Properties

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

Methods

any(bool test(E element)) → bool override: Checks whether any element of this iterable satisfies test. [...]
cast<R>() → Iterable<R> override: Provides a view of this iterable as an iterable of R instances. [...]
contains(Object? element) → bool override: Whether the collection contains an element equal to element. [...]
elementAt(int index) → E override: Returns the indexth element. [...]
every(bool f(E element)) → bool override: Checks whether every element of this iterable satisfies test. [...]
expand<T>(Iterable<T> f(E element)) → Iterable<T> override: Expands each element of this Iterable into zero or more elements. [...]
firstWhere(bool test(E value), {E orElse()}) → E override: Returns the first element that satisfies the given predicate test. [...]
fold<T>(T initialValue, T combine(T previousValue, E element)) → T override: Reduces a collection to a single value by iteratively combining each element of the collection with an existing value [...]
followedBy(Iterable<E> other) → Iterable<E> override: Returns the lazy concatenation of this iterable and other. [...]
forEach(void f(E element)) → void override: Applies the function f to each element of this collection in iteration order.
join([String separator = ""]) → String override: Converts each element to a String and concatenates the strings. [...]
lastWhere(bool test(E value), {E orElse()}) → E override: Returns the last element that satisfies the given predicate test. [...]
map<T>(T f(E element)) → Iterable<T> override: Returns a new lazy Iterable with elements that are created by calling f on each element of this Iterable in iteration order. [...]
noSuchMethod(Invocation invocation) → dynamic inherited: Invoked when a non-existent method or property is accessed. [...]
reduce(E combine(E value, E element)) → E override: Reduces a collection to a single value by iteratively combining elements of the collection using the provided function. [...]
singleWhere(bool test(E element), {E orElse()}) → E override: Returns the single element that satisfies test. [...]
skip(int count) → Iterable<E> override: Returns an Iterable that provides all but the first count elements. [...]
skipWhile(bool test(E value)) → Iterable<E> override: Returns an Iterable that skips leading elements while test is satisfied. [...]
take(int count) → Iterable<E> override: Returns a lazy iterable of the count first elements of this iterable. [...]
takeWhile(bool test(E value)) → Iterable<E> override: Returns a lazy iterable of the leading elements satisfying test. [...]
toList({bool growable = true}) → List<E> override: Creates a List containing the elements of this Iterable. [...]
toSet() → Set<E> override: Creates a Set containing the same elements as this iterable. [...]
toString() → String override: A string representation of this object. [...]
where(bool f(E element)) → Iterable<E> override: Returns a new lazy Iterable with all elements that satisfy the predicate test. [...]
whereType<T>() → Iterable<T> override: Returns a new lazy Iterable with all elements that have type T. [...]

Operators

operator ==(Object other) → bool inherited: The equality operator. [...]
