CombinedListView and CombinedMapView create unmodifiable views across multiple underlying collections that reflect underlying structural mutations dynamically without copying.
Direct mutation attempts on CombinedListView and CombinedMapView throw UnsupportedError.
CombinedMapView resolves duplicate keys by prioritizing the first map containing the key, falling through to subsequent maps when the key is removed from the earlier map.
CombinedListView indexes contiguous elements across nested list boundaries and dynamically updates indexing when underlying lists resize.
