Flutter:在 Android 上获取本地 IP 地址

Flutter: Get local IP address on Android

如何在 Flutter 中获取我的 (Android) 设备的本地 IP 地址? 这应该是

我暂时是这样解决的,但如果你有更好的解决方案,那将是令人愉快的:

static Future<String> getLocalIpAddress() async {
    final interfaces = await NetworkInterface.list(type: InternetAddressType.IPv4, includeLinkLocal: true);

    try {
      // Try VPN connection first
      NetworkInterface vpnInterface = interfaces.firstWhere((element) => element.name == "tun0");
      return vpnInterface.addresses.first.address;
    } on StateError {
      // Try wlan connection next
      try {
        NetworkInterface interface = interfaces.firstWhere((element) => element.name == "wlan0");
        return interface.addresses.first.address;
      } catch (ex) {
        // Try any other connection next
        try {
          NetworkInterface interface = interfaces.firstWhere((element) => !(element.name == "tun0" || element.name == "wlan0"));
          return interface.addresses.first.address;
        } catch (ex) {
          return null;
        }
      }
    }
  }
