MapSignal<K, V> class abstract interface

Interface for reactive map signals.

MapSignal extends Signal to provide full Map functionality while maintaining reactivity. All map operations (put, remove, clear, etc.) will trigger notifications to subscribers.

Example:

MapSignal<String, dynamic> userMap = MapSignal({'name': 'Alice', 'age': 30});

Effect(() => print('User: ${userMap['name']}'));
userMap['name'] = 'Bob'; // Triggers effect

Methods

addAll(Map<K, V> other) → void
Adds all key-value pairs from the given map to this map.
inherited
addEntries(Iterable<MapEntry<K, V>> newEntries) → void
Adds all entries from the given iterable to this map.
inherited
cast<RK, RV>() → Map<RK, RV>
Returns a view of this map as having RK keys and RV instances.
inherited
clear() → void
Removes all entries from the map.
inherited
containsKey(Object? key) → bool
Returns true if this map contains the given key.
inherited
containsValue(Object? targetValue) → bool
Returns true if this map contains the given value.
inherited
dispose() → void
Disposes this node and cleans up resources.
inherited
forEach(void action(K key, V value)) → void
Applies the given function to each key-value pair in the map.
inherited
map<K2, V2>(MapEntry<K2, V2> convert(K key, V value)) → Map<K2, V2>
Returns a new map where each entry is transformed by the given function.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notify([bool force]) → void
Triggers a change notification without modifying the value.
inherited
putIfAbsent(K key, V ifAbsent()) → V
Look up the value of key, or add a new entry if it isn't there.
inherited
remove(Object? key) → V?
Removes the entry for the given key and returns its value.
inherited
removeWhere(bool test(K key, V value)) → void
Removes all entries that satisfy the given test.
inherited
toString() → String

inherited
update(K key, V update(V value), {V ifAbsent()?}) → V
Updates the value for the given key.
inherited
updateAll(V update(K key, V value)) → void
Updates all values in the map.
inherited

Operators

operator ==(Object other) → bool
The equality operator.
inherited
operator [](Object? key) → V?

inherited
operator []=(K key, V value) → void
