ps:当我在没有internet的情况下运行应用程序时,应用程序崩溃。

错误堆栈跟踪显示:

Emitted 'error' event on ClientReadableStreamImpl instance at:

这意味着抛出错误是因为流正在发出错误事件,而您没有处理该事件。您可以通过对正在读取的流调用
stream.on('error',callback)
来修复此问题。

这是一个DNS错误。DNS是一种用于internet连接的服务。您的应用程序正在尝试访问internet,特别是Firestore,但无法访问。这就是为什么会有错误。这个问题没有简单的解决办法,因为你还必须对应用程序的行为进行编程,才能在脱机时正常运行。

关于你的最后一句话,你是说你在没有互联网的情况下运行应用程序时看到了这个错误,还是说你在有互联网的情况下运行应用程序时看到了这个错误,当你在没有互联网的情况下运行应用程序时,你会看到其他错误吗?在有互联网连接的情况下工作正常,在没有互联网的情况下崩溃。
