[dart-misc] Got dart2JS bug ? Not sure where to fill bug report

[tomaszkubacki]

Hello,

I've created simple pi chart - using chart.js - demo app
<https://github.com/tomaszkubacki/dart_chart-bug> showing bug which I'm not
sure where to fill in.

<Loading Image...>


What I'm trying to achieve is getting the index of clicked pie chart item.

Here is line of
code: https://github.com/tomaszkubacki/dart_chart-bug/blob/master/web/main.dart#L40
where I can get the index but it only works in Dartium while debugging.
when using build dart2JS version index is always null.

So my question would be is this a bug or me using JS interop wrong way ?
If it's a bug where should I fill the issue ?

Best regards,
t.k

I ran into a Dart2JS bug too, and I reported it
here: https://github.com/dart-lang/sdk/issues

So as Jacob Richman pointed out - it's not a bug - it's just you cannot
merge package:js code and dart:js as package:js does not use wrapping.

Working version of pie chart with click support on pie item is here (if
anyone is interested):
