NotifiableMap<K, V> class Null safety

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.

Inheritance

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.
read-only
hashCode → int
The hash code for this object. [...]
read-only
hasListeners → bool
Whether any listeners are currently registered. [...]
@protected, read-only, inherited
isEmpty → bool
Whether there is no key/value pair in the map.
read-only
isNotEmpty → bool
Whether there is at least one key/value pair in the map.
read-only
keys → Iterable<K>
The keys of this. [...]
read-only
length → int
The number of key/value pairs in the map.
read-only
runtimeType → Type
A representation of the runtime type of the object.
read-only, inherited
values → Iterable<V>
The values of this. [...]
read-only

Methods

addAll(Map<K, V> other) → void
Adds all key/value pairs of other to this map. [...]
addEntries(Iterable<MapEntry<K, V>> newEntries) → void
Adds all key/value pairs of newEntries to this map. [...]
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. [...]
clear() → void
Removes all entries from the map. [...]
containsKey(Object? key) → bool
Whether this map contains the given key. [...]
containsValue(Object? value) → bool
Whether this map contains the given value. [...]
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 and removeListener will throw after the object is disposed). [...]
@mustCallSuper, inherited
forEach(void f(K key, V value)) → void
Applies action to each key/value pair of the map. [...]
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.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
inherited
notifyListeners() → void
Call all the registered listeners. [...]
@protected, @visibleForTesting, inherited
putIfAbsent(K key, V ifAbsent()) → V
Look up the value of key, or add a new entry if it isn't there. [...]
remove(Object? key) → V?
Removes key and its associated value, if present, from the map. [...]
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.
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. [...]
updateAll(V update(K key, V value)) → void
Updates all values. [...]

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. [...]
operator [](Object? key) → V?
The value for the given key, or null if key is not in the map. [...]
operator []=(K key, V value) → void
Associates the key with the given value. [...]
