The same problem. It's very strange to throw exceptions when image is not available without ability to catch it. Why just not add callback if any error?

I have the same error. It only throws this error when I tried to load an image from a url whose response is 404. Is there some way to Catch this exception so that it will not throw an error on the console?

In debug mode it seems to freeze the app.

I have the same problem when call to a url return 404.

shpy2001 on 7 May 2019

I've set up with this

errorWidget: (context, url, error) => Icon(Icons.error),

but still, the app crashed when the image is 404.

so what's the point of errorWidget option?

ghprod on 27 May 2019

The error comes from visual code debugger (or somewhere around), if you use flutter run from console then all works as it should. It happened to me with my own code and I posted an issue.

@cosinus84 I tried running it using flutter run in the console and it still threw this exception. In my code, it's a large list of items with an image for each item. The weird thing is that when they get loaded for the first time no exceptions are thrown, it normally displays the error widget as it should. However, if I start scrolling the list, the exceptions start getting thrown for images with 404 response. I'm not sure what's causing that, but I'll take a look as soon as I'm done with my finals.

~~#144~~ #190 might fix this. @basselch, can you test it?

@rmarau I tested it on my app and your fix works. No exceptions are thrown while scrolling

bassel on 31 May 2019

I have the same problem. Any solution for that?

I'm using version 1.1.0 and I still get the console error dump when I recieve a 403 status code when providing an errorWidget.

I think we're running into https://github.com/flutter/flutter/issues/33427 which seems to be related to a VM problem.

Why is this issue closed? Still facing this issue with v1.1.1

YAPPDEF on 2 Oct 2019

If you're using VSCode, then this is probably a false positive from the Dart code plugin. Try and turn off the "Uncaught Exceptions" breakpoint on the debug screen.

Why this happens can be found here: https://github.com/flutter/flutter/issues/33427
It boils down to the crude way in which the dart plugin scans for errors. As I take it, it doesn't use the dart compiler to understand the code, it simply scans your code, and looks for try catch handlers (etc.), and then tries to decide if something is uncaught or not.

Does some1 know if it is fixed in 1.1.2? I still had it in 1.1.1

Klabauterman on 30 Oct 2019

Just updated to 1.1.2 and it shows me the error as INFO and not as ERROR:
