Dart was revealed for the first time in the GOTO conference in the month of 10th – 12th October 2011 at Aarhus, Denmark. It is initially designed by the Lars bark and Kespar and developed by Google.
The first version 1.0 of Dart was released on November 14th, 2013, intended as a replacement of JavaScript.
In July 2014, the first edition of Dart language was approved by Ecma International approved at its 107th General Assembly.
The first version was criticized due to a malfunction on the web and this plan was dropped in 2015 with the 1.9 release of Dart.
The second version of Dart 2.0 was released in August, including a sound type system.
The recent version Dart 2.7 is supplemented with the extension method, which enables us to add any type of functionality.
