More Dart — Literally

A collection of extensively tested extensions that make Dart a better place:

Library	Description
async	Extensions to Stream.
cache	Caching strategies and their expiry policy.
char_matcher	Character classes, their composition, and operations on strings.
collection	Extensions to Iterable and new collection types.
comparator	Common comparators, and extensions to perform advanced operations.
diff	Tools for comparing lists.
feature	Information about the runtime environment.
functional	Types and features known from functional programming.
graph	Graph-theory objects and algorithms.
interval	Continuous interval data type over a comparable type.
math	Common mathematical functions.
number	Number types: fraction, complex, quaternion.
printer	Fluent interface to configure sophisticated formatter.
temporal	Extensions to DateTime and Duration types.
tuple	Tuple extension methods on generic records.

And there are more to come ...

This library is open source, stable and well tested. Development happens on GitHub. Feel free to report issues or create a pull-request there. General questions are best asked on StackOverflow.

The package is hosted on dart packages. Up-to-date class documentation is created with every release.

Contributing

The goal of the library is to provide a loose collection of carefully curated utilities that are not provided by the Dart standard library. All features must be well tested. New features must have significant advantages over alternatives, such as code reduction, readability improvement, speed increase, memory reduction, or improved accuracy. In case of doubt, consider filing a feature request before filing a pull request.

History

This library started in April 2013 as I was working through the puzzles of Project Euler and encountered some missing features in Dart. Over time the code grew and became more useful in many other places, so I created this reusable library.

Some parts of this library are inspired by similar APIs in Google Guava (Google core libraries for Java) and Apache Commons (a repository of reusable Java components).
