when using a url that get a random image every time on multiple widgets, the same image result shows-CodePudding

all my Firestore documents contain a field called image_path, which has the Unsplash random source URL,

as you can test, every time you opened that link it gives a different random image. but in my flutter app, in the Image.network Row's children in SingleChildScrollView, all of them get the same random URL,

       SingleChildScrollView(
            child: Row(
              children: List.generate(lengthOfDocuments),
              (index) => ImageBox(
                documentsList[index]["image_path"], // image_path == https://source.unsplash.com/random/
              ),
            ),
          );

but they show the same image :

what I am expecting: that all images should get a randomly different image from that URL

what can be the reason for this behavior, and am I forgetting something?

CodePudding user response：

There must be some kind of caching happening in the browser or on unsplash end.

Try making the url unique for each index like so:

documentsList[index]["image_path"]   `?index=${index}`

If that doesn't change between page reloads then you could make the query param a random # or string.
