Flutter插件sstp_flutter的使用_SstpFlutter 是一个用于 SSTP VPN 连接的 Flutter 插件

SstpFlutter 是一个用于 SSTP VPN 连接的 Flutter 插件。它提供了一种方便的方式来管理 SSTP VPN 连接，监控连接状态，并配置各种设置。

Flutter插件sstp_flutter特性

• 连接到 SSTP VPN 服务器
• 监控连接状态和持续时间
• 获取下载和上传速度
• 启用和禁用 DNS
• 启用和禁用代理
• 保存服务器数据以便快速连接
• 检查最后的连接状态
• 获取已安装的应用并管理允许的应用

Flutter插件sstp_flutter开始使用

要在项目中使用此插件，你需要在 pubspec.yaml 文件中添加 sstp_flutter 作为依赖项。

dependencies:
  sstp_flutter: ^version

然后运行 flutter pub get 来安装依赖项。

iOS 设置

1. 添加功能

在 Runner 的目标中添加“网络扩展”功能，并启用“数据包隧道”。

2. 添加新目标

点击底部左下角的 + 按钮，选择“NETWORK EXTENSION”。并将语言和提供者类型设置为“Objective-C”和“Packet Tunnel”，如图所示。

3. 为 sstp_extension 添加功能

对上一步创建的新目标（sstp_extension）重复步骤 1。

4. 添加 Pod 依赖

打开你的 Podfile，并添加以下行：

target 'sstp_extension' do
  pod 'vpn_adapter_ios', :git => 'https://github.com/NavidShokoufeh/vpn_adapter_ios.git', :tag => '1.0.0'
end

在你的 Runner 目标中也这样做：

target 'Runner' do
pod 'vpn_adapter_ios', :git => 'https://github.com/NavidShokoufeh/vpn_adapter_ios.git', :tag => '1.0.0'  # 添加这一行
  flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
  target 'RunnerTests' do
    inherit! :search_paths
  end
end

5. 复制粘贴代码

打开 sstp_extension > PacketTunnelProvider.m 并复制粘贴以下脚本：

PacketTunnelProvider.m

示例

以下是一个完整的示例代码，展示了如何使用该插件进行 SSTP VPN 连接管理。

  TextEditingController passController = TextEditingController();

  [@override](/user/override)
  void initState() {
    super.initState();
    init();
  }

  init() async {
    connectionStatus = await sstpFlutterPlugin.checkLastConnectionStatus();
    setState(() {});
