Flutter 连接浏览器的时间出乎意料地长

Question

我正在构建 flutter web 项目，在通过 firebase 实现登录页面后，我运行 flutter run -d chrome。但在尝试连接到浏览器时它被卡住了，它只是无休止地尝试而不给出任何错误消息。状态栏:

λ flutter run -d chrome
Launching lib\main.dart on Chrome in debug mode...
Building application for the web...                                20,2s
Attempting to connect to browser instance..                             
(This is taking an unexpectedly long time.)       \

flutter 医生:

λ flutter doctor

      If the Android SDK has been installed to a custom location, set ANDROID_HOME to that location.
      You may also want to add it to your PATH environment variable.

尝试使用 flutter run -d web-server，然后在 Chrome 上手动打开 URL。
