Methods

addAll(Map<String, Knob> other) → void: Adds all key/value pairs of other to this map.
inherited
addEntries(Iterable<MapEntry<String, Knob>> 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.
override
containsKey(Object? key) → bool: Whether this map contains the given key.
inherited
containsValue(Object? value) → bool: Whether this map contains the given value.
inherited
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 will throw after the object is disposed).
inherited
forEach(void action(String key, Knob value)) → void: Applies action to each key/value pair of the map.
inherited
lock() → void
map<K2, V2>(MapEntry<K2, V2> transform(String key, Knob 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, Knob ifAbsent()) → Knob: Look up the value of key, or add a new entry if it isn't there.
inherited
register<T>(Knob<T?> knob, Map<String, String> queryGroup) → T?
remove(Object? key) → Knob?: 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(String key, Knob value)) → void: Removes all entries of this map that satisfy the given test.
inherited
toString() → String: A string representation of this object.
inherited
update(String key, Knob update(Knob value), {Knob ifAbsent()?}) → Knob: Updates the value for the provided key.
inherited
updateAll(Knob update(String key, Knob value)) → void: Updates all values.
inherited
updateNullability(String label, bool isNull) → void: Updates Knob.isNull using the label to find the Knob.
updateValue<T>(String label, T value) → void

Operators

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