Question

您好，我正要将我的应用程序部署为APK。当我对我的手机进行调试时，一切都正常。我已经准备好把它构建成APK了。结果发生了这样的事情。这个错误一直出现，我不知道该怎么办。

我也试着在我的手机上运行它，结果发生了这种情况

我尝试了几种方法，但都不起作用。该怎么办呢。

另外，请让它更容易解释，因为我不知道在这个问题中。如果可能的话，请让我这样的笨蛋一步一步来，谢谢。我真的需要你的帮助。求求你！谢谢

看起来像是you are not connected to internet。Flutter无法下载所需的依赖项。请连接到互联网为您的第一次构建使用新的库，并运行flutter pub get，然后再次运行flutter run。

如果它起作用了，请告诉我。
