addEntries method
Adds all the key/value pairs of newEntries
to othis map.
Listeners are notified after all the entries have been added.
If a key of newEntries
is already in the map,
the corresponding value is ovewritten.
The operations is equivalent to doing this[entry.key] = entry.value
for each MapEntry of the iterable.
Implementation
@override
void addEntries(Iterable<MapEntry<K, T>> newEntries) {
assert(_debugAssertNotDisposed());
_map!.addEntries(newEntries);
notifyListeners();
}
