Flutter is an open-source UI software development kit created by Google. It is used to develop cross platform applications from a single codebase for any web browser, Fuchsia, Android, iOS, Linux, macOS, and Windows. First described in 2015, Flutter was released in May 2017.

Flutter is known for its fast performance, expressive and flexible design, and hot reload capabilities. It is a popular choice for developing mobile apps, but it can also be used to create web apps, desktop apps, and even embedded apps.

Here are some of the benefits of using Flutter:

• Fast performance: Flutter apps are compiled to native code, which means they run as fast as native apps. This is important for apps that require a lot of processing power, such as games or video streaming apps.
• Expressive and flexible design: Flutter's widgets are highly customizable, so you can create beautiful and engaging user interfaces. Flutter also supports a wide range of input methods, so your app can be used on a variety of devices.
• Hot reload: Hot reload is a feature that allows you to make changes to your code and see the results instantly, without having to restart your app. This makes it much faster to iterate on your app's design and code.

If you are looking for a powerful and versatile UI toolkit, Flutter is a great option. It is easy to learn and use, and it can be used to create apps for a wide range of platforms.

Here are some examples of popular apps that are built with Flutter:
