![]() Added 'final' to the example class `EntryItem` that extends `LinkedListEntry` from 'dart:collection'. The code as written now produces the error: ``` The type 'EntryItem' must be 'base', 'final' or 'sealed' because the supertype 'LinkedListEntry' is 'base'. ``` Also applied dartfmt to get new line break locations.
