Methods

addAll(Map<K, V> other) → void
This operation is not supported by an unmodifiable map.
override
addEntries(Iterable<MapEntry<K, V>> entries) → void
This operation is not supported by an unmodifiable map.
override
cast<RK, RV>() → Map<RK, RV>
Provides a view of this map as having RK keys and RV instances, if necessary.
inherited
clear() → void
This operation is not supported by an unmodifiable 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
forEach(void action(K key, V value)) → void
Applies action to each key/value pair of the map.
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.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
putIfAbsent(K key, Callback<V> ifAbsent) → V
This operation is not supported by an unmodifiable map.
override
remove(Object? key) → V?
This operation is not supported by an unmodifiable map.
override
removeWhere(Value2Callback<K, V, bool> test) → void
This operation is not supported by an unmodifiable map.
override
toString() → String
A string representation of this object.
inherited
update(K key, Value1Callback<V, V> update, {Callback<V>? ifAbsent}) → V
This operation is not supported by an unmodifiable map.
override
updateAll(Value2Callback<K, V, V> update) → void
This operation is not supported by an unmodifiable map.
override

Operators

operator ==(Object other) → bool
The equality operator.
inherited
operator [](Object? key) → V?
The value for the given key, or null if key is not in the map.
inherited
operator []=(K key, V value) → void
This operation is not supported by an unmodifiable map.
