Flutter 颤振Web错误类型错误：dart.global.firebase.analytics不是一个函数

我使用的是以前创建的firebase移动应用程序，该应用程序在移动级别上与firebase完全兼容，但是，当我尝试将其作为chrome页面运行时，它似乎不起作用，并且在编译时会触发标题中列出的错误。颤振医生显示一切正常工作，铬是一个上市的设备。当试图构建网页时，chrome窗口中会出现一个空白屏幕

在期望web安装正常工作之前，您需要遵循for web安装

将以下内容添加到

index.html

的

正文中：

<script src="https://www.gstatic.com/firebasejs/8.4.1/firebase-app.js"></script>
<script src="https://www.gstatic.com/firebasejs/8.4.1/firebase-analytics.js"></script>

<script>
      var firebaseConfig = {
        apiKey: "...",
        authDomain: "[YOUR_PROJECT].firebaseapp.com",
        databaseURL: "https://[YOUR_PROJECT].firebaseio.com",
        projectId: "[YOUR_PROJECT]",
        storageBucket: "[YOUR_PROJECT].appspot.com",
        messagingSenderId: "...",
        appId: "1:...:web:...",
        measurementId: "G-...",
      };

      // Initialize Firebase
      firebase.initializeApp(firebaseConfig);
</script>


var firebaseConfig={
apiKey:“…”，
authDomain:“[YOUR_PROJECT].firebaseapp.com”，
databaseURL:“https://[YOUR_PROJECT].firebaseio.com”，
projectId:“[YOUR_PROJECT]”，
storageBucket:“[YOUR_PROJECT].appspot.com”，
messagingSenderId:“…”，
appId:“1:…：web:…”，
度量标准：“G-…”，
};
//初始化Firebase
firebase.initializeApp（firebaseConfig）；

您需要为您使用的每个SDK添加脚本。以上仅显示了分析的基础知识
