Base class for implementing Iterable.
This class implements all methods of Iterable except Iterable.iterator
in terms of iterator
.
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.
Properties
- E first
-
read-only, inheritedReturns the first element.
- bool isEmpty
-
read-only, inheritedReturns
true
if there are no elements in this collection. - bool isNotEmpty
-
read-only, inheritedReturns true if there is at least one element in this collection.
- Iterator<E> iterator
-
read-only, inheritedReturns a new
Iterator
that allows iterating the elements of thisIterable
. - E last
-
read-only, inheritedReturns the last element.
- int length
-
read-only, inheritedReturns the number of elements in
this
. - E single
-
read-only, inheritedChecks that this iterable has only one element, and returns that element.

Methods
-
any(
bool f(E element)) → bool -
inheritedChecks whether any element of this iterable satisfies
test
. -
contains(
Object element) → bool -
inheritedReturns true if the collection contains an element equal to
element
. -
elementAt(
int index) → E -
inheritedReturns the
index
th element. -
every(
bool f(E element)) → bool -
inheritedChecks whether every element of this iterable satisfies
test
. -
expand(
Iterable f(E element)) → Iterable -
inheritedExpands each element of this Iterableinto zero or more elements.
-
firstWhere(
bool test(E element), {E orElse()}) → E -
inheritedReturns the first element that satisfies the given predicate
test
. -
fold(
initialValue, dynamic combine(previousValue, E element)) → dynamic -
inheritedReduces a collection to a single value by iteratively combining each element of the collection with an existing value
-
forEach(
void f(E element)) → void -
inheritedApplies the function
f
to each element of this collection in iteration order. -
join(
[String separator = ""]) → String -
inheritedConverts each element to a String and concatenates the strings.
-
lastWhere(
bool test(E element), {E orElse()}) → E -
inheritedReturns the last element that satisfies the given predicate
test
. -
map(
dynamic f(E element)) → Iterable -
inheritedReturns a new lazy Iterable with elements that are created by calling
f
on each element of thisIterable
in iteration order. -
reduce(
E combine(E value, E element)) → E -
inheritedReduces a collection to a single value by iteratively combining elements of the collection using the provided function.
-
singleWhere(
bool test(E element)) → E -
inheritedReturns the single element that satisfies
test
. -
skip(
int count) → Iterable<E> -
inheritedReturns an Iterable that provides all but the first
count
elements. -
skipWhile(
bool test(E value)) → Iterable<E> -
inheritedReturns an Iterable that skips leading elements while
test
is satisfied. -
take(
int count) → Iterable<E> -
inheritedReturns a lazy iterable of the
count
first elements of this iterable. -
takeWhile(
bool test(E value)) → Iterable<E> -
inheritedReturns a lazy iterable of the leading elements satisfying
test
. -
toList(
{bool growable: true}) → List<E> -
inheritedCreates a List containing the elements of this Iterable.
-
toSet(
) → Set<E> -
inheritedCreates a Set containing the same elements as this iterable.
-
toString(
) → String -
inheritedReturns a string representation of (some of) the elements of
this
. -
where(
bool f(E element)) → Iterable<E> -
inheritedReturns a new lazy Iterable with all elements that satisfy the predicate
test
.
