- Map other
Creates a HashMap that contains all key/value pairs of other.
The keys must all be instances of K and the values of V.
The other map itself can have any type.
Implementation
factory HashMap.from(Map<dynamic, dynamic> other) {
HashMap<K, V> result = HashMap<K, V>();
other.forEach((dynamic k, dynamic v) {
result[k as K] = v as V;
});
return result;
}
