Properties
- hashCode → int
-
The hash code for this object.
no setterinherited
- hasListeners → bool
-
Whether any listeners are currently registered.
no setterinherited
- index → int?
-
index would be the index of action items of SlideActionPanel.actions,
whatever the ActionPosition of SlideActionPanel is
no setter
- progress → double
-
the current progress of the animation during expanding or collapsing,
it indicates the index item is expanding if the progress is increasing from 0 to 1,
it indicates the index item is collapsing if the progress is decreasing from 1 to 0,
no setter
- runtimeType → Type
-
A representation of the runtime type of the object.

Methods
-
addListener(
VoidCallback listener) → void -
Register a closure to be called when the object changes.
inherited
-
collapse(
int index, {Curve curve = Curves.easeInOut, Duration duration = const Duration(milliseconds: 150)}) → Future< void> -
collapse the
index
item to the original position -
createTicker(
TickerCallback onTick) → Ticker -
Creates a ticker with the given callback.
override
-
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).
override
-
expand(
int index, {Curve curve = Curves.easeInOut, Duration duration = const Duration(milliseconds: 150)}) → Future< void> -
expand the
index
item to occupy the entire SlideActionPanel -
hasExpandedAt(
int index) → bool -
whether the
index
item is expanded -
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
-
reset(
) → void - reset the controller without triggering layout or paint
-
toggle(
int index, {Curve curve = Curves.easeInOut, Duration duration = const Duration(milliseconds: 150)}) → Future< void> -
toggle the
index
item between expanding and collapsing -
toString(
) → String -
A string representation of this object.

Operators
-
operator ==(
Object other) → bool -
