Map<K, V> constructor

Map<K, V>()

Creates a Map instance with the default implementation, LinkedHashMap.

This constructor is equivalent to the non-const map literal <K,V>{}.

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

external factory Map();
