error-handling - Flutter:关闭互联网连接后出错 - "Error while applying io.flutter.console.FlutterConsoleFilter@70f92821 to ' W/zzajf (5265)”

Question

我将 Firestore 用于我的 Flutter 应用。

当我在模拟器上禁用互联网连接时，此错误出现在控制台上:

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

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

这是正常行为吗？或者，如果不是，我应该如何处理？

您可以在为 Firestore 调用您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包裹。它使用起来非常简单，适用于 Android 和 iOS。
