如何在flutter.dart中连续检查互联网访问，而不是连接 [英] How do you check internet ACCESS continously in flutter.dart, not connection

问题描述

您如何连续检查互联网访问?我能够显示wifi是否已连接或移动数据.但是，并非所有连接都可以访问互联网.

how do you continously check internet access? I was able to show if wifi is connectected or mobile data. However, not all connection would have internet access.

 import 'package:connectivity/connectivity.dart';

var connectivityResult = await (Connectivity().checkConnectivity());
if (connectivityResult == ConnectivityResult.mobile) {
  // I am connected to a mobile network.
} else if (connectivityResult == ConnectivityResult.wifi) {
  // I am connected to a wifi network.
}

这是当前正在使用的代码. 我希望有人可以不断检查互联网访问吗?

This is currently the code im using. I was hoping how someone could check continously of internet access?
