ObservableList<T> class
Class that represents our list-type observable
- Inheritance
-
- Object
- ChangeNotifier
- ObservableValue<
List< T> > - ObservableList
- Available Extensions
Constructors
-
ObservableList({required List<
T> value}) - Constructor to init ObservableValue with value
Properties
- first → T
-
get first item
no setter
- hashCode → int
-
The hash code for this object.
no setterinherited
- hasListeners → bool
-
Whether any listeners are currently registered.
no setterinherited
- isEmpty → bool
-
get if list is empty
no setter
- isNotEmpty → bool
-
get if list is not empty
no setter
- last → T
-
get last item
no setter
-
lastValue
→ List<
T> ? -
Get las value of the observable
no setterinherited
- length → int
-
get size list
no setter
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
-
setValueWithoutNotify
← List<
T> -
Method uses to set value without notify listeners
no getterinherited
-
value
↔ List<
T> -
Get current value of the observable
getter/setter pairinherited
Methods
-
add(
T value) → void - add element in list and notify listeners
-
addAll(
Iterable< T> value) → void - add element list in list and notify listeners
-
addListener(
VoidCallback listener) → void -
Register a closure to be called when the object changes.
inherited
-
clear(
) → void - clear list and notify 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
-
indexOf(
T element) → int - use List.indexOf
-
indexWhere(
bool test(T element), [int start = 0]) → int - use List.indexWhere
-
insert(
int index, T element) → void - insert element in the index
-
insertAll(
int index, Iterable< T> iterable) → void - insert element list in the index
-
modify(
ModifyValue< List< modify) → voidT> > -
user do modify value. recommended return new instance
(use copyWith if is possible).
inherited
-
modifyItem(
int index, T modify(T value)) → void - use to modify specific item in the list
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
notifyListeners(
) → void -
Call all the registered listeners.
inherited
-
remove(
T value) → void - remove in list and notify listeners
-
removeAt(
int index) → void - remove element by index in list and notify listeners
-
removeLast(
) → void - remove last element in list and notify listeners
-
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 - remove element by range in list and notify listeners
-
removeWhere(
bool test(T element)) → void - remove element in list and notify listeners
-
replaceRange(
int start, int end, Iterable< T> replacement) → void - replace elements in list and notify listeners
-
toString(
) → String -
A string representation of this object.
inherited
-
update(
List< T> value) → void -
uses to update value
inherited
Operators
-
operator ==(
Object other) → bool -
The equality operator.
