A video trimmer example created v Flutter.
Used image_picker to choose video from gallery. It browse default library path to choose media.
For iOS : If you want to choose media from camera roll (not root library list),
you need to modify just a row in image_picker's FLTImagePickerPlugin class.
_imagePickerController.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
Then video_player, gallery_saver and ffmpeg is enough for everything.
Enjoy and add new functions... for ex: crop and effect
