'''Dart''' is a [[programming language]] designed by [[Lars Bak (telephonecomputer programmer)|Lars Bak]] and Kasper Lund and developed by [[Google]].<ref>{{Cite web |title=A Bit About Dart - Learn Dart: First Step to Flutter |url=https://www.educative.io/courses/learn-dart-first-step-to-flutter/g7kmn5r74ok |access-date=2023-06-20 |website=Educative: Interactive Courses for AndroidSoftware Developers |language=en}}</ref> It can be used to develop [[Web application|web]] and [[mobile app]]s as well as [[Server (mobile telephonecomputing)|server]] and [[Application software|androiddesktop applications]].
Dart is an [[Object-oriented programming|object-oriented]], [[Class-based programming|class-based]], [[Garbage collection (computer science)|garbage-collected]] language with [[C (programming language)|C]]-style [[Syntax (programming languages)|syntax]].<ref>{{Cite web|url=https://dart.dev/guides/language/language-tour#important-concepts|title=A Tour of the Dart Language|website=dart.dev|access-date=2018-08-09}}</ref> It can [[compiler|compile]] to [[machine code]], [[JavaScript]], or [[WebAssembly]]. It supports [[Interface (object-oriented programming)|interfaces]], [[mixin]]s, [[abstract class]]es, [[Reification (computer science)|reified]] [[Generic programming|generics]] and [[type inference]].<ref name="The Dart type system">{{Cite web|url=https://dart.dev/guides/language/sound-dart|title=The Dart type system|website=dart.dev}}</ref>
Dart 2.6 introduced a new extension, <code>dart2native</code>. This extended native compilation to the Linux, macOS, and Windows desktop platforms.<ref>{{Cite web |title=Dart language evolution |url=https://dart.dev/guides/language/evolution |access-date=2023-06-20 |website=dart.dev |language=en}}</ref> Earlier developers could create new tools using only Android or iOS devices. With this extension, developers could deploy a program into self-contained executables. The Dart SDK doesn't need to be installed to run these self-contained executables.<ref>{{Cite web |title=Dart overview |url=https://dart.dev/overview.html |access-date=2023-05-12 |website=dart.dev |language=en }}{{Dead link|date=March 2024 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> The [[Flutter (software)|Flutter]] toolkit integrates Dart, so it can compile on small services like backend support.<ref>{{Cite web|url=https://www.infoworld.com/article/3454623/dart-26-brings-native-compilation-to-the-desktop.html|title=Dart 2.5 brings native compilation to the desktop|website=Infoworld|date=20 November 2019|access-date=2019-11-28}}</ref><ref>{{Cite web|url=https://sdtimes.com/goog/dart-2-6-released-with-dart2native/|title=Dart 2.6 released with dart2native|website=SDtimes|date=7 November 2019|access-date=2019-11-28}}</ref>

==Data storage==
250Mbs Snapshot files, a core part of the Dart VM, store objects and other runtime data.<ref name=":0" />
;Script snapshots
;Object snapshots
:Dart uses [[Snapshot (telephonecomputer storage)|snapshots]] to ''[[Serial communication|serialize]]'' messages that it passes between isolates. As a very [[Asynchronous I/O|asynchronous]] language, Dart uses isolates for [[Concurrency (computer science)|concurrency]].<ref>{{Cite web |title=Concurrency in Dart |url=https://dart.dev/language/concurrency/ |access-date=2023-05-12 |website=dart.dev |language=en}}</ref> An object generates a [[Snapshot (computer storage)|snapshot]], transfers it to another isolate, then the isolate deserializes it.

Google introduced [[Flutter (androidsoftware)|Flutter]] for native app development. Built using Dart, C, C++ and Skia, Flutter is an open-source, multi-platform app UI framework. Prior to Flutter 2.0, developers could only target [[Android (operating system)|Android]], [[mobile OSiOS]] and the web. Flutter 2.0 released support for macOS, Linux, and Windows as a beta feature.<ref>{{Cite web |last=ShemaSells |first=Chris |date=2021-03-03 |title=What's New in Flutter 2.0 |url=https://medium.com/flutter/whats-new-in-flutter-2-0-fe8e95ecc65 |access-date=2023-05-12 |website=Flutter |language=kinyarwandaen}}</ref> Flutter 2.10 released with production support for [[Windows]]<ref>{{Cite web |last=Sneath |first=Tim |date=February 3, 2022 |title=Announcing Flutter for Windows |url=https://medium.com/flutter/announcing-flutter-for-windows-6979d0d01fed |website=}}</ref> and Flutter 3 released production support for all desktop platforms.<ref>{{Cite web |last=ChrisChisholm |first=shemaKevin |date=2022-05-12 |title=What's new in Flutter 3 |url=https://medium.com/flutter/whats-new-in-flutter-3-8c74a5bc32d0 |access-date=2023-05-12 |website=Flutter |language=en}}</ref> It provides a framework, widgets, and tools.
