Constructors

Signal(): Creates a EnhancedValueNotifier that wraps boolean value, True in default.

hashCode → int: The hash code for this object.
no setterinherited
hasListeners → bool: Override hasListeners to check if there are any listeners.
no setterinherited
properties → Map<String, dynamic>: A notifying map view for reading and writing property values by name.
no setterinherited
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
value ↔ bool: The current value stored in this notifier.

addListener(Function listener, {Object? target, bool once = false, bool immediate = false}) → void: Register a listener for a specific property target can be an element or elements list like [ property1, property2 ]
inherited
dispose() → void: Override dispose to 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
fromMap(Map<String, dynamic> props) → void: Initializes stored values from props without notifying listeners.
inherited
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners([String? target]) → void: Notify listeners for a specific element
inherited
promise(VoidCallback listener) → void: register a listener in promise's prototype consumed immediately or awaited once via Signal(True).
removeListener(Function listener) → void: Remove a listener
inherited
toString() → String: Returns a debug description containing this object's identity and value.

operator ==(Object other) → bool: The equality operator.
inherited
operator [](String target) → dynamic: Returns the stored value for target.
inherited
operator []=(String target, dynamic value) → void: Stores value for target and notifies listeners for target.
