Firebase Storage Image Cache in Ionic

So I used Firebase Storage to store and retrieve images and display them in a list.

But whenever I scroll through the images in my list the app constantly requests data and my quota in Firebase gets used up quickly.

I’ve already set the cacheControl to public and max-age:150000 in the metadata but it did not work.

Is there any way to cache images from firebase storage. And if so where should I check and confirm that the images are cached.
