ActiveList<T> class

An ActiveList with similar characteristics as a an ordinary dart List object. When an update is done an ActiveStateChanged event is triggered which in-turn makes a UI rebuild of that widget.

Has similar characteristics as int and The value cannot be null

Methods

add(T value, {bool notifyActivities = true}) → void
Adds value to the end of this list, extending the length by one.
addAll(Iterable<T> values, {bool notifyActivities = true}) → void
Appends all objects of values to the end of the list.
call(List<T> value, {bool notifyChange = true, bool setAsOriginal = false}) → void
Updates the underlying value for this ActiveType.
inherited
clear({bool notifyActivities = true}) → void
Removes all objects from this list; the length of the list becomes zero.
contains(T value) → bool
Whether the collection contains an element equal to value.
elementAt(int index) → T
Returns the indexth element.
equals(dynamic other) → bool
Checks if other is equal to the value of this ActiveType
inherited
firstWhere(bool test(T element), {T orElse()?}) → T
Returns the first element that satisfies the given predicate test.
firstWhereOrNull(bool test(T element)) → T?
Returns the first element that satisfies the given predicate test.
forEach(void action(T)) → void
Invokes action on each element of this iterable in iteration order.
indexOf(T value, [int start = 0]) → int
The first index of value in this list.
indexWhere(bool test(T element), [int start = 0]) → int
The first index in the list that satisfies the provided test.
map<E>(E toElement(T)) → Iterable<E>
The current elements of this iterable modified by toElement.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
remove(T value, {bool notifyActivities = true}) → bool
Removes the first occurrence of value from this list.
removeAt(int index, {bool notifyActivities = true}) → T
Removes the object at position index from the list.
reset({bool notifyChange = true}) → void
Resets the value to the originalValue.
inherited
set(List<T> value, {bool notifyChange = true, bool setAsOriginal = false}) → List<T>
Updates the property value. Notifies any listeners to the change
inherited
setActiveController(ActiveController activeController) → void
Links this ActiveType instance with an ActiveController.
inherited
setOriginalValueToCurrent() → void
Updates the original value to what the current value of this property is.
inherited
toString() → String
A string representation of this object.
inherited
where(bool test(T element)) → List<T>
Returns a new List with all elements that satisfy the predicate test.

Operators

operator ==(dynamic other) → bool
The equality operator.
inherited
operator [](int index) → T
The object at the given index in the list.
