使用wifi_configuration Flutter

问题描述

请问如何使用wifi_configuration包连接到开放热点-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。 是否有其他可以连接到打开的热点的库，或者是否可以通过使用wifi_configuration库来做到这一点？ 苹果提到我们只需要传递两个参数，即ssid和packagename

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

我重写了connectToWifi方法以仅接收一个参数，但这不起作用。 预先感谢

解决方法

您可以在下面复制粘贴运行完整代码
您可以使用软件包https://pub.dev/packages/wifi_utils
您可以致电Wifi.connection并提供ssid和password
代码段

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