我是新来的。我面临一个关于[ERROR:flatter/lib/ui/ui_dart_state.cc(209)]未处理异常的问题:PlatformException。

这是我的调试控制台:

此错误是在您未连接到internet时引起的。请检查您的internet连接,然后重试

检查您是否在androidManifest文件中添加了INTERNET权限。
从日志中,我可以看到您正在使用google signin,因此请确保您已将SHA-1上传到firebase控制台。如果没有,那么添加SHA-1键并替换你的谷歌服务。json文件和新文件。
如果在模拟器上运行,请检查模拟器是否可以访问internet。更多关于这个 here
