android - lib/home.dart :2:8: Error: Not found: 'dart:html'

Question

我是新来的，遇到了 Android Studio 的问题。我尝试运行 main.dart(ios 和 android)并收到此警告消息

** 构建失败 **

warning: Capabilities for Signing & Capabilities may not function correctly because its entitlements use a placeholder team ID. To resolve this, select a development team in the Runner editor. (in target 'Runner' from project 'Runner')```

What should I do to fix it? Many thanks for the help in the advance. I updated my Andorid studio this morning and since that time I have this issue

尝试将 main.dart 文件顶部的 dart:html 替换为 dart:io。
