Flutter应用在iOS 16设备启动即崩溃，iOS 17正常求助

我开发的Flutter应用上传至App Store后，iOS 17设备下载运行完全正常，但iOS 16设备打开即立即闪退。已经更新所有依赖库、尝试修改代码，问题仍未解决，给客户对接带来不少麻烦。

排查建议 #

• 优先获取iOS 16设备的闪退日志：通过Xcode的Organizer连接设备，查看崩溃报告的堆栈信息，这是定位问题的核心依据。
• 检查依赖库的iOS版本兼容性：部分依赖如device_info_plus: ^9.1.0、firebase_messaging: ^14.0.4可能对iOS 16及以下存在适配问题，查看对应库的文档，确认最低支持iOS版本，必要时降级到兼容版本。
• 验证Flutter SDK兼容性：当前SDK范围是>=2.18.4 <3.0.0，旧版本Flutter在适配iOS 17后可能出现iOS 16兼容问题，尝试升级到Flutter 3.x稳定版（需同步调整SDK范围）。
• 给初始化步骤添加错误捕获：用try-catch包裹Hive、Firebase等异步初始化操作，排查是否存在未捕获的异常导致闪退：

  try {
    await Hive.initFlutter();
    await Hive.openBox("user");
  } catch(e) {
    print("Hive初始化错误: $e");
  }
  try {
    await Firebase.initializeApp();
  } catch(e) {
    print("Firebase初始化错误: $e");
  }
  

• 检查iOS打包配置：确认Xcode项目的Deployment Target是否设置为iOS 16或更低，同时检查Info.plist中的权限隐私描述是否完整，iOS 16对部分权限的要求与iOS 17存在差异。
• 测试Ad Hoc包：直接用Xcode给iOS 16设备打Ad Hoc包安装测试，获取更精准的错误信息，App Store包的闪退原因可能与本地调试包不同。
