Same Image URL on different components/screents?

[babyrusa]

Hi. I just want to ask if the library does caching for same image URL but on different screens? I'm done a lot of testing and I don't think it does I did some researching and found this issue https://github.com/DylanVann/react-native-fast-image/issues/394, installed the fork by @StevenMasini but I don't think it's caching same image url on different screens.

What my app has a newsfeed which has posts and images on each post. When users click on an image, it opens out a photo viewer which shows the images (similar to Facebook feed). I notice that whenever I open the photo viewer, even tho the Photo View is using (or at least what I coded it) FastImage, the images are being called again and again whenever I open the photo viewer, which leads me to believe that the images are not being cached at all. For the photo viewer, I tested with both react-native-image-zoom-viewer react-native-gallery-swiper which have the custom image component render so I used FastImage for both but nothing worked.

What I'm also suspecting is if any of my IOS libraries are outdated?

SDWebImage (5.12.3)
SDWebImageWebPCoder (0.2.5)

Let me know if my understanding is correct. Thank you
