MapModelMixin<K, V> mixin
A mix-in that allows you to use a model as a map.
It can be applied to any ValueModel that has a Map<K, V>.

Properties
- disposed → bool
-
True if the model is Disposed.
no setterinherited
-
entries
→ Iterable<
MapEntry< K, V> > -
The map entries of this.
no setteroverride
- hashCode → int
-
The hash code for this object.
no setteroverride
- hasListeners → bool
-
Whether any listeners are currently registered.
no setterinherited
- isEmpty → bool
-
Whether there is no key/value pair in the map.
no setteroverride
- isNotEmpty → bool
-
Whether there is at least one key/value pair in the map.
no setteroverride
-
keys
→ Iterable<
K> -
The keys of this.
no setteroverride
- length → int
-
The number of key/value pairs in the map.
no setteroverride
- notifyOnChangeMap → bool
-
If this value is
true
, Notify changes when there are changes in the map itself using map-specific methods.no setter - notifyOnChangeValue → bool
-
If this value is
true
, the change will be notified when value itself is changed.no setteroverride - runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
-
value
↔ Map<
K, V> -
The current value stored in this notifier.
getter/setter pairinherited
-
values
→ Iterable<
V> -
The values of this.

Methods
-
addAll(
Map< K, V> other) → void -
Adds all key/value pairs of
other
to this map.override -
addEntries(
Iterable< MapEntry< newEntries) → voidK, V> > -
Adds all key/value pairs of
newEntries
to this map.override -
addListener(
VoidCallback listener) → void -
Register a closure to be called when the object changes.
inherited
-
cast<
RK, RV> () → Map< RK, RV> -
Provides a view of this map as having
RK
keys andRV
instances, if necessary.override -
clear(
) → void -
Removes all entries from the map.
override
-
containsKey(
Object? key) → bool -
Whether this map contains the given
key
.override -
containsValue(
Object? value) → bool -
Whether this map contains the given
value
.override -
dependOn(
Listenable listenable, [Map< K, V> filter(Map<K, V> origin)?]) → void -
Sends a notification to itself when the target
listenable
is updated.override -
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 and removeListener will throw after the object is
disposed).
override
-
forEach(
void action(K key, V value)) → void -
Applies
action
to each key/value pair of the map.override -
initState(
) → void -
The method to be executed when initialization is performed.
inherited
-
map<
K2, V2> (MapEntry< K2, V2> convert(K key, V value)) → 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
-
notifyListeners(
) → void -
Call all the registered listeners.
inherited
-
putIfAbsent(
K key, V ifAbsent()) → V -
Look up the value of
key
, or add a new entry if it isn't there.override -
remove(
Object? key) → V? -
Removes
key
and its associated value, if present, from the map.override -
removeListener(
VoidCallback listener) → void -
Remove a previously registered closure from the list of closures that are
notified when the object changes.
inherited
-
removeWhere(
bool test(K key, V value)) → void -
Removes all entries of this map that satisfy the given
test
.override -
toNotifier<
V> (V converter(Map< K, V> value)) → ValueNotifier<V> -
Generates a value notifier.
inherited
-
toString(
) → String -
A string representation of this object.
inherited
-
update(
K key, V update(V value), {V ifAbsent()?}) → V -
Updates the value for the provided
key
.override -
updateAll(
V update(K key, V value)) → void -
Updates all values.
override
Operators
-
operator ==(
Object other) → bool -
The equality operator.
override
-
operator [](
Object? key) → V? -
The value for the given
key
, or null ifkey
is not in the map.override -
operator []=(
K key, V value) → void -
Associates the
key
with the givenvalue
