Properties

first → E
Returns the first element.
read-onlyoverride
hashCode int
The hash code for this object.
read-onlyinherited
isEmpty bool
Whether this collection has no elements.
read-onlyoverride
isNotEmpty bool
Whether this collection has at least one element.
read-onlyoverride
iterator Iterator<E>
Returns a new Iterator that allows iterating the elements of this Iterable.
read-onlyinherited
last → E
Returns the last element.
read-onlyoverride
length int
Returns the number of elements in this.
read-onlyoverride
runtimeType Type
A representation of the runtime type of the object.
read-onlyinherited
single → E
Checks that this iterable has only one element, and returns that element.
read-onlyoverride

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 an Iterable that skips leading elements while test is satisfied.
override
take(int count) 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
whereType<T>() Iterable<T>
Returns a new lazy Iterable with all elements that have type T.
override
