iOS PhotoKit Plugin for Flutter

A Flutter plugin to interact with PhotoKit on iOS.


To use this plugin, add flutter_photokit as a dependency in your pubspec.yaml file

Then, include the NSPhotoLibraryAddUsageDescription permission in your Info.plist


For an example on how to use this plugin, check out the sample app

For simplicity, the sample app just shows an example of saving a photo, but this plugin will work for videos as well! Usage is exactly the same.
