General-purpose packages

以下包被广泛的应用于项目中。

The following packages are useful for a wide range of projects.

Package	Description	Commonly used APIs
archive	Encodes and decodes various archive and compression formats.	Archive, ArchiveFile, TarEncoder, TarDecoder, ZipEncoder, ZipDecoder
characters	String manipulation for user-perceived characters (Unicode grapheme clusters).	String.characters, Characters, CharacterRange
http	A set of high-level functions and classes that make it easy to consume HTTP resources.	delete(), get(), post(), read()
intl	Internationalization and localization facilities, with support for plurals and genders, date and number formatting and parsing, and bidirectional text.	Bidi, DateFormat, MicroMoney, TextDirection
json_serializable	An easy-to-use code generation package. For more information, see JSON Support.	@JsonSerializable
logging	A configurable mechanism for adding message logging to your application.	LoggerHandler, Level, LogRecord
mockito	A popular framework for mocking objects in tests. Especially useful if you are writing tests for dependency injection. Used with the test package.	Answering, Expectation, Verification
path	Common operations for manipulating different types of paths. For more information, see Unboxing Packages: path.	absolute(), basename(), extension(), join(), normalize(), relative(), split()
quiver	Utilities that make using core Dart libraries more convenient. Some of the libraries where Quiver provides additional support include async, cache, collection, core, iterables, patterns, and testing.	CountdownTimer (quiver.async); MapCache (quiver.cache); MultiMap, TreeSet (quiver.collection); EnumerateIterable (quiver.iterables); center(), compareIgnoreCase(), isWhiteSpace() (quiver.strings)
shelf	Web server middleware for Dart. Shelf makes it easy to create and compose web servers, and parts of web servers.	Cascade, Pipeline, Request, Response, Server
stack_trace	Methods for parsing, inspecting, and manipulating stack traces produced by the underlying Dart implementation. Also provides functions to produce string representations of stack traces in a more readable format than the native StackTrace implementation. For more information, see Unboxing Packages: stack_trace.	Trace.current(), Trace.format(), Trace.from()
test	A standard way of writing and running tests in Dart.	expect(), group(), test()
yaml	A parser for YAML.	loadYaml(), loadYamlStream()

在 Dart 核心库上的扩展包

Packages that expand on Dart core libraries

以下包基于核心库构建，添加功能，并补全缺少的功能：

Each of the following packages builds upon a core library, adding functionality and filling in missing features:

Package	Description	Commonly used APIs
async	Expands on dart:async, adding utility classes to work with asynchronous computations. For more information, see Unboxing Packages: async part 1, part 2, and part 3.	AsyncMemoizer, CancelableOperation, FutureGroup, LazyStream, Result, StreamCompleter, StreamGroup, StreamSplitter
collection	Expands on dart:collection, adding utility functions and classes to make working with collections easier. For more information, see Unboxing Packages: collection.	Equality, CanonicalizedMap, MapKeySet, MapValueSet, PriorityQueue, QueueList
convert	Expands on dart:convert, adding encoders and decoders for converting between different data representations. One of the data representations is percent encoding, also known as URL encoding.	HexDecoder, PercentDecoder
io	Contains two libraries, ansi and io, to simplify working with files, standard streams, and processes. Use the ansi library to customize terminal output. The io library has APIs for dealing with processes, stdin, and file duplication.	copyPath(), isExecutable(), ExitCode, ProcessManager, sharedStdIn
