CurrentMapProperty<K, V> class

An CurrentProperty with similar characteristics as a dart Map<K, V>

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

Properties

entries → Iterable<MapEntry<K, V>>
The map entries in the map
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 there is no key/value pair in the map.
no setter
isNotEmpty → bool
Whether there is at least one key/value pair in the map.
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

keys → Iterable<K>
The keys of the map.
no setter
length → int
The number of key/value pairs in the map.
no setter
originalValue → Map<K, V>
no setterinherited
propertyName ↔ String?
getter/setter pairinherited
registeredBindings → Iterable<CurrentViewModelBinding>
Helper bindings registered directly against this property.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
sourceHashCode → int

value ↔ Map<K, V>
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.

values → Iterable<V>
The values of the map.
no setter
viewModel → CurrentStateViewModel
Returns the instance of the CurrentStateViewModel this property is associated with.

Methods

add(K key, V value, {bool notifyChanges = true}) → void
If the key is already in this map, the corresponding value is overwritten.
addAll(Map<K, V> other, {bool notifyChanges = true, bool capturePrevious = false}) → void
Adds all key/value pairs of other to this map.
addEntries(Iterable<MapEntry<K, V>> entries, {bool notifyChanges = true, bool capturePrevious = false}) → void
Adds all key/value pairs of entries to this map.
addEntry(MapEntry<K, V> entry, {bool notifyChanges = true}) → void
Adds the key/value pair to this map.
call(Map<K, V> 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 entries from the map.
containsKey(K key) → bool
Whether this map contains the given key.
containsValue(V value) → bool
Whether this map contains the given value.
equals(dynamic other) → bool
Checks if other is equal to the value of this CurrentProperty.
inherited
forEach(void action(dynamic, dynamic)) → void
Applies action to each key/value pair of the map.
hasValueChanged(Map<K, V> currentValue, Map<K, V> originalValue) → bool
Determines whether the current value differs from the original value.
override
map<K2, V2>(MapEntry<K2, V2> convert(dynamic, dynamic)) → Map<K2, V2>
Returns a new map where all entries of this map are transformed by the given convert function.
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(K key, {bool notifyChanges = true}) → V?
Removes key and its associated value, if present, from the map.
removeWhere(bool test(K key, V value), {bool notifyChanges = true}) → void
Removes all entries of this map that satisfy the given test.
reset({bool notifyChange = true}) → void
Resets the value to the originalValue.
override
set(Map<K, V> value, {bool notifyChange = true, bool setAsOriginal = false}) → Map<K, V>
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
toString() → String
A string representation of this object.
inherited
update(K key, V update(V value), {V ifAbsent()?, bool notifyChanges = true}) → V
Updates the value for the provided key.
updateAll(V update(K key, V value), {bool notifyChanges = true}) → void
