Flutter iOS应用重构后不再请求相机/相册权限问题求助

近期对Flutter iOS应用完成重构，核心操作是将main.dart中的代码拆分到独立文件。重构后应用突然不再向用户请求相机或相册权限，导致无法访问对应资源。当前环境为XCode 15、iOS 17。

已执行以下排查操作：

• 确认permission_handler插件已更新至v11.0.1
• 反复检查info.plist中权限描述键配置正确：

<key>NSCameraUsageDescription</key>
<string>We need access to your camera for taking pictures.</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>We need access to your photo library for selecting pictures.</string>

• 更新pod至1.13.0
• 更新homebrew至4.1.15
• 更新Flutter及工具至Flutter 3.13.6稳定版
• 执行flutter clean、flutter pub get等命令
• 在真机和模拟器环境多次重装应用

相关代码片段：

File? _image;
UploadState _uploadState = UploadState.idle;

Future<void> _checkPermissionsAndPickImage(
    ImageSource source, BuildContext context) async {
  Permission permission =
      (source == ImageSource.camera) ? Permission.camera : Permission.photos;

  PermissionStatus status = await permission.request();

  if (status.isGranted) {
    _pickImage(source);
  } else if (status.isPermanentlyDenied) {
    _showPermissionDeniedDialog(context);
  } else {
    print('Permission not granted. Cannot access $source.');
  }
}

异常现象：系统设置中找不到该应用的权限设置选项。
