addEntries method

  1. @override
void addEntries (Iterable<MapEntry<K, V>> entries)
override

Adds all key/value pairs of newEntries to this map.

If a key of newEntries is already in this map, the corresponding value is overwritten.

The operation is equivalent to doing this[entry.key] = entry.value for each MapEntry of the iterable.

Implementation 

@override
void addEntries(Iterable<MapEntry<K, V>> entries) =>
    entries.forEach((entry) => this[entry.key] = entry.value);
