• 'DirectSelectState' is from 'package:direct_select_flutter/direct_select_list.dart' ('/C:/src/flutter/.pub-cache/hosted/pub.dartlang.org/direct_select_flutter-1.1.1/lib/direct_select_list.dart').
  Try correcting the name to the name of an existing getter, or defining a getter or field named 'DirectSelectContainer'.
  final dsListener = DirectSelectContainer.of(context);
