Methods

add(V value) bool
Adds value to the set. [...]
inherited
addAll(Iterable<V> elements) → void
Adds all elements to this set. [...]
inherited
any(bool test(V element)) bool
Checks whether any element of this iterable satisfies test. [...]
inherited
cast<T>() Set<T>
Provides a view of this iterable as an iterable of R instances. [...]
override
clear() → void
Removes all elements from the set.
inherited
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<V>
Creates a new set with the elements of this that are not in other. [...]
inherited
elementAt(int index) → V
Returns the indexth element. [...]
inherited
every(bool test(V element)) bool
Checks whether every element of this iterable satisfies test. [...]
inherited
expand<T>(Iterable<T> f(V element)) Iterable<T>
Expands each element of this Iterable into zero or more elements. [...]
inherited
firstWhere(bool test(V element), {V orElse()?}) → V
Returns the first element that satisfies the given predicate test. [...]
inherited
fold<T>(T initialValue, T combine(T previousValue, V element)) → T
Reduces a collection to a single value by iteratively combining each element of the collection with an existing value [...]
inherited
followedBy(Iterable<V> other) Iterable<V>
Returns the lazy concatenation of this iterable and other. [...]
inherited
forEach(void f(V element)) → void
Applies the function f to each element of this collection in iteration order.
inherited
fromIterator(V anchor, {bool reversed = false, bool inclusive = true}) BidirectionalIterator<V>
Returns an BidirectionalIterator that starts at anchor. By default, the iterator includes the anchor with the first movement; set inclusive to false if you want to exclude the anchor. Set reversed to true to change the direction of of moveNext and movePrevious. [...]
intersection(Set<Object?> other) Set<V>
Creates 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(V element), {V orElse()?}) → V
Returns the last element that satisfies the given predicate test. [...]
inherited
lookup(Object? object) → V?
If an object equal to object is in the set, return it. [...]
inherited
map<T>(T f(V e)) 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
nearest(V object, {TreeSearch nearestOption = TreeSearch.NEAREST}) → V
Search the tree for the matching object or the nearestOption if missing. See TreeSearch.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
inherited
reduce(V combine(V value, V element)) → V
Reduces a collection to a single value by iteratively combining elements of the collection using the provided function. [...]
inherited
remove(Object? value) bool

inherited
retainAll(Iterable<Object?> elements) → void
Removes all elements of this set that are not elements in elements. [...]
inherited
retainWhere(bool test(V element)) → void
Removes all elements of this set that fail to satisfy test.
inherited
singleWhere(bool test(V element), {V orElse()?}) → V
