Methods

addListener(VoidCallback listener) → void
Register a closure to be called when the object changes.
inherited
changeValue(T begin, T end) → void
convert(double animatorPercent) → T
该方法由子类复写且只能在getValue内部调用
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
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
safeGetValue(double t) → T
start([TickerProvider? provider, bool allowRest = false]) → void
stop([bool reset = true]) → void
toString() String
A string representation of this object.
override
update(double t) → void

Operators

operator ==(Object other) bool
The equality operator.
