Dart is an open-source, general-purpose programming language developed by Google. It is optimized for building fast, modern applications across multiple platforms, including web, mobile, and desktop. Dart is the language behind Flutter, Google’s UI toolkit for creating natively compiled applications for mobile, web, and desktop from a single codebase. It supports both object-oriented and functional programming paradigms, has a rich set of core libraries, strong typing, and asynchronous programming features using Future
and Stream
. Dart’s syntax is clean and familiar to developers coming from languages like Java, C#, or JavaScript, making it easy to learn and productive for large-scale application development.
Developer & Open-Source: Created by Google; fully open-source.
Platform Support: Runs on mobile, web, server, and desktop.
Primary Use: Flutter applications for cross-platform UI development.
Type System: Statically typed, supports type inference.
Object-Oriented: Supports classes, inheritance, mixins, and interfaces.
Functions as First-Class Citizens: Can be assigned to variables, passed as parameters.
Asynchronous Programming: Built-in support for async
, await
, Future
, and Stream
.
Null Safety: Helps avoid null reference errors at compile time.
Rich Standard Library: Includes collections, math, IO, async, and more.
Compilers: Can compile to native code for mobile/desktop and JavaScript for the web.
Hot Reload: When used with Flutter, allows rapid UI changes without restarting the app.
