MapModel([Map<String, T>? map])
A model that can be treated as a map.

Properties

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

Methods

addAll(Map<String, T> other) → void
Adds all key/value pairs of other to this map.
inherited
addEntries(Iterable<MapEntry<String, T>> newEntries) → void
Adds all key/value pairs of newEntries to this map.
inherited
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 and RV instances, if necessary.
inherited
clear() → void
Removes all entries from the map.
inherited
containsKey(Object? key) → bool
Whether this map contains the given key.
inherited
containsValue(Object? value) → bool
Whether this map contains the given value.
inherited
dependOn(Listenable listenable, [Map<String, T> filter(Map<String, T> 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).
inherited
forEach(void action(String key, T value)) → void
Applies action to each key/value pair of the map.
inherited
initState() → void
The method to be executed when initialization is performed.
inherited
map<K2, V2>(MapEntry<K2, V2> convert(String key, T value)) → Map<K2, V2>
Returns a new map where all entries of this map are transformed by the given convert function.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void
Call all the registered listeners.
inherited
putIfAbsent(String key, T ifAbsent()) → T
Look up the value of key, or add a new entry if it isn't there.
inherited
remove(Object? key) → T?
Removes key and its associated value, if present, from the map.
inherited
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(String key, T value)) → void
Removes all entries of this map that satisfy the given test.
inherited
toNotifier<V>(V converter(Map<String, T> value)) → ValueNotifier<V>
Generates a value notifier.
inherited
toString() → String
A string representation of this object.
inherited
update(String key, T update(T value), {T ifAbsent()?}) → T
Updates the value for the provided key.
inherited
updateAll(T update(String key, T value)) → void
Updates all values.
inherited

Operators

operator ==(Object other) → bool
The equality operator.
inherited
operator [](Object? key) → T?
The value for the given key, or null if key is not in the map.
inherited
operator []=(String key, T value) → void
Associates the key with the given value.
