【问题描述】:
我有一个使用 Firebase 的 Flutter 应用,在 iOS 和 Android(模拟器和物理设备)上运行良好。
我正在尝试为 web 编译和运行它,但在尝试使用 Firebase 服务时出现错误(特别是 ConfigRemote,但我怀疑这是 Firebase 的一般问题)。
这是我第一次尝试使用 Firebase 为 web 编译,所以我在这里的知识非常有限......
我做了什么:
- 在 Firebase 控制台上添加了一个网络应用
- 将所需的脚本复制到body标签(index.html)中
- 添加了所有依赖脚本 (index.html)
<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-firestore.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-functions.js"></script>
<script src="https://www.gstatic.com/firebasejs/8.6.1/firebase-storage.js"></script>
<script src="https://www.gstatic.com/firebasejs/8.6.1/firebase-remote-config.js"></script>
<script src="https://www.gstatic.com/firebasejs/8.6.1/firebase-messaging.js"></script>
我遇到的错误(在 await ui.webOnlyInitializePlatform()):
