Is Flutter based on Dart?

Like React Native, Flutter uses reactive-style views . However, while RN transpiles to native widgets, Flutter compiles all the way to native code. Flutter controls each pixel on the screen, which avoids performance problems caused by the need for a JavaScript bridge.

Flutter doesn’t rely on native system components . Rather, Flutter has its own set of custom widgets, rendered and managed by the framework’s graphics engine (source). Users will see different UI components from typical native apps, but that isn’t necessarily a disadvantage.

Flutter is an Open-Source UI SDK developed by Google. It allows the development of iOS/Android apps and uses Dart as the programming language . Dart is an Open-Source, client-side programming language.
