Properties

first → Object?
The first element.
no setterinherited
hashCode → int
The hash code for this object.
no setterinherited
isEmpty → bool
Whether this collection has no elements.
no setterinherited
isNotEmpty → bool
Whether this collection has at least one element.
no setterinherited
iterator → Iterator<Object?>

Methods

any(bool test(Object? element)) → bool
Checks whether any element of this iterable satisfies test.
inherited
array(int index) → Array?
Returns the element at the given index as an Array.
inherited
blob(int index) → Blob?
Returns the element at the given index as a Blob.
inherited
boolean(int index) → bool
Returns the element at the given index as a bool.
inherited
cast<R>() → Iterable<R>
A view of this iterable as an iterable of R instances.
inherited
contains(Object? element) → bool
Whether the collection contains an element equal to element.
inherited
date(int index) → DateTime?
Returns the element at the given index as a DateTime.
inherited
dictionary(int index) → Dictionary?
Returns the element at the given index as a Dictionary.
inherited
elementAt(int index) → Object?
Returns the indexth element.
inherited
every(bool test(Object? element)) → bool

inherited
expand<T>(Iterable<T> toElements(Object? element)) → Iterable<T>
Expands each element of this Iterable into zero or more elements.
inherited
firstWhere(bool test(Object? element), {Object? orElse()?}) → Object?
The first element that satisfies the given predicate test.
inherited
float(int index) → double
Returns the element at the given index as an floating point number.
inherited
fold<T>(T initialValue, T combine(T previousValue, Object? element)) → T
Reduces a collection to a single value by iteratively combining each element of the collection with an existing value
inherited
followedBy(Iterable<Object?> other) → Iterable<Object?>
Creates the lazy concatenation of this iterable and other.
inherited
forEach(void action(Object? element)) → void
Invokes action on each element of this iterable in iteration order.
inherited
integer(int index) → int
Returns the element at the given index as an integer number.
inherited
join([String separator = ""]) → String
Converts each element to a String and concatenates the strings.
inherited
lastWhere(bool test(Object? element), {Object? orElse()?}) → Object?
The last element that satisfies the given predicate test.
inherited
map<T>(T toElement(Object? e)) → Iterable<T>
The current elements of this iterable modified by toElement.
inherited

inherited
number(int index) → num?
Returns the element at the given index as a num.
inherited
reduce(Object? combine(Object? value, Object? element)) → Object?
Reduces a collection to a single value by iteratively combining elements of the collection using the provided function.
inherited
singleWhere(bool test(Object? element), {Object? orElse()?}) → Object?

Creates a List containing the elements of this Iterable.
inherited
toMutable() → MutableArray
