IMap<K, V>.fromValues constructor
IMap<K, V>.fromValues ({})
Create an IMap from the given values
.
The keys will be the result of applying keyMapper
to the values
.
If a key
repeats, later occurrences overwrite the earlier ones.
// Results in {3: "Jim", 5: "David"}
IMap<int, String> imap = IMap.fromValues(
(String name) => name.length, ["Jim", "David"]);
Implementation
factory IMap.fromValues({
required K Function(V) keyMapper,
required Iterable<V> values,
ConfigMap? config,
}) {
config ??= defaultConfig;
Map<K, V> map = ListMap.fromEntries(
values.map((value) => MapEntry(keyMapper(value), value)),
sort: config.sort,
);
return IMap._(map, config: config);
