NumWatcher class - flutter_watcher library

Constructors

NumWatcher(num initial)

Properties

hashCode → int: The hash code for this object.
no setterinherited
hasListeners → bool: Whether any listeners are currently registered.
no setterinherited
isDisposed → bool: Flag which returns true if you called the dispose method. It is useful when you want to safely do some operations on the Watcher without getting an exception if it gets disposed.
no setterinherited
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
safeMode → bool: safeMode if enabled will not allow any setting of value or notifying any listeners if the Watcher isDisposed
finalinherited
stream → Stream<num>: Converts the Watcher into a Stream. This stream emits values whenever the value changes. The use of distinct ensures that consecutive duplicate values are filtered out, thus the stream only emits when the value actually changes.
no setterinherited
v ↔ num: Equivalent to the getter value but in shorter syntax.
getter/setter pairinherited
value ↔ num: The current value stored in this watcher.
getter/setter pairinherited

Methods

addListener(VoidCallback listener) → void: Register a closure to be called when the object changes.
inherited
debounce(Duration duration, void action(num value)) → VoidCallback: Registers a debounced callback which is invoked only after the notifier's value is stable for the specified duration.
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
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void: Call all the registered listeners.
inherited
onChange(void action(num value)) → VoidCallback: Registers a callback to be invoked whenever the ValueNotifier's value changes.
inherited
refresh() → void: Rebuilds and trigger any listeners of any WatchValue or watch attached to that Watcher.
inherited
removeListener(VoidCallback listener) → void: Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
setWithoutNotify(num newValue) → void: inherited
toString() → String: A string representation of this object.
inherited
updateIf(bool condition(num), num newValue) → void: Updates the ValueNotifier's value to newValue if condition returns true.
inherited
updateOnAction<R>(R action()) → R: Will notifyListeners after a specific action has been made, and optionally return a result R of certain type.
