Flutter is a UI toolkit used to develop applications for both mobile and desktop using a single programming language and code base. Flutter is an open source framework developed by Google to create high quality, high performance mobile applications across mobile operating systems – Android and iOS. It provides a simple, powerful, efficient and easy to understand SDK to write mobile applications in Googles own language, Dart.

With Flutter, we can write the app’s code once and deploy it on multiple platforms(Android, IOS, Desktop). Due to its flexibility and performance capabilities, Flutter is the top pick for modern app development across various platforms. Flutter, developed by Google, has undergone significant evolution since its launch in 2015 as “Sky”. Well, the first stable release of Flutter 1.0 was in 2018 as a goal to create a cross-platform UI toolkit. Significant updates followed Flutter 2.0’s release in 2021. With each release, Flutter enhanced its features, performance and ecosystem. In general, developing a mobile application is a complex and challenging task. There are many frameworks available to develop a mobile application. Android provides a native framework based on Java language and iOS provides a native framework based on Objective-C / Swift language.

Flutter framework offers the following features to developers −

• Modern and reactive framework.
• Uses Dart programming language and it is very easy to learn.
• Fast development.
• Beautiful and fluid user interfaces.
• Huge widget catalog.
• Runs same UI for multiple platforms.
