- *
- * Built-in types, collections,
- * and other core functionality for every Dart program.
- *
- * This library is automatically imported.
- *
- * Some classes in this library,
- * such as [String] and [num],
- * support Dart's built-in data types.
- * Other classes, such as [List] and [Map], provide data structures
- * for managing collections of objects.
- * And still other classes represent commonly used types of data
- * such as URIs, dates and times, and errors.
- *
- * ## Numbers and booleans
- *
- * [int] and [double] provide support for Dart's built-in numerical data types:
- * integers and double-precision floating point numbers, respectively.
- * An object of type [bool] is either true or false.
- * Variables of these types can be constructed from literals:
- *
- *     int meaningOfLife = 42;
- *     double valueOfPi  = 3.141592;
- *     bool visible      = true;
- *
- * ## Strings and regular expressions
- *
- * A [String] is immutable and represents a sequence of characters.
- *
- *     String shakespeareQuote = "All the world's a stage, ...";
- *
- * [StringBuffer] provides a way to construct strings efficiently.
- *
- *     StringBuffer moreShakespeare = new StringBuffer();
- *     moreShakespeare.write('And all the men and women ');
- *     moreShakespeare.write('merely players; ...');
- *
- * The String and StringBuffer classes implement string concatenation,
- * interpolation, and other string manipulation features.
- *
- *     String philosophy = 'Live on ';
- *     String get palindrome => philosophy + philosophy.split('').reversed.join();
- *
- * [RegExp] implements Dart regular expressions,
- * which provide a grammar for matching patterns within text.
- * For example, here's a regular expression that matches
- * a string of one or more digits:
- *
- *     var numbers = new RegExp(r'\d+');
- *
- * Dart regular expressions have the same syntax and semantics as
- * JavaScript regular expressions. See
- * <http://ecma-international.org/ecma-262/5.1/#sec-15.10>
- * for the specification of JavaScript regular expressions.
- *
- * ## Collections
- *
- * The dart:core library provides basic collections,
- * such as [List], [Map], and [Set].
- *
- * A List is an ordered collection of objects, with a length.
- * Lists are sometimes called arrays.
- * Use a List when you need to access objects by index.
- *
- *     List superheroes = [ 'Batman', 'Superman', 'Harry Potter' ];
- *
- * A Set is an unordered collection of unique objects.
- * You cannot get an item by index (position).
- * Adding a duplicate item has no effect.
- *
- *     Set villains = new Set();
- *     villains.add('Joker');
- *     villains.addAll( ['Lex Luther', 'Voldemort'] );
- *
- * A Map is an unordered collection of key-value pairs.
- * Maps are sometimes called associative arrays because
- * maps associate a key to some value for easy retrieval.
- * Keys are unique.
- * Use a Map when you need to access objects
- * by a unique identifier.
- *
- *     Map sidekicks = { 'Batman': 'Robin',
- *                       'Superman': 'Lois Lane',
- *                       'Harry Potter': 'Ron and Hermione' };
- *
- * In addition to these classes,
- * dart:core contains [Iterable],
- * an interface that defines functionality
- * common in collections of objects.
- * Examples include the ability
- * to run a function on each element in the collection,
- * to apply a test to each element,
- * to retrieve an object, and to determine length.
- *
- * Iterable is implemented by List and Set,
- * and used by Map for its keys and values.
- *
- * For other kinds of collections, check out the
- * [dart:collection](#dart-collection) library.
- *
- * ## Date and time
- *
- * Use [DateTime] to represent a point in time
- * and [Duration] to represent a span of time.
- *
- * You can create DateTime objects with constructors
- * or by parsing a correctly formatted string.
- *
- *     DateTime now = new DateTime.now();
- *     DateTime berlinWallFell = new DateTime(1989, 11, 9);
- *     DateTime moonLanding = DateTime.parse("1969-07-20");
- *
- * Create a Duration object specifying the individual time units.
- *
- *     Duration timeRemaining = new Duration(hours:56, minutes:14);
- *
- * In addition to DateTime and Duration,
- * dart:core contains the [Stopwatch] class for measuring elapsed time.
- *
- * ## Uri
- *
- * A [Uri] object represents a uniform resource identifier,
- * which identifies a resource on the web.
- *
- *     Uri dartlang = Uri.parse('http://dartlang.org/');
- *
- * ## Errors
- *
- * The [Error] class represents the occurrence of an error
- * during runtime.
- * Subclasses of this class represent specific kinds of errors.
- *
- * ## Other documentation
- *
- * For more information about how to use the built-in types, refer to [Built-in
- * Types](http://www.dartlang.org/docs/dart-up-and-running/contents/ch02.html#built-in-types)
- * in Chapter 2 of
- * [Dart: Up and Running](http://www.dartlang.org/docs/dart-up-and-running/).
- *
- * Also, see [dart:core - Numbers, Collections, Strings, and
- * More](https://www.dartlang.org/docs/dart-up-and-running/ch03.html#dartcore---numbers-collections-strings-and-more)
- * for more coverage of classes in this package.

- * The
- * [Dart Language Specification](http://www.dartlang.org/docs/spec/)
