read-only
last → E
Returns the last element. [...]
read-only
length → int

Methods

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