iOS端Shared_preferences抛出PlatformException通道连接异常求助

我见过很多关于这个错误的帖子，但大多和Firebase相关。这是个极简应用——无Firebase、无网络，本质是个针对特定问题的计算器。Android上运行正常，但iOS启动失败。

Pubspec.yaml依赖 #

environment:
  sdk: '>=3.0.6 <4.0.0'

dependencies:
  flutter:
    sdk: flutter
  shared_preferences: ^2.2.1
  async: ^2.11.0

dev_dependencies:
  flutter_test:
    sdk: flutter

  flutter_lints: ^2.0.3

flutter:
  uses-material-design: true

我只添加了两个库：shared_preferences（用于存储设置）和async（用于FutureGroup）。

main.dart的main函数 #

void main() {
  WidgetsFlutterBinding.ensureInitialized();
  SharedPrefs().init().then((void _) {
    SpecificModel.load();
    runApp(MyApp());
  });
}

错误发生在SharedPrefs().init()这一行（原本将main设为async并使用await，后来尝试各种方法改成了.then）。

错误输出 #

Flutter命令行运行输出 #

Xcode直接运行错误 #

直接在Xcode中运行完全无法链接，提示Framework not found shared_preferences_foundation。但通过Flutter命令行构建正常：

已尝试的解决方法 #

• flutter doctor显示一切正常，flutter pub outdated显示所有直接和间接依赖均为最新版本
• 多次执行flutter clean、rm -rf ios/Pods、rm podFile.lock、flutter pub get流程
• 清理pod缓存、取消集成、重建Flutter缓存后执行pod install
• 新建Flutter项目复制现有代码，能正常运行一段时间，但之后错误复现，因此确定问题不在代码而在环境
