我想要的功能,

导入 android.telephony.TelephonyManager;

在颤振中,根据 pub.dev

包:flutter_android/android_telephony.dart

可以做同样的功能,但我无法让它工作。有人可以帮忙吗?

import android.telephony.TelephonyManager;

switch (info.getSubtype()) {
  case TelephonyManager.NETWORK_TYPE_EDGE:
    return "2G"; // ~ 50-100 kbps
  case TelephonyManager.NETWORK_TYPE_HSDPA:
    return "3G"; // ~ 2-14 Mbps
  case TelephonyManager.NETWORK_TYPE_LTE:
    return "4G"; // ~ 10+ Mbps
  case TelephonyManager.NETWORK_TYPE_UNKNOWN:
    return "unknown"; // is connected but cannot tell the speed
  default:
    return "none";
}
