Flutter智能验证码验证插件flutter_yandex_smartcaptcha的使用

示例：

import 'package:flutter/material.dart';
import 'package:flutter_yandex_smartcaptcha/flutter_yandex_smartcaptcha.dart';

// 从Yandex Cloud管理员面板获取您的密钥
String siteKey = const String.fromEnvironment('SITE_KEY');

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Yandex SmartCaptcha',
      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
        useMaterial3: true,
      ),
      home: const MyHomePage(title: 'Example'),
    );
  }
}

/// CaptchaConfig:
/// sitekey — 客户端部分的密钥。
/// languageCaptcha — 验证码的语言。'ru' | 'en' | 'be' | 'kk' | 'tt' | 'uk' | 'uz' | 'tr';
/// testMode — 启用测试模式。用户将始终收到任务。仅用于调试和测试。
/// isWebView — 在WebView中启动验证码。在通过WebView将验证码添加到移动应用程序时，可以提高评估用户的准确性。
/// invisible — 不可见的验证码。
/// hideShield — 隐藏数据处理通知块。
/// colorBackground — 背景颜色
