Flutter：没有权限处理程序的版本匹配 >5.1.0+2 <6.0.0

Question

将 Flutter 和 Dart 升级到最新版本后，我还更新了我的应用程序的依赖项。 现在，当我运行flutter pub get时，我收到以下错误：

Because no versions of permission_handler match >5.1.0+2 <6.0.0 and permission_handler 5.1.0+2 depends on permission_handler_platform_interface ^2.0.2, permission_handler ^5.1.0+2 requires permission_handler_platform_interface ^2.0.2.
And because no versions of permission_handler_platform_interface match >2.0.2 <3.0.0 and permission_handler_platform_interface 2.0.2 depends on plugin_platform_interface ^1.0.2, permission_handler ^5.1.0+2 requires plugin_platform_interface ^1.0.2.        
And because geolocator >=7.0.0 depends on geolocator_platform_interface ^2.0.0 which depends on plugin_platform_interface ^2.0.0, permission_handler ^5.1.0+2 is incompatible with geolocator >=7.0.0.
So, because MyApp depends on both geolocator ^7.0.1 and permission_handler ^5.1.0+2, version solving failed.
Running "flutter pub get" in flutter_app...                             
pub get failed (1; So, because MyApp depends on both geolocator ^7.0.1 and permission_handler ^5.1.0+2, version solving failed.)

我不太明白错误在哪里以及我能做些什么来解决它。 如果有任何信息缺失，我会尽快补充。 有谁知道我需要在依赖项中更改什么？

这是我的flutter doctor ：

那是因为这个 package 还不支持 null 安全性。 我认为您应该在他们的 GitHub 存储库上创建一个问题，而不是在这里提出问题。
