Methods

any(bool f(E element)) bool

Checks whether any element of this iterable satisfies test.

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

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 value)) → 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.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a non-existent method or property is accessed.
