Image request not being cancelled when item is disposed

I have a ListView with, say, 400 items.
Each item has it's own Image

If I scroll past 100 items (without stopping), then come back to them, these 100 items would have their images downloaded, meaning even when the item was no longer visible, the image request was not cancelled.

There is no callback to recycle an item inside the ListView, and I know it's automatic. But does CachedNetworkImage not cancel it's request when it's been disposed?
