IndexMap<K extends dynamic, V>.fromMap constructor

IndexMap<K extends dynamic, V>.fromMap(
  1. List<K> keys,
  2. Map<K, V> map
)

Implementation

IndexMap.fromMap(List<K> keys, Map<K, V> map)
  : assert(keys.every((key) => map.containsKey(key) || null is V)),
    _keysReference = keys,
    _valuesBuffer = List.from(keys.map((key) => map[key] as V), growable: false);
