Flutter运行Ios真机时报错：Failed to register observatory port with mDNS with error
报错如下
[VERBOSE-2:FlutterObservatoryPublisher.mm(101)] Failed to register observatory port with mDNS with error -65555.
[VERBOSE-2:FlutterObservatoryPublisher.mm(103)] On iOS 14+, local network broadcast in apps need to be declared in the app's Info.plist. Debug and profile Flutter apps and modules host VM services on the local network to support debugging features such as hot reload and DevTools. To make your Flutter app or module attachable and debuggable, add a '_dartobservatory._tcp' value to the 'NSBonjourServices' key in your Info.plist for the Debug/Profile configurations.
解决：（参考上述官方链接文档）
On iOS 14 and higher, enable the Dart multicast DNS service in the Debug version of your app to add debugging functionalities such as hot-reload and DevTools via flutter attach.
-
1、将应用程序的Info.plist重命名为Info-Debug.plist。复制一个名为Info-Release.plist的副本，并将其添加到Xcode项目中。
-
2、在Info-Debug.plist中，添加键NSBonjourServices并将值设置为 _dartobservatory._tcp
（可选）将键NSLocalNetworkUsageDescription添加到所需的自定义权限对话框文本中。（备注：‘Allow Flutter tools on your computer to connect and debug your application.This prompt will not appear on release builds.’）
-
3、在target’s build settings, 修改 Info.plist File 路径 path/to/Info.plist 为 path/to/Info-$(CONFIGURATION).plist.
-
4、在 target’s -> Build Settings > Build Phases > Copy Bundle Resources build phase, 如果有Info-Release.plist 删除即可（下图我已经删除）
