CurrentListProperty<T> class

An CurrentProperty with similar characteristics as a dart List<T>

Any change to the internal list will send a CurrentStateChanged event by default. This includes automatically triggering a UI rebuild.

Constructors

Properties

first → T
Returns the first element.
no setter
hashCode → int
The hash code for this object.
no setterinherited
isDirty → bool
Returns true if the value of this CurrentProperty is different from the originalValue.
no setterinherited
isEmpty → bool
Whether this value has no elements.
no setter
isNotEmpty → bool
Whether this value has no elements.
no setter
isNotNull → bool
Returns true if the value of this CurrentProperty is not null.
no setterinherited
isNull → bool
Returns true if the value of this CurrentProperty is null.
no setterinherited
isPrimitiveType → bool
finalinherited
last → T
Returns the last element.
no setter
length → int
The number of objects in this list.
no setter
originalValue → List<T>
no setterinherited
propertyName ↔ String?
getter/setter pairinherited
registeredBindings → Iterable<CurrentViewModelBinding>
Helper bindings registered directly against this property.
no setterinherited
reversed → List<T>
A List of the objects in this list in reverse order.
no setter
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
single → T
Checks that this has only one element, and returns that element.
no setter
sourceHashCode → int
finalinherited
value ↔ List<T>
Returns the current value of this CurrentProperty. Setting the value will update the value of this CurrentProperty and trigger a UI update if the new value is different from the current value. If T is a reference type, setting the value to a new instance of T with the same properties as the current value will still trigger a UI update since the reference has changed.
getter/setter pairinherited
viewModel → CurrentStateViewModel
Returns the instance of the CurrentStateViewModel this property is associated with.

Methods

add(T value, {bool notifyChanges = true}) → void
Adds value to the end of this list, extending the length by one.
addAll(Iterable<T> values, {bool notifyChanges = true, bool capturePrevious = false}) → 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 CurrentProperty.
inherited
clear({bool notifyChanges = true, bool capturePrevious = false}) → 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 CurrentProperty.
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.
hasValueChanged(List<T> currentValue, List<T> originalValue) → bool
Determines whether the current value differs from the original value.
override
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.
insert(int index, T element, {bool notifyChanges = true}) → void
Inserts element at position index in this list.
insertAll(int index, Iterable<T> values, {bool notifyChanges = true, bool capturePrevious = false}) → void
Inserts all objects of values at position index in this list. This increases the length of the list by the length of values and shifts all later objects towards the end of the list. The list must be growable. The index must be a valid index in the list or length.
insertAllAtEnd(Iterable<T> values, {bool notifyChanges = true, bool capturePrevious = false}) → void
Inserts values at the end of this list This increases the length of the list by the length of values
map<E>(E toElement(T)) → Iterable<E>
The current elements of this iterable modified by toElement.
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
registerBinding(CurrentViewModelBinding binding) → void
Registers a helper binding against this property.
inherited
remove(T value, {bool notifyChanges = true}) → bool
Removes the first occurrence of value from this list.
removeAt(int index, {bool notifyChanges = true}) → T
Removes the object at position index from the list.
reset({bool notifyChange = true}) → void
Resets the value to the originalValue.
override
set(List<T> value, {bool notifyChange = true, bool setAsOriginal = false}) → List<T>
Updates the property value. Notifies any listeners to the change
inherited
setOriginalValueToCurrent() → void
Updates the original value to what the current value of this property is.
inherited
setViewModel(CurrentStateViewModel viewModel) → void
Links this CurrentProperty instance with an CurrentStateViewModel.
inherited
sublist(int start, [int? end]) → List<T>
Returns a new list containing the elements between start and end.
toString() → String
Returns the current contents of the list as a formatted String
override
where(bool test(T element)) → Iterable<T>
Returns a new lazy Iterable with all elements that satisfy the predicate test.

Operators

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