string - how to check for word phrases as well as words in lists in flutter

Question

I am using below code to filter the text elements from the List A and List D and in which I am successful. Upon printing I am able to get word by word result.

  List A = ["ra", "rb", "rc","ball of ", "rd", "re"];
  List D = ["p", "of","of iron" ,"r", "ball of ", "s", "a"];
    
      String text = "This is a ball of iron";
    
    
bool filterLists2(text) { return [ A ].any((list) => list.contains(text)); }
List newString = text.toLowerCase().split(' ').where(filterLists2).toList();

    bool filterLists1(text) { return [ D ].any((list) => list.contains(text)); }
    List ns = text.toLowerCase().split(' ').where(filterLists1).toList();

But as the word by word separation is done and so the result is also available at the same time I also want to check for the phrases of words if there are any in the text and so in the lists which are being filtered.

How can I do that ? Please guide me
