(
Iterable
<
String
>
iterable

take
(
int
n

Iterable
<
String
>
inherited
Returns a lazy iterable of the count first elements of this iterable.
map
(
dynamic
f
(
E
element
)
) →
Iterable
inherited
Returns a new lazy
Iterable
with elements that are created by calling f on each element of this Iterable in iteration order.
intersection
(
Set
<
Object
>
other
) →
Set

takeWhile
(
bool
test
(
E
value
)
) →
Iterable
<
String
>
inherited
Returns a lazy iterable of the leading elements satisfying test.
fold
(
initialValue
,
dynamic
combine
(
previousValue
,
E
element
)
) →
dynamic
inherited
Reduces a collection to a single value by iteratively combining each element of the collection with an existing value
toSet
(
) →
Set
<
String
>
inherited
Creates a [Set] containing the same elements as this iterable.
firstWhere
(
bool
test
(
E
element
)
, {
E
orElse
()
}) →
String
inherited
Returns the first element that satisfies the given predicate test.
forEach
(
void
f
(
E
element
)
) →
void
inherited
Applies the function f to each element of this collection in iteration order.
difference
(
Set
<
String
>
other
) →
Set
<
String
>
inherited
Returns a new set with the the elements of this that are not in other.
skipWhile
(
bool
test
(
E
value
)
) →
Iterable
<
String
>
inherited
Returns an Iterable that skips leading elements while test is satisfied.
join
(
[
String
separator
=
""
]) →
String
inherited
Converts each element to a
String
and concatenates the strings.
union
(
Set
<
String
>
other
) →
Set
<
String
>
inherited
Returns a new set which contains all the elements of this set and other.
lastWhere

(
E
element
)
) →
String
inherited

reduce
(
E
combine
(
