Properties
- first → E
-
Returns the first element. [...]
read-only, override
- isEmpty → bool
-
Returns
true
if there are no elements in this collection. [...]read-only, override - isNotEmpty → bool
-
Returns true if there is at least one element in this collection. [...]
read-only, override
- last → E
-
Returns the last element. [...]
read-only, override
- length → int
-
Returns the number of elements in this. [...]
read-only, override
- single → E
-
Checks that this iterable has only one element, and returns that element. [...]
read-only, override
- hashCode → int
-
The hash code for this object. [...]
read-only, inherited
-
iterator
→ Iterator<

Returns a new
Iterator
that allows iterating the elements of thisIterable
. [...]read-only, inherited - runtimeType → Type
-

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