Why did Google create Dart?

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. It is easy to learn, stable, and creates high-performance applications.

The idea was to create a dynamically typed language that developers could pick up pretty easily and that would increase developer productivity . Because of this, the team always focused not just on making the language accessible, but also on the other tools that developer need to be productive in a language.

The dart:io library is aimed at code that runs in Flutter and the standalone Dart VM .
