useExistingImageAsPlaceholder

If enabled and the image request has no placeholder, the current image displayed by the AsyncImagePainter/AsyncImage/SubcomposeAsyncImage will be used as the placeholder for this image request. If disabled (the default), the image request's placeholder is always used as the placeholder even if it is null.

When used with crossfade this allows crossfading between subsequent image requests without manually setting the placeholder to the previous image.

NOTE: This configuration option only works with Compose targets.
