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
- first → E
-
read-only, inherited
Returns the first element.…
- isEmpty → bool
-
read-only, inherited
Returns
true
if there are no elements in this collection.… - isNotEmpty → bool
-
read-only, inherited
Returns true if there is at least one element in this collection.…
- iterator → Iterator<E>
-
read-only, inherited
Returns a new
Iterator
that allows iterating the elements of thisIterable
.… - last → E
-
read-only, inherited
Returns the last element.…
- length → int
-
read-only, inherited
Returns the number of elements in
this
.… - single → E
-
read-only, inherited
Checks that this iterable has only one element, and returns that element.…

Methods
-
any(
bool f(E element)) → bool -
inherited

element

elementAt(
int index) → E -
inherited
Returns the
index
th element.… -
every(
bool f(E element)) → bool -
inherited
Checks whether every element of this iterable satisfies
test
.… -
expand(
Iterable f(E element)) → Iterable -
inherited
Expands each element of this Iterableinto zero or more elements.…
-
firstWhere(
bool test(E element), {E orElse()}) → E -
inherited
Returns the first element that satisfies the given predicate
test
.… -
fold(
initialValue, dynamic combine(previousValue, E element)) → dynamic -
inherited
Reduces a collection to a single value by iteratively combining each element of the collection with an existing value…
-
forEach(
void f(E element)) → void -
inherited
Applies the function
f
to each element of this collection in iteration order. -
join(
[String separator = ""]) → String -
inherited
Converts each element to a String and concatenates the strings.…
-
lastWhere(
bool test(E element), {E orElse()}) → E -
inherited
Returns the last element that satisfies the given predicate
test
.… -
map(
dynamic f(E element)) → Iterable -
inherited
Returns 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 -
inherited
Reduces a collection to a single value by iteratively combining elements of the collection using the provided function.…
-
singleWhere(
bool test(E element)) → E -
inherited
Returns the single element that satisfies
test
.… -
skip(
int count) → Iterable<E> -
inherited
Returns an Iterable that provides all but the first
count
elements.… -
skipWhile(
bool test(E value)) → Iterable<E> -
inherited
Returns an Iterable that skips leading elements while
test
is satisfied.… -
take(
int count) → Iterable<E> -
inherited
Returns a lazy iterable of the
count
first elements of this iterable.… -
takeWhile(
bool test(E value)) → Iterable<E> -
inherited
Returns a lazy iterable of the leading elements satisfying
test
.… -
toList(
{bool growable: true}) → List<E> -
inherited
-
toSet(
) → Set<E> -
inherited
Creates a Set containing the same elements as this iterable.…
-
toString(
) → String -
inherited
Returns a string representation of (some of) the elements of
this
.… -
where(
bool f(E element)) → Iterable<E> -
inherited
Returns a new lazy Iterable with all elements that satisfy the predicate
test
