Research direction

Start at CachedNetworkImageProvider and reproduce the issue with a missing image while maxWidth or maxHeight is set. Verify that the image stream closes and that a FutureBuilder or retry can request the image again without an existing listener blocking it.

Written by the indexing model from the issue text.

Description

If image (DOES NOT EXIST) AND (maxWidth/maxHeight) ARE set, the stream never closes and there is endless waiting for the image. Especially a problem when trying to get images in a FutureBuilder or when doing a retry to get the image again, nothing happens as an image streamlistener is already running.

This is in the context of a CachedNetworkImageProvider.

Removing (maxWidth/maxHeight) solves the issue. Then the stream closes and things work as they should.
