Methods

map(dynamic f(E element)) → Iterable
Returns a new lazy [Iterable] with elements that are created by calling f on each element of this Iterable in iteration order.
where(bool f(E element)) → Iterable<E>
Returns a new lazy [Iterable] with all elements that satisfy the predicate [test].
expand(Iterable f(E element)) → Iterable
Expands each element of this [Iterable]into zero or more elements.
contains(Object element) → bool
Returns true if the collection contains an element equal to [element].
forEach(void f(E element)) → void
Applies the function [f] to each element of this collection 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.
fold(initialValue, dynamic combine(previousValue, E element)) → dynamic
Reduces a collection to a single value by iteratively combining each element of the collection with an existing value
every(bool f(E element)) → bool
Checks whether every element of this iterable satisfies [test].
join([String separator = ""]) → String
Converts each element to a [String] and concatenates the strings.
any(bool f(E element)) → bool
Checks whether any element of this iterable satisfies [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.
take(int n) → 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].
skip(int n) → 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.
firstWhere(bool test(E value), {E orElse()}) → E
Returns the first element that satisfies the given predicate [test].
lastWhere(bool test(E value), {E orElse()}) → E
Returns the last element that satisfies the given predicate [test].
singleWhere(bool test(E value)) → E
Returns the single element that satisfies [test].
elementAt(int index) → E
Returns the [index]th element.
toString() → String
Returns a string representation of this object.
