Dart 2, released early this year, had brought a new compiler support for generating code for mobile devices, a reworked web platform tools, and a sound type system (also known as type safe system) to support teams building complex apps.
The sound type system helps users during the development, informing when a developer violates a contract specified by the types. Now on Dart 2.1, both edit-time and compile time type checks are completed.
Dart 2.1 has improved the support for mixins. Mixins are a feature that enable developers to reuse a class’s code in multiple class hierarchies. A new syntax for mixins has been added, the keyword mixin can be used to define classes that can only be used as mixins.
