Flutter: How to update ValueNotifier for individual List item

Question

I have a List builder with is creates cards with content. In this card i have a button and Text widget. Basically, i want to update Text widget when i press the button. I tried to use ValueNotifier and it worked. But it updating values of every List item.

Here is main functionality:

I created ValueNotifier variable

class SelectedOrganizationStructure extends StatefulWidget {
  static ValueNotifier<String> lastLoginDate = ValueNotifier('Last login');
  final List<OrganizationUnitEntity> organizationStructure;
  const SelectedOrganizationStructure(this.organizationStructure, {Key? key})
      : super(key: key);

  @override
  State<SelectedOrganizationStructure> createState() =>
      _SelectedOrganizationStructureState();
}

And i set it to Text widget Text(SelectedOrganizationStructure.lastLoginDate.value), and when i press the button i set it's value to current date like this:

final _dateTime = DateTime.now();
final _loginDate = DateFormat('dd.MM HH:mm').format(_dateTime).toString();

onTap: () {
  SelectedOrganizationStructure.lastLoginDate.value = _loginDate
},

How i said before, this sets current date for all the card item in list builder. How can i make it update only card in witch button was pressed?
