Contains utility functions and classes in the style of dart:collection to make
working with collections easier.
The package contains functions that operate on lists.
It contains ways to shuffle a List, do binary search on a sorted List, and
various sorting algorithms.
The package provides a way to specify the equality of elements and collections.
Collections in Dart have no inherent equality. Two sets are not equal, even if they contain exactly the same objects as elements.
The Equality interface provides a way to define such an equality. In this
case, for example, const SetEquality(IdentityEquality()) is an equality
that considers two sets equal exactly if they contain identical elements.
Equalities are provided for Iterables, Lists, Sets, and Maps, as well as
combinations of these, such as:
const MapEquality(IdentityEquality(), ListEquality());This equality considers maps equal if they have identical keys, and the
corresponding values are lists with equal (operator==) values.
Utilities for "zipping" a list of iterables into an iterable of lists.
An interface and implementation of a priority queue.
The package contains classes that "wrap" a collection.
A wrapper class contains an object of the same type, and it forwards all methods to the wrapped object.
Wrapper classes can be used in various ways, for example to restrict the type of an object to that of a supertype, or to change the behavior of selected functions on an existing object.
