我将 Firestore 用于我的 Flutter 应用程序。

当我在模拟器上禁用 Internet 连接时，控制台上会出现此错误：

V/NativeCrypto( 6278): Read error: ssl=0xa4621708: I/O error during system call, Software caused connection abort

但是，该应用程序在断开连接后仍照常运行。我读到过类似的错误，人们说这是一种正常行为，只有在需要重试建立连接时才应处理该错误。

这是正常行为吗？或者如果不是，我应该如何处理？

您可以在调用 Firestore 的函数之前执行网络检查以避免此异常。要检查网络连接，我建议您使用Connectivity包。它使用起来非常简单，适用于 Android 和 iOS。
