Hi! How do I make a slideshow like an Instagram post with multiple pictures that a user uploaded for other users to swipe through? I tried to make a PageView, but you have to have a predetermined number of pages/images to display the images—how do you make the number of pages get updated based on how many images the user uploaded? For example, if they uploaded 7 photos, the PageView changes to have 7 pages, but if the user uploaded 5 photos, the PageView changes to have 5 pages. Is there another method to make this slideshow feature?
