xamarin:

    • It is an open-source framework, and hence, you can use it freely.
    • Applications developed in Xamarin provide native-like high performance.
    • The single codebase or shared codebase feature enables developers to save a lot of time and effort.
    • It comes with testing tools to test applications. The Test Cloud function allows you to test your applications across more than 2,000 devices.


    Here are the significant downsides of using Xamarin:

    • When there is an introduction of any new feature in Xamarin, it takes time to reflect, which can create an obstacle in the development process.
    • Applications developed in Xamarin are relatively larger than native applications.
    • It is not ideal when your application requirement is heavy graphics or complex animations.
    • The community of Xamarin is comparatively smaller than iOS and Android communities.
    • The code you develop in Xamarin work only with the .NET stack and not with any other development stack.
