Hi @lvyandev, the problem here is the line in your Podfile where you say:

      ## dart: PermissionGroup.photos
      'PERMISSION_PHOTOS=0',

This actually tells the plugin to remove the part where we access the iOS PHPhotoLibrary SDK so that Apple static code analyser doesn't think you are using it when you upload your app to the App Store.

By default the permission_handler plugin assumes you want to use all SDKs and you can use the above code to disable these SDKs. This means that by default all macros are set to 1 (i.e. 'PERMISSION_PHOTOS=1') and by setting it to zero you are telling the plugin not to use the SDK. So in your case where you do want to use the PHPhotoLibrary SDK, you need to switch things around. So the solution would be to uncomment all SDKs you don't want to use and make sure you comment all SDKs you do want to use.
