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

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?

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?

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.

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

Any news here?

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

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

any news on this?
