any(
bool test(T element)) → bool -
Checks whether any element of this iterable satisfies
test.inherited -
asList(

expand<
U> (Iterable< U> f(T)) → Iter<U> -
Expands each element of this Iterable into zero or more elements.
override
-
first(
) → Option< T> - Returns the first element of an iterator, None if empty.
-
firstWhere(
bool test(T element), {T orElse()?}) → T -
The first element that satisfies the given predicate
test.inherited -
fold<
T> (T initialValue, T combine(T previousValue, T element)) → T -
Reduces a collection to a single value by iteratively combining each
element of the collection with an existing value
inherited
-
followedBy(
Iterable< T> other) → Iter<T> -
Creates the lazy concatenation of this iterable and
other.override -
forEach(
void action(T element)) → void -
Invokes
actionon each element of this iterable in iteration order.inherited -
isEmpty(
) → bool - Returns true if the iterator is empty, false otherwise.

isNotEmpty(
) → bool - Returns true if the iterator is not empty, false otherwise.
-
join(
[String separator = ""]) → String -
Converts each element to a String and concatenates the strings.
inherited
-
last(
) → Option< T> - Returns the last element of an iterator, None if empty.
-
lastWhere(
bool test(T element), {T orElse()?}) → T -
The last element that satisfies the given predicate
test.inherited -
len(
) → int - Returns the length of an iterator.
-
map<
U> (U f(T)) → Arr< U> -
Returns an array of the same size as self, with function f applied to each element in order.
override
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
reduce(
T combine(T value, T element)) → T -

of the collection using the provided function.
inherited
-
rsplitSlice(
int index) → (Slice< T> , Slice<T> ) - Divides array into two Slices at index from end. The first will contain all indices from [0, N - M) (excluding the index N - M itself) and the second will contain all indices from [N - M, N) (excluding the index N itself).
-
single(
) → Option< T> - Returns the single element of an iterator, None if this is empty or has more than one element.
-
