Constructors
-
ListValueNotifier(List<
T> rawList) -
Creates a ListValueNotifier that wraps this value
_rawList.
Properties
- hashCode → int
-
The hash code for this object.
no setterinherited
- hasListeners → bool
-
Whether any listeners are currently registered.
no setterinherited
- last ← T
-
no getter
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
-
value
→ List<
T> -
The current value of the object. When the value changes, the callbacks
registered with addListener will be invoked.

Methods
-
add(
T element) → void - Adds an element to the list and notifies listeners.
-
addAll(
Iterable< T> elements) → void - Adds elements to the list and notifies listeners.
-
addListener(
VoidCallback listener) → void -
Register a closure to be called when the object changes.
inherited
-
clear(
) → void - Clears the list and notifies listeners.
-
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.
override
-
remove(
T value) → bool -
Removes the first occurrence of
valuefrom this list. -
removeAll(
Iterable< T> elements) → void -
removeAt(
int index) → void -
Removes the object at position
indexfrom this list. -
removeListener(
VoidCallback listener) → void -
Remove a previously registered closure from the list of closures that are
notified when the object changes.
inherited
-
removeRange(
int start, int end) → void - Removes a range of elements from the list.
-
replace(
T existing, T replacement) → bool - Replaces the first occurrence of value in this list.
-
replaceAll(
Iterable< T> elements) → void - Replaces all elements in the list and notifies listeners. It's preferred to calling .clear() then .addAll(), because it only notifies listeners once.
-
toString(
) → String -
A string representation of this object.
inherited
-
trimToSublist(
int start, [int? end]) → void -
Truncates to just the elements between
startandend.
Operators
-
operator ==(
Object other) → bool -
The equality operator.
