Is your feature request related to a problem? Please describe.
Normally an image gallery can be paged back and forth. Showing the images in a loop is very common.

Describe the solution you'd like
The PageView does support this. See example https://dartpad.dartlang.org/8c9075a0896138df116715ea36186506 or https://gist.github.com/Blasanka/a870803bb57bb57caf7eea11698e5a19. You just need to remove the itemCount parameter and make that not required anymore. I tried it out on my end but with no luck so far.

Describe alternatives you've considered
I could not found any other way.
