Methods

every(bool f(T element)) bool
Checks whether every element of this iterable satisfies test. [...]
override
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
forEach(void f(T element)) → void
Applies the function f to each element of this collection 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
Returns the last element that satisfies the given predicate test. [...]
override
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
Returns the single element that satisfies test. [...]
override
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
any(bool test(T element)) bool
Checks whether any element of this iterable satisfies test. [...]
inherited
cast<R>() Iterable<R>
Provides a view of this iterable as an iterable of R instances. [...]
inherited
contains(Object element) bool
Returns true if the collection contains an element equal to element. [...]
inherited
elementAt(int index) → T
Returns the indexth element. [...]
inherited
expand<T>(Iterable<T> f(T element)) Iterable<T>
Expands each element of this Iterable into zero or more elements. [...]
inherited
firstWhere(bool test(T element), { T orElse() }) → T
Returns the first element that satisfies the given predicate test. [...]
inherited
followedBy(Iterable<T> other) Iterable<T>
Returns the lazy concatentation of this iterable and other. [...]
inherited
map<T>(T f(T e)) Iterable<T>
Returns a new lazy Iterable with elements that are created by calling f on each element of this Iterable in iteration order. [...]
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
inherited
skip(int count) Iterable<T>
Returns an Iterable that provides all but the first count elements. [...]
inherited
skipWhile(bool test(T value)) Iterable<T>
Returns an Iterable that skips leading elements while test is satisfied. [...]
inherited
take(int count) Iterable<T>
Returns a lazy iterable of the count first elements of this iterable. [...]
inherited
takeWhile(bool test(T value)) Iterable<T>
Returns a lazy iterable of the leading elements satisfying test. [...]
inherited
toString() String
Returns a string representation of (some of) the elements of this. [...]
inherited
where(bool test(T element)) Iterable<T>
Returns a new lazy Iterable with all elements that satisfy the predicate test. [...]
inherited
