使用 wifi_configuration Flutter 连接到开放无线

Question

请问如何使用 wifi_configuration 包连接到开放的热点 - 无线 - 因为我刚刚找到了一种允许连接到加密无线网络的方法。

WifiConfiguration.connectToWifi("wirelessname","wirelesspassword","packagename");

在 WifiConfiguration 类中，只有一种方法可用于连接。 是否有任何其他库可以连接到开放热点，或者有没有办法通过使用 wifi_configuration 库来做到这一点？ 苹果提到我们只需要传递两个参数，当然是 ssid 和包名

init(ssid: String)
Creates a new hotspot configuration, identified by an SSID, for an open Wi-Fi network.

我重写了 connectToWifi 方法，只接收一个参数，但这不起作用。 提前致谢

您可以在下面复制粘贴运行完整代码
你可以使用包https://pub.dev/packages/wifi_utils
您可以拨打Wifi.connection并提供ssid和password
代码sn-p

import 'package:wifi/wifi.dart';
...
Future<Null> connection() async {
    Wifi.connection(ssid, password).then((v) {
      print(v);
    });
  }
