Contrato
- 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.
