Gets attribute as expected, but throws StateError too about dart-xml

[renggli]

Hard to tell what is going on. Can you post the full stack trace of the StateError, or a reproducible minimal example?

[DavidBucienski]

Here is stack trace:
I/flutter ( 7708): StateError is thrown
I/chatty ( 7708): uid=10146(com.example.part1) 1.ui identical 7 lines
I/flutter ( 7708): StateError is thrown
I/flutter ( 7708): itunesImage | https://image.simplecastcdn.com/images/8862bce3-8814-46a6-9b72-a533960bbd50/5dd1869a-dac7-4edc-acb6-f791663f6fd1/3000x3000/wim176-frisby-ep-01-v001.jpg?aid=rss_feed

I just added a finally after the StateError {} and it is showing in stack trace the expected itunesImage value. And then showing the initial value I declared in the begin of the factory. I have to create a minimal viable project for you that demos this behavior. Should have this for you within 24 hours.

I'd like to see where the full stack of where the StateError is thrown, not where it is handled :-)

[DavidBucienski]

I don't know how to do that. I took the time to make a MVP, it is 280MB, tried to paste it here and got file too big error. How do I get this to you?

[DavidBucienski]

Ok, just discovered on StateError catch (e, s) is this what you want?

Yes, perfect: Looks like RssItem.parse calls first on an empty collection (package:fake_throw/models/rss_item.dart:21:75). Look for the bug there ...

[DavidBucienski]

Upon, further investigation this issue shows itself for a specific RSS feed. Tested 6 feeds and it's only the one. That bad one validated as proper XML, too. I though it was related to the string query on the end of the url, but it's not. I will just need to work around this. Dart XML extracts all the values and throws. So I still get the values I need.

[DavidBucienski]

Ok, your Dart XML package is solid, doing exactly what it should be doing. The RSS feed that was giving me problems has items where the iTunes:image element is missing. The file is close to 4k lines long and they don't go missing till near the very end.

[DavidBucienski]

Sorry for bothering you with this non-existent issue.
