如何在flutter中给出网格视图列表的onpress函数？

import 'package:flutter/material.dart';

class GridListPage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Grid List'),
      ),
      body: GridView.count(
        crossAxisCount: 2, // 每行显示的网格数量
        children: List.generate(10, (index) {
          return GestureDetector(
            onTap: () {
              // 在这里添加onPress函数的逻辑
              print('点击了第 $index 个网格项');
            },
            child: Container(
              margin: EdgeInsets.all(10),
              color: Colors.grey[300],
              child: Center(
                child: Text(
                  '网格项 $index',
                  style: TextStyle(fontSize: 20),
                ),
              ),
            ),
          );
        }),
      ),
    );
  }
}

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