NotifiableMap<K, V> class

Class that mimics Map, and notify its listener every time the map is changed.

This map will notify its listener when a change is detected (an entry has been added, removed, updated, etc... or the map has been sorted, mapped, etc...). However, it won't notify its listener if its items are changed, even if they extends ChangeNotifier.

Constructors

NotifiableMap()

Create an empty NotifiableMap.

NotifiableMap.from(Map<K, V> other)

Create a NotifiableMap by adding all elements from other, regardless of their type.

NotifiableMap.of(Map<K, V> other)

Create a NotifiableMap by adding all elements of other of types K, V.

Properties

entries → Iterable<MapEntry<K, V>>

The map entries of this Map.

no setter, override

hashCode → int

The hash code for this object.

no setter, override

hasListeners → bool

Whether any listeners are currently registered.

no setter, inherited

isEmpty → bool

Whether there is no key/value pair in the map.

no setter, override

isNotEmpty → bool

Whether there is at least one key/value pair in the map.

no setter, override

keys → Iterable<K>

The keys of this Map.

no setter, override

length → int

The number of key/value pairs in the map.

no setter, override

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

values → Iterable<V>

The values of this Map.

no setter, override

Methods

addAll(Map<K, V> other) → void

Adds all key/value pairs of other to this map.

override

addEntries(Iterable<MapEntry<K, V>> newEntries) → void

Adds all key/value pairs of newEntries to this map.

override

addListener(VoidCallback listener) → void

Register a closure to be called when the object changes.

inherited

cast<RK, RV>() → Map<RK, RV>

Provides a view of this map as having RK keys and RV instances, if necessary.

override

clear() → void

Removes all entries from the map.

override

containsKey(Object? key) → bool

Whether this map contains the given key.

override

containsValue(Object? value) → bool

Whether this map contains the given value.

override

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

forEach(void f(K key, V value)) → void

Applies action to each key/value pair of the map.

override

map<RK, RV>(MapEntry<RK, RV> f(K key, V value)) → Map<RK, RV>

Returns a new map where all entries of this map are transformed by the given convert function.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

notifyListeners() → void

Call all the registered listeners.

inherited

putIfAbsent(K key, V ifAbsent()) → V

Look up the value of key, or add a new entry if it isn't there.

override

remove(Object? key) → V?

Removes key and its associated value, if present, from the map.

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 predicate(K key, V value)) → void

Removes all entries of this map that satisfy the given test.

override

toString() → String

A string representation of this object.

inherited

update(K key, V update(V value), {V ifAbsent()?}) → V

Updates the value for the provided key.

override

updateAll(V update(K key, V value)) → void

Updates all values.

override

Operators

operator +(NotifiableMap<K, V> other) → NotifiableMap<K, V>

Creates a new NotifiableMap that contains the entries of this map and the elements of other in that order.

operator ==(Object other) → bool

The equality operator.

override

operator [](Object? key) → V?

The value for the given key, or null if key is not in the map.

override

operator []=(K key, V value) → void

Associates the key with the given value.
