SvgPicture.network - Unhandled Exception: HttpException: Could not get network asset

[lemmerel]

When using SvgPicture.Network and the image could not be found, it throws the unhandled exception:

Unhandled Exception: HttpException: Could not get network asset, uri = http://127.0.0.1:1323/icon/person.svg

Version 2.0.3.

Could be fixed with try/catch and a parameter onException (as placeholderBuilder doesn't seem to affect it).

I'm trying to remember how this works with Image.network. But.. I think throwing an exception is the right thing to do here?

[lemmerel]

Thank you for your quick reply, @dnfield.

 @override
  Future<Uint8List?> prepareMessage(BuildContext? context) {
    try {
      return httpGet(url, headers: headers);
    } catch (HttpException) {
      throw HttpException;
    }
  }

Let me know what you think.

      Widget build(BuildContext context) {
    var res;

    try {
      res = SvgPicture.network(url,
          color: color,
          width: width,
          height: height,
          placeholderBuilder: placeholderBuilder);
    } on HttpException {
      res = Container();
    }
    return res;
  }

What am I doing wrong?

[dnfield]

Ok.

To do what you want here, you'd need some kind of errorBuilder parameter on the SvgPicture.network constructor.

Right now that's not implemented but probably isn't too hard.

[lemmerel]

I, and I'm sure all of your other very grateful users, would really appreciate it if you did that.

Any news here?

This has been waiting on dnfield/vector_graphics#196

Ah my bad! Thank you so much for your work :)

Next steps will be to publish new vector_graphics* and then use it in flutter_svg.

[glacials]

Thanks for your hard work! Seems like vector_graphics is all set, can this be pulled into flutter_svg?
