Allow videos to be saved to gallery

[YeDaxia]

Thanks for the job.

OS: Android 10

I try to save the video to gallery, but the result is just a pic , see the red box below:

mycode:

await AddToGallery.addToGallery(
      originalFile: File("$downloadPath/1.mp4"),
      albumName: 'test',
      deleteOriginalFile: false,
);

Hi @YeDaxia - the package doesn't support video. It's a planned feature.

I'll update the docs to show that it's just images for now.
