image_gallery_saver #

We use the image_picker plugin to select images from the Android and iOS image library, but it can't save images to the gallery. This plugin can provide this feature.
Usage #
To use this plugin, add image_gallery_saver as a dependency in your pubspec.yaml file. For example:

Your project need create with swift.
Add the following keys to your Info.plist file, located in

NSPhotoLibraryAddUsageDescription - describe why your app needs permission for the photo library. This is called Privacy - Photo Library Additions Usage Description in the visual editor

You need to ask for storage permission to save an image to the gallery. You can handle the storage permission using flutter_permission_handler.
