Constructors

ChoiceController.new({List<T> value = const [], List<T> items = const [], ValueChanged<List<T>>? onChanged, bool multiple = false, bool mandatory = false})

hashCode → int: The hash code for this object.
no setterinherited
hasListeners → bool: Whether any listeners are currently registered.
no setterinherited
isChecked → bool: no setter
isEmpty → bool: no setter
isIndeterminate → bool: no setter
isNotEmpty → bool: no setter
items → List<T>: final
length → int: no setter
mandatory → bool: will always have a value
final
multiple → bool: allow to select multiple values
final
onChanged → ValueChanged<List<T>>?: final
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
value → List<T>: no setter

add(T item) → void: Mutator to mark a T value as active.
addListener(VoidCallback listener) → void: Register a closure to be called when the object changes.
inherited
clear() → void
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
fill() → void
has(T value) → bool
hasAny(List<T> value) → bool
hasEvery(List<T> value) → bool
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void: Call all the registered listeners.
inherited
remove(T item) → void: Mutator to mark a T value as inactive.
removeListener(VoidCallback listener) → void: Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
replace(List<T> value) → void
select(T item, {ValueChanged<bool>? onChanged}) → ValueChanged<bool>
selectAll({ValueChanged<bool>? onChanged}) → ValueChanged<bool>
toggle(T item, [bool? active]) → void: Mutator to mark a T value as either active or inactive.
toString() → String: A string representation of this object.
