Then the elements with the same key are all folded using [combine]. The first call to [combine] for a particular key receives `null` as the previous value, the remaining ones receive the result of the previous call. Can be used to _group_ elements into arbitrary collections. For example [groupSetsBy] could be written as: ```dart iterable.groupFoldBy(keyOf, (Set&lt;T&gt;? previous, T element) =&gt; (previous ?? &lt;T&gt;{})..add(element)); ````" />
