The framework uses the Dart programming language (developed by Google). It ensures rapid application development for any mobile platform. Dart is a client-optimized object-oriented language. The Dart language is type-safe; it uses static type checking to ensure that a variable’s value always matches the variable’s static type. As a result, developers can write more safe code with less or without bugs.
In addition, Dart apps can be run directly on a server, but with the Dart2js transcompiler, they are converted to JS for the browser and to native code for the mobile devices. The structure of Dart is very similar to Java.
