# IterableBase<E> class Null safety

Base class for implementing Iterable.

This class implements all methods of Iterable, except Iterable.iterator, in terms of `iterator`.

## Properties

first → E
  Returns the first element. [...]
  read-only, inherited
hashCode → int
  The hash code for this object. [...]
  read-only, inherited
isEmpty → bool
  Returns `true` if there are no elements in this collection. [...]
  read-only, inherited
isNotEmpty → bool
  Returns true if there is at least one element in this collection. [...]
  read-only, inherited
iterator → Iterator<E>
  Returns a new `Iterator` that allows iterating the elements of this `Iterable`. [...]
  read-only, inherited
last → E
  Returns the last element. [...]
  read-only, inherited
length → int
  Returns the number of elements in this. [...]
  read-only, inherited
runtimeType → Type
  A representation of the runtime type of the object.
  read-only, inherited
single → E
  Checks that this iterable has only one element, and returns that element. [...]
  read-only, inherited

## Methods

any(bool test(E element)) → bool
  Checks whether any element of this iterable satisfies `test`. [...]
  inherited
cast<R>() → Iterable<R>
  Provides a view of this iterable as an iterable of `R` instances. [...]
  inherited
contains(Object? element) → bool
  Returns true if the collection contains an element equal to `element`. [...]
  inherited
elementAt(int index) → E
  Returns the `index`th element. [...]
  inherited
every(bool test(E element)) → bool
  Checks whether every element of this iterable satisfies `test`. [...]
  inherited
expand<T>(Iterable<T> f(E element)) → Iterable<T>
  Expands each element of this Iterable into zero or more elements. [...]
  inherited
firstWhere(bool test(E element), {E orElse()}) → E
  Returns the first element that satisfies the given predicate `test`. [...]
  inherited
fold<T>(T initialValue, T combine(T previousValue, E element)) → T
  Reduces a collection to a single value by iteratively combining each element of the collection with an existing value [...]
  inherited
followedBy(Iterable<E> other) → Iterable<E>
  Returns the lazy concatentation of this iterable and `other`. [...]
  inherited
forEach(void f(E element)) → void
  Applies the function `f` to each element of this collection in iteration order.
  inherited
join([String separator = ""]) → String
  Converts each element to a String and concatenates the strings. [...]
  inherited
lastWhere(bool test(E element), {E orElse()}) → E
  Returns the last element that satisfies the given predicate `test`. [...]
  inherited
map<T>(T f(E e)) → Iterable<T>
  Returns a new lazy Iterable with elements that are created by calling `f` on each element of this `Iterable` in iteration order. [...]
  inherited
noSuchMethod(Invocation invocation) → dynamic
  Invoked when a non-existent method or property is accessed. [...]
  inherited
reduce(E combine(E value, E element)) → E
  Reduces a collection to a single value by iteratively combining elements of the collection using the provided function. [...]
  inherited
singleWhere(bool test(E element), {E orElse()}) → E
  Returns the single element that satisfies `test`. [...]
  inherited
skip(int count) → Iterable<E>
  Returns an Iterable that provides all but the first `count` elements. [...]
  inherited
skipWhile(bool test(E value)) → Iterable<E>
  Returns an `Iterable` that skips leading elements while `test` is satisfied. [...]
  inherited
take(int count) → Iterable<E>
  Returns a lazy iterable of the `count` first elements of this iterable. [...]
  inherited
takeWhile(bool test(E value)) → Iterable<E>
  Returns a lazy iterable of the leading elements satisfying `test`. [...]
  inherited
toList({bool growable: true}) → List<E>
  Creates a List containing the elements of this Iterable. [...]
  inherited
toSet() → Set<E>
  Creates a Set containing the same elements as this iterable. [...]
  inherited
toString() → String
  Returns a string representation of (some of) the elements of `this`. [...]
  inherited
where(bool test(E element)) → Iterable<E>
  Returns a new lazy Iterable with all elements that satisfy the predicate `test`. [...]
  inherited
whereType<T>() → Iterable<T>
  Returns a new lazy Iterable with all elements that have type `T`. [...]

## Operators

operator ==(Object other) → bool
  The equality operator. [...]

## Static Methods

iterableToFullString(Iterable iterable, [String leftDelimiter = '(', String rightDelimiter = ')']) → String
  Converts an `Iterable` to a string. [...]
iterableToShortString(Iterable iterable, [String leftDelimiter = '(', String rightDelimiter = ')']) → String
  Convert an `Iterable` to a string like IterableBase.toString. [...]
