如何通过onTap触发Grid布局中的每个网格的URL？每个网格应打开一个不同的URL

Question

所以我在这里有两个列表：
image：包含显示在网格图块上的图像。
directLinks：包含应由“ onTap”打开的每个网格图块的链接

我不想为每个网格the grid looks like this分配launch_url。该怎么办？ 每个网格图块都应将我转移到WebView中显示的新网站。 没有为每个网格图块分别键入url的情况下，我没有找到任何合适的方法。抱歉，我是初学者。

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