Map.identity constructor - Map - dart:core library (original) (raw)

description

Map<K, V>.identity()

Creates an identity map with the default implementation, LinkedHashMap.

An identity map uses identical for equality and identityHashCodefor hash codes of keys instead of the intrinsic Object.== andObject.hashCode of the keys.

The map iterates in key insertion order.

Implementation

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