我需要将Firestore查询中的值Map到PlutoGrid结构中右列的右单元格中，我想我已经快完成了，但最后一部分有点棘手。
这是我的主代码的一部分：

class RowInfinityScrollScreen extends StatefulWidget {
  static const routeName = 'feature/row-infinity-scroll';

  const RowInfinityScrollScreen({Key? key}) : super(key: key);

  @override
  _RowInfinityScrollScreenState createState() =>
      _RowInfinityScrollScreenState();
}

class _RowInfinityScrollScreenState extends State<RowInfinityScrollScreen> {
  late List<PlutoColumn> columns;
  late List<PlutoRow> rows;
  late PlutoGridStateManager stateManager;
  late List<PlutoRow> dBRows;

  @override
  void initState() {
    super.initState();

    columns = [
      PlutoColumn(
        title: 'Restaurants',
        field: 'name',
        type: PlutoColumnType.text(),
      ),
      PlutoColumn(
        title: 'Stars',
        field: 'star',
        type: PlutoColumnType.number(),
      ),
    ];

    // Pass an empty row to the grid initially.
    rows = [];

    // fetch data from the server,
    dBRows = rowsByColumns(length: 100, columns: columns);    
  }

  static List<PlutoRow> rowsByColumns({
    required int length,
    required List<PlutoColumn> columns,
  }) {
    return List<int>.generate(length, (index) => index).map((_) {
      return rowByColumns(columns);
    }).toList();
  }

  static PlutoRow rowByColumns(List<PlutoColumn> columns) {
    return PlutoRow(cells: _cellsByColumn(columns));
  }

  static Map<String, PlutoCell> _cellsByColumn(List<PlutoColumn> columns) {
    final cells = <String, PlutoCell>{};
    for (var column in columns) {
      cells[column.field] = PlutoCell(
        value: DbService.withoutUID().getCollection(),
      );
    }
    return cells;
  }

这是getCollection方法

Future<List> getCollection() async {
    QuerySnapshot snapshot = await bookiesCollection.get();
    List<dynamic> result = snapshot.docs.map((doc) => doc.data()).toList();
    return result;
  }

编辑：来自QuerySnapshot的数据如下所示：

{star: 4, name: Restaurant_0}
{star: 1, name: Restaurant_1}
{star: 5, name: Restaurant_2}

我希望PlutoGrid看起来像这样：

Restaurant    |  Stars
--------------------
Restaurant_0  |  4
Restaurant_1  |  1
Restaurant_2  |  5
