Properties
-
first
→ E
-
The first element.
no setteroverride
-
hashCode
→ int
-
The hash code for this object.
no setteroverride
-
hasListeners
→ bool
-
Whether any listeners are currently registered.
no setterinherited
-
isEmpty
→ bool
-
Whether this collection has no elements.
no setteroverride
-
isNotEmpty
→ bool
-
Whether this collection has at least one element.
no setteroverride
-
iterator
→ Iterator<E>
-
A new
Iterator
that allows iterating the elements of this Iterable
.
no setteroverride
-
last
→ E
-
The last element.
no setteroverride
-
length
→ int
-
The number of elements in this.
no setteroverride
-
runtimeType
→ Type
-
A representation of the runtime type of the object.
no setterinherited
-
single
→ E
-
Checks that this iterable has only one element, and returns that element.
no setteroverride
-
value
→ T
-
The current value of the object. When the value changes, the callbacks
registered with addListener will be invoked.
no setteroverride
Methods
-
addListener(VoidCallback listener)
→ void
-
Register a closure to be called when the object changes.
inherited
-
any(bool test(E element))
→ bool
-
Checks whether any element of this iterable satisfies
test
.
override
-
cast<R>()
→ Iterable<R>
-
A view of this iterable as an iterable of
R
instances.
override
-
contains(Object? element)
→ bool
-
Whether the collection contains an element equal to
element
.
override
-
dispose()
→ void
-
Discards any resources used by the object. After this is called, the
object is not in a usable state and should be discarded (calls to
addListener will throw after the object is disposed).
inherited
-
elementAt(int index)
→ E
-
Returns the
index
th element.
override
-
every(bool test(E element))
→ bool
-
Checks whether every element of this iterable satisfies
test
.
override
-
expand<S>(Iterable<S> f(E element))
→ Iterable<S>
-
Expands each element of this Iterable into zero or more elements.
override
-
firstWhere(bool test(E element), {E orElse()?})
→ E
-
The first element that satisfies the given predicate
test
.
override
-
fold<S>(S initialValue, S combine(S previousValue, E element))
→ S
-
Reduces a collection to a single value by iteratively combining each
element of the collection with an existing value
override
-
followedBy(Iterable<E> other)
→ Iterable<E>
-
Creates the lazy concatenation of this iterable and
other
.
override
-
forEach(void f(E element))
→ void
-
Invokes
action
on each element of this iterable in iteration order.
override
-
join([String separator = ""])
→ String
-
Converts each element to a String and concatenates the strings.
override
-
lastWhere(bool test(E element), {E orElse()?})
→ E
-
The last element that satisfies the given predicate
test
.
override
-
map<S>(S f(E e))
→ Iterable<S>
-
The current elements of this iterable modified by
toElement
.
override
-
noSuchMethod(Invocation invocation)
→ dynamic
-
Invoked when a nonexistent method or property is accessed.
inherited
-
notifyListeners()
→ void
-
Call all the registered listeners.
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.
override
-
removeListener(VoidCallback listener)
→ void
-
Remove a previously registered closure from the list of closures that are
notified when the object changes.
inherited
-
singleWhere(bool test(E element), {E orElse()?})
→ E
-
The single element that satisfies
test
.
override
-
skip(int count)
→ Iterable<E>
-
Creates an Iterable that provides all but the first
count
elements.
override
-
skipWhile(bool test(E value))
→ Iterable<E>
-
Creates an
Iterable
that skips leading elements while test
is satisfied.
override
-
take(int count)
→ Iterable<E>
-
Creates a lazy iterable of the
count
first elements of this iterable.
override
-
takeWhile(bool test(E value))
→ Iterable<E>
-
Creates a lazy iterable of the leading elements satisfying
test
.
override
-
toList({bool growable = true})
→ List<E>
-
Creates a List containing the elements of this Iterable.
override
-
toSet()
→ Set<E>
-
Creates a Set containing the same elements as this iterable.
override
-
toString()
→ String
-
A string representation of this object.
override
-
where(bool test(E element))
→ Iterable<E>
-
Creates a new lazy Iterable with all elements that satisfy the
predicate
test
.
override
-
whereType<S>()
→ Iterable<S>
-

T
.
