dependencies:
  gt3_flutter_plugin: 0.1.0

配置 / Configuration

请在 官网/Official 申请验证 ID（gt）和 Key，并部署配套的后端接口。详细介绍请查阅：部署说明

Create your IDs and keys (GeeTest CAPTCHA V3) on GeeTest dashboard, and deploy the corresponding back-end API based on GeeTest documents.

示例 / Example

Init

初始化

Gt3FlutterPlugin captcha = Gt3FlutterPlugin();

或 / or

Gt3CaptchaConfig config = Gt3CaptchaConfig();
config.language = 'en'; // 设置语言为英文 Set English as the CAPTCHA language
config.cornerRadius = 5.0; // 设置圆角大小为 5.0 Set the corner radius to 5.0
config.timeout = 5.0; // 设置每个请求的超时时间为 5.0 Set the timeout for each request to 5.0 seconds
Gt3FlutterPlugin captcha = Gt3FlutterPlugin(config);

startCaptcha

启动验证

// 从服务端接口获取验证参数 Get validation parameters from the server API
Gt3RegisterData registerData = Gt3RegisterData(
    gt: ..., // 验证ID，从极验后台创建 Verify ID, created from the geetest dashboard
    challenge: ..., // 从极验服务动态获取 Gain challenges from geetest
    success: ...); // 对极验服务的心跳检测 Check if it is success
captcha.startCaptcha(registerData);

close captcha

关闭验证

captcha.close();

addEventHandler

添加处理回调

Process callback

captcha.addEventHandler(
    onShow: (Map<String, dynamic> message) async {
        // TO-DO
        // 验证视图已展示 the captcha view is displayed
        debugPrint("Captcha did show");
    },
    onClose: (Map<String, dynamic> message) async {
        // TO-DO
        // 验证视图已关闭 the captcha view is closed
        debugPrint("Captcha did close");
    },
