no setterinherited
hasListeners bool

Methods

addListener(VoidCallback listener) → void
Register a closure to be called when the object changes.
inherited
disableRefresh() → void
Disables list pull to refresh
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
enableRefresh() → void
Enables list pull to refresh
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
setAxisDirection(AxisDirection direction) → void
Sets the direction in which list scrolls
setIndicatorEdge(IndicatorEdge? edge) → void
setIndicatorState(IndicatorState newState) → void
sets indicator state and notifies listeners
setScrollingDirection(ScrollDirection userScrollDirection) → void
setValue(double value) → void
stopDrag() → void
toString() String
A string representation of this object.
