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
Whether the collection contains an element equal to element. [...]
override
elementAt(int index) → E
Returns the indexth element. [...]
override
every(bool test(E element)) → bool
Checks whether every element of this iterable satisfies test. [...]
override
expand<T>(Iterable<T> toElements(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 concatenation of this iterable and other. [...]
override
forEach(void action(E element)) → void
Invokes action on each element of this iterable 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 toElement(E element)) → Iterable<T>
The current elements of this iterable modified by toElement. [...]
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
inherited
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 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
A string representation of this object. [...]
override
where(bool test(E element)) → Iterable<E>
Returns a new lazy Iterable with all elements that satisfy the predicate test. [...]
override
