Constructors
Properties
- controller → AutoScrollController
-
final
-
controllerIsOpen
↔ StreamController<
String> -
getter/setter pair
- hashCode → int
-
The hash code for this object.
no setterinherited
- hasListeners → bool
-
no setterinherited
- initialized → bool
-
Checks whether the controller has already been initialized.
no setterinherited
- initialOpeningSequenceDelay ↔ int
-
The delay in milliseconds (when the entire accordion loads)
before the individual sections open one after another.
Helpful if you go to a new page in your app and then (after
the delay) have a nice opening sequence.
getter/setter pair
- isClosed → bool
-
Checks whether the controller has already been closed.
no setterinherited
-
keys
→ List<
UniqueKey> -
final
- listeners → int
-
no setterinherited
- maxOpenSections ↔ int
-
Maximum number of open sections at any given time.
Opening a new section will close the "oldest" open section
getter/setter pair
-
onDelete
→ InternalFinalCallback<
void> -
Internal callback that starts the cycle of this controller.
finalinherited
-
onStart
→ InternalFinalCallback<
void> -
Called at the exact moment the widget is allocated in memory.
It uses an internal "callable" type, to avoid any @overrides in subclases.
This method should be internal and is required to define the
lifetime cycle of the subclass.

openSections
→ List<
UniqueKey> -
final
- runtimeType → Type
-
A representation of the runtime type of the object.

Methods
-
$configureLifeCycle(
) → void -
inherited
-
addListener(
GetStateUpdate listener) → Disposer -
Register a closure to be called when the object notifies its listeners.
inherited
-
addListenerId(
Object? key, GetStateUpdate listener) → Disposer -
inherited
-
dispose(
) → void -
inherited
-
disposeId(
Object id) → void -
To dispose an
id
from future updates(), this ids are registered byGetBuilder()
or similar, so is a way to unlink the state change with the Widget from the Controller.inherited -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
notifyChildrens(
) → void -
inherited
-
onClose(
) → void -
Called before onDelete method. onClose might be used to
dispose resources used by the controller. Like closing events,
or streams before the controller is destroyed.
Or dispose objects that can potentially create some memory leaks,
like TextEditingControllers, AnimationControllers.
Might be useful as well to persist some data on disk.
override
-
onInit(
) → void -
Called immediately after the widget is allocated in memory.
You might use this to initialize something for the controller.
inherited
-
onReady(
) → void -
Called 1 frame after onInit(). It is the perfect place to enter
navigation events, like snackbar, dialogs, or a new route, or
async request.
inherited
-
refresh(
) → void -
inherited
-
refreshGroup(
Object id) → void -
inherited
-
removeListener(
VoidCallback listener) → void -
Remove a previously registered closure from the list of closures that the
object notifies.
inherited
-
removeListenerId(
Object id, VoidCallback listener) → void -
inherited
-
toString(
) → String -
A string representation of this object.
inherited
-
update(
[List< Object> ? ids, bool condition = true]) → void -
Rebuilds
GetBuilder
each time you callupdate()
; Can take a List ofids
, that will only update the matchingGetBuilder( id: )
,ids
can be reused amongGetBuilders
like group tags. The update will only notify the Widgets, ifcondition
is true.inherited -
updateSections(
UniqueKey key) → void - adds or removes a section key from the list of open sections and notifies sections to open or close accordingly
Operators
-
operator ==(
Object other) → bool -
The equality operator.
