# HashMap<K, V>.fromEntries constructor Null safety

1. @Since("2.1")

HashMap<K, V>.fromEntries(

1. Iterable<MapEntry<K, V>> entries

)

Creates a HashMap containing the entries of `entries`.

Returns a new `HashMap<K, V>` where all entries of `entries` have been added in iteration order.

If multiple `entries` have the same key, later occurrences overwrite the earlier ones.

## Implementation

    @Since("2.1")
    factory HashMap.fromEntries(Iterable<MapEntry<K, V>> entries) =>
        HashMap<K, V>()..addEntries(entries);
