Image save on readonly mode

[Develeste]

My issue is about [Mobile]

latest flutter version in stable channel on branch master

In readOnly mode, it seems to be no way to download images displayed on the screen by touching them.

Can you tell me if it is possible and how to?

We are using ImageTapWrapper class which is based on library photo_view.
Do you have a library in mind that provides the functionality of downloading photo?

We probably can give users two options with a popup:

1. Zoom in to view
2. Save to gallery https://stackoverflow.com/questions/49987707/how-to-save-an-image-to-the-photo-gallery-using-flutter

@mrverdant13 What do you think?

I think that It is good to add a save icon button on the ImageTapWrapper using some packakge that give us saving feature.

showDialog =>

SimpleDialog(
  // no title
  children: [
    SimpleDialogItem(
      icon: Icons.save,
      color: Colors.orange,
      text: 'Save',
      onPressed: () {
        // GallerySaver.saveImage(image.path);
      },
    ),
    SimpleDialogItem(
      icon: Icons.zoom_in,
      color: Colors.green,
      text: 'Zoom',
      onPressed: () {
        // photo_view
      },
    )
