RxSet<T> class
An RxSet gives you a deeper level of observability on a set of values. It tracks when values are added, removed or modified and notifies the observers.
Use an RxSet when a change in the set matters.

Constructors
Properties
- first → T
-
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<
T> -
An iterator that iterates over the elements of this set.
no setteroverride
- key ↔ String
-
Atom Identify
latefinaloverride-getter
- last → T
-
The last element.
no setterinherited
- length → int
-
The number of elements in this.
no setteroverride
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- single → T
-
Checks that this iterable has only one element, and returns that element.
no setterinherited
-
value
→ RxSet<
T> -
The current value of the object. When the value changes, the callbacks
registered with addListener will be invoked.

Methods
-
add(
T value) → bool -
Adds
value
to the set.override -
addAll(
Iterable< T> elements) → void -
Adds all
elements
to this set.inherited -
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 -
buffer(
int count, {Duration timeLimit = const Duration(seconds: 10)}) → Future< List< RxSet< >T> > -
Buffer changes of a Atom.
The
count
is a number of a buffered items. ThetimeLimit
is 10 seconds by default.override -
cast<
R> () → Set< R> -
Provides a view of this set as a set of
R
instances.inherited -
clear(
) → void -
Removes all elements from the set.
override
-
contains(
Object? element) → bool -
Whether
value
is in the set.override -
containsAll(
Iterable< Object?> other) → bool -
Whether this set contains all the elements of
other
.inherited -
difference(
Set< Object?> other) → Set<T> -
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) → T -
Returns the
index
th 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 -
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> -
Creates the lazy concatenation of this iterable and
other
.inherited -
forEach(
void f(T element)) → void -
Invokes
action
on each element of this iterable in iteration order.inherited -
intersection(
Set< Object?> other) → Set<T> -
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(T value), {T orElse()?}) → T -
The last element that satisfies the given predicate
test
.inherited -
lookup(
Object? element) → T? -
If an object equal to
object
is in the set, return it.override -
map<
T> (T f(T element)) → Iterable< T> -
The current elements of this iterable modified by
toElement
.inherited -
next(
{Duration timeLimit = const Duration(seconds: 10)}) → Future< RxSet< T> > -
Wait the next change of a Atom.
The
timeLimit
is 10 seconds by default.override -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
notifyListeners(
) → void -
Call all the registered 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.override -
removeAll(
Iterable< Object?> elements) → void -
Removes each element of
elements
from this set.inherited -
removeListener(
VoidCallback listener) → void -

notified when the object changes.
inherited
-
removeWhere(
bool test(T element)) → void -

test
.inherited -
singleWhere(
bool test(T value), {T orElse()?}) → T -
The single element that satisfies
test
.inherited -
skip(
int n) → Iterable< T> -
