Map<K, V>.from constructor Null safety

Map<K, V>.from(
  1. Map other

Creates a LinkedHashMap instance 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.

A LinkedHashMap requires the keys to implement compatible operator== and hashCode, and it allows null as a key. It iterates in key insertion order.


factory Map.from(Map other) = LinkedHashMap<K, V>.from;
