seems to work fine Angular is not going to know about what is cached or not. What you want to do is have an unloaded property that represents unloaded images
unloaded: number = 10;
<img src="url" (load)="unloaded = unloaded - 1">
<spinner *ngIf="unloaded"></spinner>

How to determine to use cached activity in GWT MVP?


Tag : gwt , By : Jim F.

I wish this helpful for you After so many debug, I observed the following: In CachingActivityMapper->getActivity(), the equals method returns false all the time.
So I tried to override the equals method in my place classes. But, since the equals method seems invoked in some of the other places it doesnot work.

Glide : How to find if the image is already cached and use the cached version?

hope this fix your issue
You don't need a custom ModelLoader to show the GIF from cache if present and fetch it otherwise, that's actually Glide's default behavior. Just using a standard load line should work fine:
Glide.with(TheActivity.this)
   .load("http://sampleurl.com/sample.gif")
   .diskCacheStrategy(DiskCacheStrategy.SOURCE)
   .into(theImageView);

it helps some times Just a little modification from this existing solution https://stackoverflow.com/a/57640169/5882307 worked.
Code:
  Future<Size> _calculateImageDimension() {
  Completer<Size> completer = Completer();
  Image image = new Image(image: CachedNetworkImageProvider("https://i.stack.imgur.com/lkd0a.png")); // I modified this line
  image.image.resolve(ImageConfiguration()).addListener(
    ImageStreamListener(
      (ImageInfo image, bool synchronousCall) {
        var myImage = image.image;
        Size size = Size(myImage.width.toDouble(), myImage.height.toDouble());
        completer.complete(size);
      },
    ),
  );
  return completer.future;
}
_calculateImageDimension().then((size) => print("size = ${size}")); // 487.0,696.0

Hope this helps Apparently there is no solution at the moment. See here: https://github.com/Baseflow/flutter_cached_network_image/issues/77
I use the version of the image in the address to get around this. Something like: https://example.com/image.jpg?version=14
