This may be a duplicate of #35. I have tried uninstalling/upgrading/restarting in various ways and it stays consistent.

I have a flutter project that compiles to a complete android app, and parts are used within a native iOS (Swift) app. We've been doing most of our development in Android, where this plugin works great, however in iOS it does not load any images and throws an exception:

'package:flutter/src/painting/image_stream.dart': Failed assertion: line 362 pos 12: '_codec != null': is not true.

I have tried using a CachedNetworkImage, as well as a CachedNetworkImageProvider (see code below, including commented out version below. Both work fine on Android, neither on iOS.

Widget getCardImage(String fileName) {
  if(fileName==null){
    fileName="default_card.png";
  }

  Widget image =  new CachedNetworkImage(imageUrl: "https://d2pjgca6juiy4m.cloudfront.net/" + fileName);
  print(image.toString(minLevel: DiagnosticLevel.info));
  return image;
  /**return new Image(

      image: new CachedNetworkImageProvider(
          "https://d2pjgca6juiy4m.cloudfront.net/" + fileName));*/

}

I've tried printing the debug string, which doesn't provide any detail, and trying to get any more detail into the object doesn't give me much. A test image (if it matters) would be https://d2pjgca6juiy4m.cloudfront.net/default_card.png. All images in this call and others throughout the all (which are all failing on iOS) retrieve PNGs from CloudFront.

See image attachment of same code working on Android and not iOS.

Thanks for providing the test image.
Does the library work for you on iOS if you use an image not served by cloudfront? Or doesn't load any image?

I can't load any image. I just tried 5 from various sources, http/https, CDN/no CDN, jpeg/png, no luck.

Note that this is an integration between a native app and a flutter app, I'm not sure if there are any required Xcode settings to allow this to work. My flutter portion is able to make API calls, so it shouldn't be an internet connection, but if there is any more data I can get for you, just let me know.

_codec != null should not occur anymore in 0.4.1. Could you have a look if you still get an error?

I will close this issue for now. If you still have a problem you can reopen it.
