Flutter运行报错：dart:html不可用及WebSocket类型未找到

Flutter应用此前运行正常，当前出现平台兼容报错，已尝试清理缓存、执行flutter clean及删除build目录，问题未解决。报错信息如下：

/C:/Users/PC/AppData/Local/Pub/Cache/hosted/pub.dev/get-4.6.6/lib/get_connect/sockets/src/sockets_html.dart:4:8: Error: Dart library 'dart:html' is not available on this platform.
import 'dart:html';
       ^
Context: The unavailable library 'dart:html' is imported through these packages:

   package:ecommapptest => package:get => dart:html

Detailed import paths for (some of) the these imports:

package:ecommapptest/main.dart => package:ecommapptest/views/introduction_screen.page.dart => package:ecommapptest/views/apphomepage.dart => package:ecommapptest/views/uicomponents/drawercontent.dart => package:ecommapptest/views/uicomponents/profile.dart => package:ecommapptest/views/testphp/testnavigationlist.dart => package:get/get_connect/sockets/src/sockets_html.dart => dart:html

/C:/Users/PC/AppData/Local/Pub/Cache/hosted/pub.dev/get-4.6.6/lib/get_connect/sockets/src/sockets_html.dart:11:3: Error: Type 'WebSocket' not found.
  WebSocket? socket;
  ^^^^^^^^^
/C:/Users/PC/AppData/Local/Pub/Cache/hosted/pub.dev/get-4.6.6/lib/get_connect/sockets/src/sockets_html.dart:11:3: Error: 'WebSocket' isn't a type.
  WebSocket? socket;

dart:html是仅支持Web平台的Dart库，当前运行环境为移动/桌面平台（如Android、iOS、Windows），但GetX 4.6.6版本的sockets_html.dart文件被错误导入，导致平台不兼容。

• 升级GetX到最新稳定版
  旧版本GetX存在平台导入逻辑缺陷，升级可修复该问题：

  flutter pub upgrade get
  

  执行后再运行flutter clean和flutter pub get，重新编译应用。

• 排查并移除不必要的Web依赖
  从导入链可知，报错源于testnavigationlist.dart间接引入了GetX的Web端WebSocket模块。若应用无需WebSocket功能，直接移除相关导入和代码；若需要WebSocket，确保使用GetX支持多平台的实现，避免仅引入Web端模块。

• 添加条件导入（自定义GetX模块时）
  若你自行封装了GetX网络相关代码，使用条件导入区分平台：

  // 自动根据平台选择对应模块
  import 'package:get/get_connect/sockets/src/sockets_io.dart'
      if (dart.library.html) 'package:get/get_connect/sockets/src/sockets_html.dart';
  

• 明确指定运行平台
  若误触发了Web平台的代码逻辑，明确指定目标平台运行，例如：

  # 运行Android
  flutter run -d android
  # 运行Windows
  flutter run -d windows
