Welcome to the Dart API reference documentation, covering the Dart core libraries. These include:
- dart:core: Core functionality such as strings, numbers, collections, errors, dates, and URIs.
- dart:io: I/O for non-web apps.
- dart:html: DOM manipulation for web apps (available only to web apps).
For most of the core libraries - except for
dart:core - need to imported
before they're available for use. For example:
Additionally, you can find Dart packages at pub.dev.
The main site for learning and using Dart is dart.dev. Check out these pages:
- Support for asynchronous programming, with classes such as Future and Stream.
- Classes and utilities that supplement the collection support in dart:core.
- Encoders and decoders for converting between different data representations, including JSON and UTF-8.
- Built-in types, collections, and other core functionality for every Dart program.
- Interact with developer tools such as the debugger and inspector.
- Mathematical constants and functions, plus a random number generator.
- Lists that efficiently handle fixed sized data (for example, unsigned 8 byte integers) and SIMD numeric types.
- Utilities for building CLI apps.
- Foreign Function Interface for interoperability with the C programming language.
- File, socket, HTTP, and other I/O support for non-web applications.
- Concurrent programming using isolates: independent workers that are similar to threads but don't share memory, communicating only via messages.
- Basic reflection in Dart, with support for introspection and dynamic invocation.
- HTML elements and other resources for web-based applications that need to interact with the browser and the DOM (Document Object Model).
- A client-side key-value store with support for indexes.
- Utility methods to manipulate
- Scalable Vector Graphics: Two-dimensional vector graphics with support for events and animation.
- High-fidelity audio programming in the browser.
- 3D programming in the browser.
