Parameters | Flutter | Xamarin |
---|
Definition | Flutter is an open-source, cross-platform UI toolkit to create fast, beautiful, natively compiled applications for mobile, web, and desktop. It builds the app with one programing language and a single codebase. | Xamarin is an open-source, cross-platform mobile development app for iOS, Android, and Windows. It allows the developer to write the code once and reused it everywhere. |
Backed By | It is backed by Google Inc. | It is backed by Microsoft (from 2016). |
Initial Release | May 2017 | December 2012 |
Language | It uses Dart programming that was introduced by Google in 2011 to build mobile apps. | It uses C# and XMAL programming language for creating applications. This language is primarily used for web development. |
Installation | We can use the Flutter framework by downloading the binary for a particular platform from GitHub. If we use the MacOS platform, it is required to download the flutter.zip file and add it as a PATH variable. | We can create a Xamarin app by using Visual Studio IDE for installation and Xamarin SDK. |
App Size | Flutter app is bigger because it uses app binaries that are usually larger in size. | Its binary size is relatively small, so the app is also in a smaller size. |
Performance | Its performance is amazing because it uses the Dart engine and hot reload feature. | Its performance is slow because it has a profiler that reported performance issues. |
Testing Support | It has a wide variety of testing features along with a unique widget testing feature. It also supports testing at the unit and integration level. | It supports various types of testing in Visual Studio, like Unit tests and UI tests. It also tests the app using third-party testing through frameworks, like Appium, XCUITest, or Expresso. It also has its own cloud testing environment. |
Technical Architecture | Flutter uses Dart Language, and here everything comes in the Dart engine, such as Material Design, Cupertino that provides all the necessary technologies to develop mobile apps. It also uses the Skia C++ engine that follows all the protocols, compositions, and channels. | It uses the Mono execution environment for developing a cross-platform app. This execution environment runs along with Objective-C runtime and Unix kernel when we work on iOS. If we work on Android, it runs with Android Runtime. |
Documentation | It has well organized and more informative documentation where we can get everything that we want in one place. | It has a rich set of documentation and development API to the developers. In comparison to Flutter, it supports more platforms. |
Community Support | Flutter is a new technology, so it does not have strong community support. However, it is advertised by Google; therefore, it would be very popular in the coming year. | It has huge community support and a vast marketplace because C# is backed by Microsoft. |
