Download image with url but it doesn't show in galery - firebase

Question

I'm using the code from the example of this dependencie image_downloader: ^0.31.0, the problem is that it doesn't show any error but the image doesn't go to the galery.
This screen is to show the images from firestore and create listtyle that when the user clicks the image is suposed to download it.

}

}
