// 初始化 Firebase 配置
var config = {
apiKey: "your_api_key",
authDomain: "your_project_id.firebaseapp.com",
databaseURL: "https://your_project_id.firebaseio.com",
projectId: "your_project_id",
storageBucket: "your_project_id.appspot.com",
messagingSenderId: "your_sender_id"
};
firebase.initializeApp(config);
</script>
<style>
body { margin: 0; overflow: hidden; }
#flutter-container { width: 100%; height: 100vh; }
</style>

<body>
<div id="flutter-container"></div>
<script src="main.dart.js" type="application/javascript"></script>
</body>
</html>这段代码展示了如何在HTML中嵌入Flutter应用。首先，它引入了必要的Firebase JavaScript SDK库以进行身份验证和数据库操作。然后，它通过firebase.initializeApp()初始化Firebase配置。最后，它定义了一个#flutter-container div，用于在页面上显示Flutter应用。注意，你需要替换your_api_key, your_project_id, your_sender_id等配置信息为你自己的Firebase项目信息。
