Methods

cancel(ControlSubscription<T> subscription) → void

override

cast<U>() → ObservableValue<U>

inherited

clear() → void

createSubscription([dynamic args]) → ControlSubscription<T>

dispose() → void

Used to clear and dispose object. After this method call is object typically unusable and ready for GC. Can be called multiple times!

override

disposeWith(DisposeObserver observer) → void

Available on Disposable, provided by the DisposableExt extension

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

notify() → void

override

pause() → void

resume() → void

setFalse() → void

Available on ObservableModel<bool>, provided by the ObservableBoolExt extension

Sets value to 'false'. Listeners are notified if value is changed.

setTrue() → void

Available on ObservableModel<bool>, provided by the ObservableBoolExt extension

Sets value to 'true'. Listeners are notified if value is changed.

setValue(T value, {bool notify = true, bool forceNotify = false}) → void

override

subscribe(ValueCallback<T> action, {bool current = true, dynamic args}) → ControlSubscription<T>

override

toggle() → bool

Available on ObservableModel<bool>, provided by the ObservableBoolExt extension

Toggles current value and notifies listeners. 'true' -> 'false' 'false' -> 'true'

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
