在flutter中使用高德地图，突然报如标题的错误，一开始我以为是plist文件没有加位置授权，一检查发现权限都有，想着以前这定位都正常的，应该是改了其他地方引起定位不了的，一一对比，是我permission_handler这个插件升级了，升级后ios这边要在podfile文件下加一下权限配置

target.build_configurations.eachdo |config|

# You can remove unused permissions here

# for more infomation: https://github.com/BaseflowIT/flutter-permission-handler/blob/master/permission_handler/ios/Classes/PermissionHandlerEnums.h

# e.g. when you don't need camera permission, just add 'PERMISSION_CAMERA=0'
