Properties

first → T
The first element.
no setterinherited
hashCode → int
The hash code for this object.

Methods

any(bool test(T element)) → bool
Checks whether any element of this iterable satisfies test.
inherited
cast<R>() → Iterable<R>
A view of this iterable as an iterable of R instances.
inherited
contains(Object? element) → bool
Whether the collection contains an element equal to element.
inherited
elementAt(int index) → T
Returns the indexth element.
inherited
every(bool test(T element)) → bool
Checks whether every element of this iterable satisfies test.
override
expand<T>(Iterable<T> toElements(T element)) → Iterable<T>
Expands each element of this Iterable into zero or more elements.
inherited
firstWhere(bool test(T element), {T orElse()?}) → T
The first element that satisfies the given predicate test.
inherited
fold<T1>(T1 initialValue, T1 combine(T1 previousValue, T element)) → T1
Reduces a collection to a single value by iteratively combining each element of the collection with an existing value
override
followedBy(Iterable<T> other) → Iterable<T>
Creates the lazy concatenation of this iterable and other.
inherited
forEach(void action(T 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(T value), {T orElse()?}) → T
The last element that satisfies the given predicate test.
override
map<T>(T toElement(T e)) → Iterable<T>
The current elements of this iterable modified by toElement.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
reduce(T combine(T value, T element)) → T
Reduces a collection to a single value by iteratively combining elements of the collection using the provided function.
override
singleWhere(bool test(T value), {T orElse()?}) → T
The single element that satisfies test.
override
skip(int count) → Iterable<T>
Creates an Iterable that provides all but the first count elements.
inherited
skipWhile(bool test(T value)) → Iterable<T>
Creates an Iterable that skips leading elements while test is satisfied.
inherited
take(int count) → Iterable<T>
Creates a lazy iterable of the count first elements of this iterable.
inherited
takeWhile(bool test(T value)) → Iterable<T>
Creates a lazy iterable of the leading elements satisfying test.
inherited
toList({bool growable = true}) → List<T>
Creates a List containing the elements of this Iterable.
override
toSet() → Set<T>
Creates a Set containing the same elements as this iterable.
override
toString() → String
Returns a string representation of (some of) the elements of this.
inherited
where(bool test(T element)) → Iterable<T>
Creates a new lazy Iterable with all elements that satisfy the predicate test.
inherited
whereType<T>() → Iterable<T>
Creates a new lazy Iterable with all elements that have type T.
