$Set class - core library

$Set.wrap(Set<E> $value): Wrap a Set in a $Set

Properties

$reified → Set: Fully reify the underlying value so it can be used in a Dart context. For example, recursively transform collections into their underlying $values.

no setter
length → int: The number of elements in this Iterable.
no setteroverride
nonNulls → Iterable<T>: Available on Iterable<T?>, provided by the NullableIterableExtensions extension
The non-null elements of this iterable.
no setter
runtimeType → Type: A representation of the runtime type of the object.

no setteroverride
singleOrNull → T?: Available on Iterable<T>, provided by the IterableExtensions extension
The single element of this iterator, or null.
no setter
toJSIterable → JSIterable<T>: Available on Iterable<T>, provided by the IterableToJSIterable extension
A JSIterable wrapper that proxies to the Dart iterable API.

wait → Future<List<T>>: Available on Iterable<Future<T>>, provided by the FutureIterable extension
Waits for futures in parallel.
no setter

Methods

$getProperty(Runtime runtime, String identifier) → $Value?: Get a property by identifier on this instance
override
$getRuntimeType(Runtime runtime) → int: Index of the class Type in the runtime dictionary. By definition can change from run to run, so it's customary to use Runtime.lookupType in implementations.
override

override
any(bool test(E value)) → bool: Checks whether any element of this iterable satisfies test.
override
asNameMap() → Map<String, T>: Available on Iterable<T>, provided by the EnumByName extension
Creates a map from the names of enum values to the values.
byName(String name) → T: Available on Iterable<T>, provided by the EnumByName extension
Finds the enum value in this list with name name.
cast<R>() → Set<R>: Provides a view of this set as a set of R instances.
override
clear() → void: Removes all elements from the set.
override
contains(Object? value) → bool: Whether value is in the set.
override
containsAll(Iterable<Object?> other) → bool: Whether this set contains all the elements of other.
override
difference(Set<Object?> other) → Set<E>: Creates a new set with the elements of this that are not in other.
override
elementAt(int index) → E: Returns the indexth element.
override
elementAtOrNull(int index) → T?: Available on Iterable<T>, provided by the IterableExtensions extension
The element at position index of this iterable, or null.
every(bool test(E value)) → bool: Checks whether every element of this iterable satisfies test.
override
expand<T>(Iterable<T> toElements(E element)) → Iterable<T>: Expands each element of this Iterable into zero or more elements.
override
firstWhere(bool test(E value), {E orElse()?}) → E: The first element that satisfies the given predicate test.
override
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
override
followedBy(Iterable<E> other) → Iterable<E>: Creates the lazy concatenation of this iterable and other.
override
forEach(void action(E element)) → void: Invokes action on each element of this iterable in iteration order.
override
intersection(Set<Object?> other) → Set<E>: Creates a new set which is the intersection between this set and other.
override
join([String separator = ""]) → String: Converts each element to a String and concatenates the strings.
override
lastWhere(bool test(E value), {E orElse()?}) → E: The last element that satisfies the given predicate test.
override
lookup(Object? object) → E?: If an object equal to object is in the set, return it.
override
map<T>(T toElement(E e)) → Iterable<T>: The current elements of this iterable modified by toElement.
override
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
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
remove(Object? value) → bool: Removes value from the set.
override

override
removeWhere(bool test(E value)) → void: Removes all elements of this set that satisfy test.
override
retainAll(Iterable<Object?> elements) → void: Removes all elements of this set that are not elements in elements.
override
retainWhere(bool test(E value)) → void: Removes all elements of this set that fail to satisfy test.
override
singleWhere(bool test(E value), {E orElse()?}) → E: The single element that satisfies test.
