Methods

addAll(Map<K, V> other) → void
Throws an UnsupportedError; operations that change the map are disallowed.
override
addEntries(Iterable<MapEntry<K, V>> newEntries) → void
Adds all key/value pairs of newEntries to this map.
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
Throws an UnsupportedError; operations that change the map are disallowed.
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
filterByExcludedKeys(List<K> excludedKeys) Map<K, V>

Available on Map<K, V>, provided by the MapWithDefaultOnMapX extension

Filters the map's entries based on a list of excluded keys. Returns a new map excluding the key-value pairs where the key is found within the excludedKeys.
filterByExcludedValues(List<V> excludedValues) Map<K, V>

Available on Map<K, V>, provided by the MapWithDefaultOnMapX extension

Filters the map's entries based on a list of excluded values. Returns a new map excluding the key-value pairs where the value is found within the excludedValues.
filterByIncludedKeys(List<K> includedKeys) Map<K, V>

Available on Map<K, V>, provided by the MapWithDefaultOnMapX extension

Filters the map's entries based on a list of included keys. Returns a new map containing only the key-value pairs where the key is found within the includedKeys.
filterByIncludedValues(List<V> includedValues) Map<K, V>

Available on Map<K, V>, provided by the MapWithDefaultOnMapX extension

Filters the map's entries based on a list of included values. Returns a new map containing only the key-value pairs where the value is found within the includedValues.
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
mapKeys<K2>(K2 mapper(K1 key)) Map<K2, V1>

Available on Map<K1, V1>, provided by the MapKeysAndValyesOnMapX extension

Returns a new map with new keys and the same values.
mapValues<V2>(V2 mapper(V1 value)) Map<K1, V2>

Available on Map<K1, V1>, provided by the MapKeysAndValyesOnMapX extension

Returns a new map with the same keys and new values.
mapWithDefault(dynamic defaultValue) Map<K, dynamic>

Available on Map<K, V>, provided by the MapWithDefaultOnMapX extension

Returns a new map with the same keys as this map but with the specified defaultValue for all values that are null. If defaultValue is null, it simply returns a copy of the original map.
maybeAdd(Map<T1, T2>? add) Map<T1, T2>

Available on Map<T1, T2>, provided by the MaybeAddToMapX extension

Adds add to this its not null.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
putIfAbsent(K key, V ifAbsent()) → V
Throws an UnsupportedError; operations that change the map are disallowed.
override
remove(Object? key) → V
Throws an UnsupportedError; operations that change the map are disallowed.
override
removeWhere(bool test(K key, V value)) → void
Removes all entries of this map that satisfy the given test.
inherited
setNestedValue(List keyPath, dynamic value) → void

Available on Map, provided by the SetNestedValueOnMapX extension
