Question

我有一个使用Firestore的现有Flutter应用程序（可在Android / IOS上正确运行）。

目标：

我想首先让它支持网络
我想将其托管在Firebase托管上

到目前为止的结果：

在本地空白页中运行
部署到Firebase时，甚至似乎都没有运行index.html

我尝试过的事情

根据this教程：

a）在我的Firebase项目中添加了一个Web应用

b）npm install -g firebase-tools

c）firebase login

d）firebase init

==>我选择Firestore and Hosting

==>使用现有项目，选择我的项目

==>使用所有默认设置（公共目录的build / web文件夹除外）

e）flutter channel dev flutter upgrade flutter config --enable-web

f）flutter create .

g）flutter build web

h）然后，我将所有内容从build / web复制到/ web文件夹，从firebase的底部添加CDN，然后通过以下方式调用Firebase JS SDK：

错误

在chrome上本地运行时出现此错误：

(index):53 Uncaught ReferenceError: firebase is not defined

关于使用firebase deploy的页面，页面显示我成功设置了主机，但未显示index.html

取决于您如何设置Firebase api。从flutter fire开始，这里是您应该如何设置它的方法。在您的应用目录中，编辑web / index.html以添加以下内容： `

<body>
    <script src="https://www.gstatic.com/firebasejs/7.5.0/firebase-app.js"></script>
    <script src="https://www.gstatic.com/firebasejs/7.5.0/firebase-firestore.js"></script>
     <!-- ADD THIS BEFORE YOUR main.dart.js 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: ""
};
// Initialize Firebase
firebase.initializeApp(firebaseConfig);

`

将现有项目迁移到WebApp + Firebase（Firestore +托管）
