element of iterable
and its index. See enumerate.

Methods
-
elementAt(
int index) → IndexedValue< V> -
Returns the
index
th element. [...]override -
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 -
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), { IndexedValue< V> orElse() }) → IndexedValue< V> -
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< IndexedValue< V>> other) → Iterable< IndexedValue< V>> -
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), { IndexedValue< V> orElse() }) → IndexedValue< V> -
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 thisIterable
in iteration order. [...]inherited -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a non-existent method or property is accessed. [...]
inherited
-
reduce(
IndexedValue< V> combine(E value, E element)) → IndexedValue< V> -
Reduces a collection to a single value by iteratively combining elements
of the collection using the provided function. [...]
inherited
-
singleWhere(
bool test(E element), { IndexedValue< V> orElse() }) → IndexedValue< V> -
Returns the single element that satisfies
test
. [...]inherited -
skip(
int count) → Iterable< IndexedValue< V>> -
Returns an Iterable that provides all but the first
count
elements. [...]inherited -
skipWhile(
bool test(E value)) → Iterable< IndexedValue< V>> -
Returns an
Iterable
that skips leading elements whiletest
is satisfied. [...]inherited -
take(
int count) → Iterable< IndexedValue< V>> -
Returns a lazy iterable of the
count
first elements of this iterable. [...]inherited -
takeWhile(
bool test(E value)) → Iterable< IndexedValue< V>> -
Returns a lazy iterable of the leading elements satisfying
test
. [...]inherited -
toList(
{bool growable: true }) → List< IndexedValue< V>> -
Creates a List containing the elements of this Iterable. [...]
inherited
-
toSet(
) → Set< IndexedValue< V>> -
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< IndexedValue< V>> -

predicate
test
. [...]inherited -
