Flutter vs Xamarin in Cross-platform app development: A Comparison Focused

For the last decade, mobile application development policies create a huge difference. According to a survey the mobile application industry has sustained tremendous germination, especially regarding application development and there were more than 2 billion smartphone users in this world, and by the end of 2022, the number is approximated to expand to over 5 billion.

There are three popular platforms, Android from Google, iOS from Apple and Windows Mobile developed by Microsoft. Sometimes mobile application developers dependent on platform-specific tools to develop native apps, which could only run on a single platform. But this is more pricey and time-consuming.

So, mobile application development companies are rushing to cross-platform mobile application development. And there in the cross-platform development, two development frameworks Flutter and Xamarin are two rivals. So, we are persisting to discuss which is the best Flutter or Xamarin.

Overview of Xamarin and Flutter Frameworks

Xamarin is a San Francisco-based software company, owned by Microsoft in May 2011. Xamarin prolongs the .NET developer platform with tools and libraries especially for constructing applications for Android, iOS, tvOS, watchOS, macOS, and Windows, a cross-platform implementation of the Common Language Infrastructure and Common Language Specifications.

Flutter is Google’s mobile UI framework which implements a fast and dramatic way for developers to create native applications for both Android and iOS. Nowadays developers favor developing an application interface with Flutter, a build from a single code base. And at that very same point, Flutter is excellent because, it composed directly from the native arm code, uses the GPU and can obtain platform APIs and services.

Flutter and Xamarin Comparison


  • Code: C#,Java,Kotlin/Swift for Native UI.
  • Complication (iOS and Android): AOT & JIT.
  • Probability: iOS, Android, Windows, macOS.
  • Code Reuse: Up to 96 % of code.
  • UI Engineering: Native and Code Sharing for the cost of a native experience.
  • 3rd Party Library Compatibility: Moderate.
  • Binary Size: Relatively Small.
  • App Size: Relatively Big.
  • Price: Open Source Visual Studio Commercial Use.
  • Community: Large.


  • Code: Dart.
  • Complication (iOS and Android): AOT + DartVM.
  • Probability: iOS, Android.
  • Code Reuse: Up to 70 % of code.
  • UI Engineering: Customization with built-in UI components.
  • 3rd Party Library Compatibility: High.
  • Binary Size: Relatively Big.
  • App Size: Relatively Big.
  • Price: Open Source.
  • Community: Growing.


Flutter is aimed at Android and

, while Xamarin recommends Android, iOS, and Windows Platforms as well as macOS apps. The more significant ecosystem provides Xamarin an advantage above Flutter.

The purpose is that Flutter applications aren’t compressed to Windows mobile platform isn’t a great weakness. But Xamarin can be a one-fit-for-all when you require to develop apps for Windows mobile.

Flutter is not cooperative with 32-bit OS devices. So, for instance, if you are proposing to cover older phones like iPhone 5, Xamarin would be a better alternative.

UI Design:

Although Xamarin’s effectiveness of native UI elements is a great thing, it begins with a cost, as platforms are updated repeatedly, and this may take extended for the framework to adapt to the new versions.

This also presents Xamarin only fitting for logic code partition but not excellent for UI code reuse. On top of that, we’d suggest using native modules to handle troublesome graphics such as games and animations.

Flutter employs built-in widgets and doesn’t utilize native UI segments. Widgets then are required to be further customized concerning the program you’re creating UI for.

Currently, Flutter recommends an assortment of layouts, foundation widgets, and programs to design graphics and support 2D APIs, gestures, impressions, animation, and other characteristics.

While Flutter UI comments are still in development, they have the potential to emerge into a convincing UI-building environment. Additionally, Flutter appears with Material Design and Cupertino elements.

Although developers usually maintain the Flutter initiative, it doesn’t fundamentally mean that Xamarin is delivered old-fashioned. It presents sense to reflect Flutter if you are new to cross-platform mobile development as this platform is expected to become hot quickly.

However, Xamarin is currently more sophisticated in many forms, including community, toolset, and durability. Generally, for aggregate and long-term projects we would suggest impaling to Xamarin, principally if you have a team of C# and .NET developers and you’re into the Microsoft ecosystem.
