您可以从DataGridSource.effectiveRows属性中寻找单击的DataGridRow，然后使用该行从DataGridSource.dataGridRows属性中寻找索引，以取得文件索引。现在，您可以使用该索引从快照撷取文件详细数据。

程式码片段：

SfDataGrid(
            source: employeeDataSource,
            columns: getColumns,
            onCellTap: (details) {
              if (details.rowColumnIndex.rowIndex != 0) {
                final DataGridRow row = employeeDataSource
                    .effectiveRows[details.rowColumnIndex.rowIndex - 1];
                int index = employeeDataSource.dataGridRows.indexOf(row);
                var data = snapshot.data!.docs[index];
                Navigator.of(context).push(MaterialPageRoute(
                    builder: (context) => DataGridRowInfoPage(data)));
              }
            },
          );

在数据网格行信息页中：

import 'package:cloud_firestore/cloud_firestore.dart';
import 'package:flutter/material.dart';

class DataGridRowInfoPage extends StatefulWidget {
  const DataGridRowInfoPage(this.data, {Key? key}) : super(key: key);

  final QueryDocumentSnapshot<Object?> data;

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

class DataGridRowInfoPageState extends State<DataGridRowInfoPage> {

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Flutter DataGrid'),
      ),
      body: Center(
        child: Text('Employee salary: ${widget.data.get('salary')}'),
      ),
    );
  }
}
