Flutter web firebase/firestore错误运行

Question

我正在尝试使用 firebase（身份验证、firestore 数据库、存储）作为我的 Flutter 应用程序的后端。在 Android/iOS 上一切正常，但是当我尝试为 Flutter Web 提供服务时，它因错误而崩溃，我没有找到答案。

请您提出一些修复建议？谢谢。

我想通了

添加网络支持时从firebase生成的文件，注意添加所有需要的文件。 Firebase 控制台仅生成 firebase-app.js 和 firebase-analytics.js ，所以如果你使用一些firebase-firestore.js、firebase-auth.js或firebase-storage.js，你必须自己把它放在那里。最好在文档中提及。

<script src="https://www.gstatic.com/firebasejs/7.14.4/firebase-auth.js"></script>
<script src="https://www.gstatic.com/firebasejs/7.14.4/firebase-storage.js"></script>

    var firebaseConfig = {
        apiKey: "YOUR_API_KEY",

        storageBucket: "STORAGE",

    };
    // Initialize Firebase
    firebase.initializeApp(firebaseConfig);
