Methods

inverse() → Map<V, List<K>>

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

Inverts this map with keys becoming values and vice versa.

putAll(Map<K, V> other, {required V resolve(K key, V existing, V other)}) → void

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

Adds all entries in other to this map, using resolve to resolve conflicting entries.

rekey<K1>(K1 convert(K key)) → Map<K1, V>

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

Returns a copy of this map with its keys transformed using convert.

retainWhere(bool predicate(K key, V value)) → void

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

Retains all entries that satisfy the given predicate.

revalue<V1>(V1 convert(V value)) → Map<K, V1>

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

Returns a copy of this map with its values transformed using convert.

where(bool predicate(K key, V value)) → Map<K, V>

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

Eagerly returns a map with only entries that satisfy the given predicate.

Static Methods

merge<K, V>(Map<K, V> a, Map<K, V> b, {required V resolve(K key, V a, V b)}) → Map<K, V>

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

Merges a and b, using resolve to resolve conflicting entries.
