我试图遵循这篇文章中的想法：在web中使用Flutter firebase实时数据库，使我的移动应用程序也能在web上工作，使用firebase实时数据库。
我添加了import 'package:flutter/foundation.dart' show kIsWeb;来检查是否是web。我添加了(firebase_database:^7.1.1用于移动(和(firebase:^9.0.1用于网络(包。我在index.html:中添加了导入
<script src="https://www.gstatic.com/firebasejs/8.6.1/firebase-app.js"></script>
<script src="https://www.gstatic.com/firebasejs/8.6.1/firebase-analytics.js"></script>
<script src="https://www.gstatic.com/firebasejs/8.6.1/firebase-auth.js"></script>
<script src="https://www.gstatic.com/firebasejs/8.6.1/firebase-database.js"></script>
我做了一个查询并为web运行，它运行得很好，但当我回到运行到移动设备时，我不能。

我删除了firebase包。我认为这是一个9.0.1的防火基地，它起到了的作用
官方包现在支持web，因此我们可以将其用于移动和web。谢谢你的帮助。
