containsValue(Object value) bool

Returns true if this map contains the given value.

forEach(void action(K key, V value)) → void

Applies f to each key-value pair of the map.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a non-existent method or property is accessed.

inherited
putIfAbsent(K key, V ifAbsent()) → V
