如何在flutter中实现可选DataRow

import 'package:flutter/material.dart';

class MyDataTable extends StatefulWidget {
  @override
  _MyDataTableState createState() => _MyDataTableState();
}

class _MyDataTableState extends State<MyDataTable> {
  List<DataRow> rows = [];
  List<bool> selectedRows = [];

  @override
  void initState() {
    super.initState();
    // 初始化数据行和选中状态
    for (int i = 0; i < 10; i++) {
      rows.add(DataRow(cells: [
        DataCell(Text('Row $i')),
        DataCell(Text('Data $i')),
      ]));
      selectedRows.add(false);
    }
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Selectable DataTable'),
      ),
      body: SingleChildScrollView(
        child: DataTable(
          columns: [
            DataColumn(label: Text('Row')),
            DataColumn(label: Text('Data')),
          ],
          rows: List<DataRow>.generate(rows.length, (index) {
            return DataRow(
              cells: [
                DataCell(Text('Row $index')),
                DataCell(Text('Data $index')),
              ],
              selected: selectedRows[index],
              onSelectChanged: (value) {
                setState(() {
                  selectedRows[index] = value!;
                });
              },
            );
          }),
        ),
      ),
    );
  }
}

void main() {
  runApp(MaterialApp(
    home: MyDataTable(),
  ));
}
