Methods
-
any(bool test(E element))
→ bool

test. [...]
inherited
-
cast<R>()
→ Iterable<R>
-
Provides a view of this iterable as an iterable of
R instances. [...]
inherited
-
contains(Object element)
→ bool

element. [...]
inherited
-
elementAt(int index)
→ E
-
Returns the
indexth element. [...]
inherited
-
every(bool test(E element))
→ bool
-
Checks whether every element of this iterable satisfies
test. [...]
inherited
-
expand<T>(Iterable<T> f(E element))

Expands each element of this Iterable into zero or more elements. [...]
inherited
-
firstWhere(bool test(E element), { E orElse() })
→ E
-
Returns the first element that satisfies the given predicate
test. [...]
inherited
-
fold<T>(T initialValue, T combine(T previousValue, E element))
→ T
-

element of the collection with an existing value [...]
inherited
-
followedBy(Iterable<E> other)
→ Iterable<E>
-
Returns the lazy concatentation of this iterable and
other. [...]
inherited
-
forEach(void f(E element))
→ void
-

f to each element of this collection in iteration
order.
inherited
-
join([String separator = "" ])
→ String

inherited
-
lastWhere(bool test(E element), { E orElse() })
→ E
-
Returns the last element that satisfies the given predicate
test. [...]
inherited
-
map<T>(T f(E 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

→ dynamic
-
Invoked when a non-existent method or property is accessed. [...]
inherited
-
reduce(E combine(E value, E element))
→ E

count elements. [...]
inherited
-
skipWhile(bool test(E value))
→ Iterable<E>
