QueueNotifier([Iterable<E> base = const []])

Properties

first → E
The first element.
no setterinherited
hashCode → int
The hash code for this object.
no setterinherited
hasListeners → bool
Whether any listeners are currently registered.
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<E>
A new Iterator that allows iterating the elements of this Iterable.
no setterinherited
last → E
The last element.
no setterinherited
length → int
The number of elements in this.
no setterinherited
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 setterinherited
value → Queue<E>
The current value of the object. When the value changes, the callbacks registered with addListener will be invoked.
no setteroverride

Methods

add(E value) → void
Adds value at the end of the queue.
inherited
addAll(Iterable<E> iterable) → void
Adds all elements of iterable at the end of the queue. The length of the queue is extended by the length of iterable.
addFirst(E value) → void
Adds value at the beginning of the queue.
addLast(E value) → void
Adds value at the end of the queue.
addListener(VoidCallback listener) → void
Register a closure to be called when the object changes.
inherited
any(bool test(E)) → bool
Checks whether any element of this iterable satisfies test.
inherited
cast<T>() → Queue<T>
A view of this iterable as an iterable of R instances.
inherited
clear() → void
Removes all elements in the queue. The size of the queue becomes zero.
contains(Object? element) → bool
Whether the collection contains an element equal to element.
inherited
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 indexth element.
inherited
every(bool test(E)) → bool
Checks whether every element of this iterable satisfies test.
inherited
expand<T>(Iterable<T> f(E)) → Iterable<T>
Expands each element of this Iterable into zero or more elements.
inherited
firstWhere(bool test(E), {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 f(E)) → void
Invokes 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), {E orElse()?}) → E
The last element that satisfies the given predicate test.
inherited
map<T>(T f(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
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.
inherited
remove(Object? object) → bool
Removes a single instance of value from the queue.
removeFirst() → E
Removes and returns the first element of this queue.
removeLast() → E
Removes and returns the last element of the queue.
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
removeWhere(bool test(E element)) → void
Removes all elements matched by test from the queue.
retainWhere(bool test(E element)) → void
Removes all elements not matched by test from the queue.
retype<T>() → Queue<T>
inherited
singleWhere(bool test(E), {E orElse()?}) → E
The single element that satisfies test.
inherited
skip(int n) → Iterable<E>
Creates an Iterable that provides all but the first count elements.
inherited
skipWhile(bool test(E)) → Iterable<E>
Creates an Iterable that skips leading elements while test is satisfied.
inherited
take(int n) → Iterable<E>
Creates a lazy iterable of the count first elements of this iterable.
inherited
takeWhile(bool test(E)) → Iterable<E>
Creates a lazy iterable of the leading elements satisfying test.
inherited
toList({bool growable = true}) → List<E>
Creates a List containing the elements of this Iterable.
inherited
toSet() → Set<E>
Creates a Set containing the same elements as this iterable.
inherited
toString() → String
A string representation of this object.
inherited
where(bool test(E)) → Iterable<E>
Creates a new lazy Iterable with all elements that satisfy the predicate test.
inherited
whereType<T>() → Iterable<T>
Creates a new lazy Iterable with all elements that have type T.
