Checks whether every element of this iterable satisfies
test.
inherited
-
expand<T>(Iterable<T> toElements(E element))
→ Iterable<T>
-
Expands each element of this Iterable into zero or more elements.
inherited
-
firstWhere(bool test(E element), {E orElse()?})
→ E
-
The first element that satisfies the given predicate
test.
inherited
-
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
inherited
-
followedBy(Iterable<E> other)
→ Iterable<E>
-
Creates the lazy concatenation of this iterable and
other.
inherited
-
forEach(void action(E element))
→ void
-

action on each element of this iterable in iteration order.
inherited
-
join([String separator = ""])
→ String
-
Converts each element to a String and concatenates the strings.
inherited
-
lastWhere(bool test(E element), {E orElse()?})
→ E
-
The last element that satisfies the given predicate
test.
inherited
-
map<T>(T toElement(E 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(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.
inherited
-

→ E
-
The single element that satisfies
test.
inherited
-
skip(int count)

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

count first elements of this iterable.
inherited
-
