如何解决Flutter:使用ios模拟器中的Location软件包无法获取位置
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
