Flutter is an open-source cross-platform UI toolkit developed by Google that allows developers to write code once and deploy to both Android and iOS. It uses Skia graphics library to provide high performance drawing across platforms. Flutter includes widgets and APIs to build native-like mobile, desktop and web apps using the Dart programming language. Many companies including Google and Alibaba are using Flutter to build applications.

26. Flutter vs
Xamarin / React
Native /
NativeScript /
Ionic / Cordova
...
State / Render architecture like
React Native
Fast Reload during
development
(Will) Target more than just
Mobile Platforms (Like
Xamarin)
Plugin hell like others (takes
time to plug and support all)
Not dependent on Native
Components (+/-)
Custom Made Widgets that
look like the native
Live Update/Code Push/
currently not available
