I use photo_view version 0.12.0.
I have two imageProvider, and I need to change them via a button in the page to show by the widget PhotoViewGallery. They download images and show correctly.
But there's a little problem, the loading widget only show when the first imageProvider loading, when I change the imageProvider, the loading widget not show when imageProvider loading, and image will show correctly when imageProvider load complete.

My flutter version is 2.2.3

I found that when imageProvider changed in ImageWrapper, you only change the listener of imageProvider's ImageStream, but is not set the _loading to true, so the loadingWidget do not show.
