equalItems method
Will return true
only if the IMap entries are equal to the entries in
the Iterable. Order is irrelevant. This may be slow for very large maps,
since it compares each entry, one by one. To compare with a map, use
method equalItemsToMap or equalItemsToIMap.
Implementation
@override
bool equalItems(covariant Iterable<MapEntry> other) {
return (flush._m as MFlat<K, V>).deepMapEqualsToIterable(other);
}
