Dart is a programming language designed by Lars Bak and Kasper Lund and developed by Google.

[24] Accepted proposals for the specification and drafts of potential features can be found in the Dart language repository on GitHub.

[30] Dart ships with a complete standard library allowing users to write fully working system apps like custom web servers.

Dart can compile to native machine code for macOS, Windows, and Linux as command line tools.

Dart can compile apps with user interfaces to the web, iOS, Android, macOS, Windows, and Linux using the Flutter framework.

To achieve concurrency, Dart uses isolated, independent workers that do not share memory, but use message passing,[46] similarly to Erlang processes (also see actor model).

Null safety prevents the developer from introducing null-pointer exceptions, a common, but difficult to debug, error.

Snapshot files, a core part of the Dart VM, store objects and other runtime data.

[46] On November 18, 2011, Google released Dart Editor, an open-source program based on Eclipse components, for macOS, Windows, and Linux-based operating systems.

[50] The editor supports syntax highlighting, code completion, JavaScript compiling, running web and server Dart applications, and debugging.

[51] On April 18, 2015, Google retired the Dart Editor in favor of the JetBrains integrated development environment (IDE).

[52] Android Studio, IntelliJ IDEA, PyCharm, PhpStorm and WebStorm support a Dart plugin.

[53] This plugin supports many features such as syntax highlighting, code completion, analysis, refactoring, debugging, and more.

[59] In 2013, the Chromium team began work on an open source, Chrome App-based development environment with a reusable library of GUI widgets, codenamed Spark.

Built using Dart, C, C++ and Skia, Flutter is an open-source, multi-platform app UI framework.

[80] In 2004, Gilad Bracha (who was a member of the Dart team) and David Ungar first proposed Mirror API for performing controlled and secure reflection in a paper.
