Answer 1

  List list = list to search;
  List matchingList = list of strings that you want to match against;

  list.where((item) => matchingList.contains(item.relevantProperty));

If the number of items in list is large, you might want to do:

  List list = list to search;
  List matchingList = list of strings that you want to match against;

  final matchingSet = HashSet.from(matchingList);

  list.where((item) => matchingSet.contains(item.relevantProperty));

Or else just always store the matching values as a hashset.
