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

Properties

first → E
The first element.
read-onlyinherited
hashCode → int
The hash code for this object.
read-onlyinherited
hasListeners → bool
Whether any listeners are currently registered.
read-onlyinherited
isEmpty → bool
Whether this collection has no elements.
read-onlyinherited
isNotEmpty → bool
Whether this collection has at least one element.
read-onlyinherited
iterator → Iterator<E>
A new Iterator that allows iterating the elements of this Iterable.
read-onlyinherited
last → E
The last element.
read-onlyinherited
length → int
The number of elements in this.
read-onlyinherited
runtimeType → Type
A representation of the runtime type of the object.
read-onlyinherited
single → E
Checks that this iterable has only one element, and returns that element.
read-onlyinherited
value → Set<E>
The current value of the object. When the value changes, the callbacks registered with addListener will be invoked.
read-onlyoverride

Methods

add(E value) → bool
Adds value to the set.
addAll(Iterable<E> elements) → void
Adds all elements to this set.
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>() → Set<T>
A view of this iterable as an iterable of R instances.
inherited
clear() → void
Removes all elements from the set.
contains(Object? element) → bool
Whether the collection contains an element equal to element.
inherited
containsAll(Iterable<Object?> other) → bool
Whether this set contains all the elements of other.
inherited
difference(Set<Object?> other) → Set<E>
Creates a new set with the elements of this that are not in other.
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
intersection(Set<Object?> other) → Set<E>
Creates a new set which is the intersection between this set and other.
inherited
invert(E element) → bool
Removes if value exists, adds if not. Useful for checkbox like widgets
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
lookup(Object? element) → E?
If an object equal to object is in the set, return it.
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? value) → bool
Removes value from the set.
removeAll(Iterable<Object?> elements) → void
Removes each element of elements from this set.
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 e)) → void
Removes all elements of this set that satisfy test.
retainAll(Iterable<Object?> elements) → void
Removes all elements of this set that are not elements in elements.
retainWhere(bool test(E e)) → void
Removes all elements of this set that fail to satisfy test.
retype<T>() → Set<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
union(Set<E> other) → Set<E>
Creates a new set which contains all the elements of this set and other.
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.
