Map.from factory constructor

Map.from(Map other)

Creates a LinkedHashMap instance that contains all key-value pairs of other.

The keys must all be assignable to K and the values to 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.
