# Map<K, V>.from constructor

Map<K, V>.from(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.

## Implementation

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