Methods

add(T value) bool
Adds value to the set. Listeners are only notified if the set changes. [...]
override
addAll(Iterable<T> elements) → void
Adds all elements to this set. Listeners are notified after all values have been added. [...]
override
addListener(VoidCallback listener) → void
Register a closure to be called when the object changes. [...]
inherited
any(bool test(T element)) bool
Checks whether any element of this iterable satisfies test. [...]
inherited
cast<R>() Set<R>
Provides a view of this set as a set of R instances. [...]
inherited
clear() → void
Removes all elements in the set. Listeners are notified after all valuse have been removed.
override
contains(Object element) bool
Returns true if value is in the set.
override
containsAll(Iterable<Object> other) bool
Returns whether this Set contains all the elements of other.
inherited
difference(Set<Object> other) Set<T>
Returns a new set with the elements of this that are not in other. [...]
inherited
dispose() → void
Discards the internal resources used by the object. After this is called, the object is not in a usable state and should be discarded. [...]
@mustCallSuper, override
elementAt(int index) → T
Returns the indexth element. [...]
inherited
every(bool f(T element)) bool
Checks whether every element of this iterable satisfies test. [...]
inherited
expand<T>(Iterable<T> f(T element)) Iterable<T>
Expands each element of this Iterable into zero or more elements. [...]
inherited
firstWhere(bool test(T value), {T orElse()}) → T
Returns the first element that satisfies the given predicate test. [...]
inherited
fold<T>(T initialValue, T combine(T previousValue, T element)) → T
Reduces a collection to a single value by iteratively combining each element of the collection with an existing value [...]
inherited
followedBy(Iterable<T> other) Iterable<T>
Returns the lazy concatentation of this iterable and other. [...]
inherited
forEach(void f(T element)) → void
Applies the function f to each element of this collection in iteration order.
inherited
intersection(Set<Object> other) Set<T>
Returns a new set which is the intersection between this set and other. [...]
inherited
join([String separator = ""]) String
Converts each element to a String and concatenates the strings. [...]
inherited
lastWhere(bool test(T value), {T orElse()}) → T
Returns the last element that satisfies the given predicate test. [...]
inherited
lookup(Object element) → T
If an object equal to element is in the set, return it. [...]
override
map<T>(T f(T element)) Iterable<T>
Returns a new lazy Iterable with elements that are created by calling f on each element of this Iterable in iteration order. [...]
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
inherited
notifyListeners() → void
Notify all the listeners, respecting our paused state falg
inherited
pauseNotifications<T>(ChangeHandler<T> handler, [bool notifyAfter = false]) → T
Pause notifications until after a synchronous handler has completed. If notifyAfter is true, then listeners will automatically be notified after the callback completes. Otherwise, you must notify the listeners;
inherited
pauseNotificationsAsync<T>(AsyncChangeHandler<T> handler, [bool notifyAfter = false]) Future<T>
Pause notifications until after an asynchronous handler has completed. If notifyAfter is true, then listeners will automatically be notified after the callback completes. Otherwise, you must notify the listeners;
inherited
reduce(T combine(T value, T element)) → T
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. Returns true if value was in the set. Only notifies the listeners if the set was changed. [...]
override
removeAll(Iterable<Object> elements) → void
Removes each element of elements from this set. Listeners are notified after all values have been removed.
override
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(T element)) → void
Removes all elements of this set that satisfy test Listeners are notified after all values have been removed.
override
retainAll(Iterable<Object> elements) → void
Removes all elements of this set that are not elements in elements. Listeners are notified after all values have been removed. [...]
override
retainWhere(bool test(T element)) → void
Removes all elements of this set that fail to satisfy test Listeners are notified after all values have been removed.
override
singleWhere(bool test(T value), {T orElse()}) → T
Returns the single element that satisfies test. [...]
inherited
skip(int n) Iterable<T>
Returns an Iterable that provides all but the first count elements. [...]
inherited
skipWhile(bool test(T value)) Iterable<T>
