 ### 使用
+#### 添加WebView
+
+使用CustomWebView组件来显示WebView。
+```dart
+import 'package:flutter/material.dart';
+
+import '../clx_webview_flutter.dart';
+
+abstract class CaptchaUtil {
+  static Future<bool>? generateCaptcha(
+      {required BuildContext context,
+      required String uri,
+      required Future<bool> Function(JavaScriptMessage message)
+          onCaptchaGenerated}) async {
+    return await Navigator.push(context, PageRouteBuilder(
+      pageBuilder: (context, animation, secondaryAnimation) {
+        final CustomController customController = CustomController.loadRequest(
+            requestedUrl: Uri.parse(uri), title: '验证码');
+        customController.setJavaScriptChannels(JavaScriptChannel(
+          name: 'H5CallFlutterInterface',
+          callback: (message) async {
+            if (!context.mounted) {
+              return CLXResult.fail(Exception('context not mounted'));
+            }
+            final result = await onCaptchaGenerated(message);
+            if (result) {
+              Navigator.pop(context, true);
+              return CLXResult.fail(Exception('captcha failed'));
+            } else {
+              customController.controller.reload();
+              return CLXResult.succ(result);
+            }
+          },
+        ));
+        return CustomWebView(customController: customController);
+      },
+    ));
+  }
+}
+```
+外部控制方法监听
+```dart
+import 'dart:async';
+import 'dart:convert';
+
+import 'package:coal_trade/api/base_model.dart';
+import 'package:coal_trade/app/environment.dart';
+import 'package:get/get.dart';
+import 'package:clx_webview_flutter/clx_webview_flutter.dart';
+
+abstract class VerificationCodeManager {
+  /// 发送登录验证码
+  static Future<bool> sendLoginCode(String phoneNo) async {
+    final result = await CaptchaUtil.generateCaptcha(
+      context: Get.context!,
+      uri: Config.slideVerifyUrlNew,
+      onCaptchaGenerated: (message) async {
+        final data = json.decode(message.message);
+        final result = await fetchAsync(
+          Method.post,
+          url: '/trade-operation/app/public/login/captcha/send',
+          params: {
+            'mobile': phoneNo,
+            'sceneId': data['sceneId'],
+            'captchaVerifyParam': data['captchaVerifyParam'],
+          },
+        );
+        return Future.value(result.isSuccess);
+      },
+    );
+    return result == true;
+  }
+}
+```
 
 #### 获取标题
 ```dart
