Flutter：使用ios模拟器中的Location软件包无法获取位置

问题描述

我正在使用位置信息包Location Package来获取用户的实际位置，但是问题是，将来永远不要返回该位置，它始终保持加载状态，并且永远不返回该位置。

问题只存在于ios中，因为在android中一切正常。

我已经添加到Info.plist ios / Runner / Info.plist

<key>NSLocationAlwaysUsageDescription</key>
<string>This app needs access to location when in the background.</string>
<key>NSLocationWhenInUseUsageDescription</key>
<string>This app needs access to location when open.</string>

我已经在xcode中以后台模式检查了位置更新

并且我已经具有功能->位置->自定义位置

这是我的密码飞镖
