What is the difference between Xamarin and Flutter?

Xamarin and Flutter differ in programming language, approach, and target platforms. Xamarin, from Microsoft, uses C# and .NET. With this, developers can write code once and run it on iOS, Android, and Windows, while retaining access to native features through native APIs. Xamarin works very well within Visual Studio, making it great for developers used to Microsoft tools. Flutter, made by Google, uses Dart as its language and mainly targets iOS and Android. Flutter builds everything using “widgets,” making its UI look the same everywhere and giving developers powerful design options. It also offers fast updates with its hot reload feature. While Xamarin wraps native elements for a true native feel, Flutter builds its user interface from the ground up for each platform, providing flexibility but relying on its own system for UI.
