Create the list of the headers to be used in data table with types. Header list should be in a prioritized order, all columns have a flex value that all cells inside that column will be used.

  List<ExpandableColumn<dynamic>> headers = [
    ExpandableColumn<int>(columnTitle: "ID", columnFlex: 1),
    ExpandableColumn<String>(columnTitle: "First name", columnFlex: 2),

Create the list of the rows to be used in data table. All row list elements must contain all columns for lists.

  List<ExpandableRow> rows = userList.map<ExpandableRow>((e) {
    return ExpandableRow(cells: [
      ExpandableCell<int>(columnTitle: "ID", value: e.id),
      ExpandableCell<String>(columnTitle: "First name", value: e.firstName),
