Abstract class error about chartjs.dart HOT 8 OPEN

Yup, just ran into the same issue. Seems as if the external factory constructors for some classes are missing.

from chartjs.dart.

Is there any update on this?

from chartjs.dart.

Sorry, I forgot this is the same issue as the one @portno logged: #22 .

from chartjs.dart.

I'm not sure if it's the same error:
I started to upgrade to Dart 2.0.0 (official stable release), I'm using chartjs: ^0.5.0 and in the javascript I imported the Chartjs 2.6.0 (like the example), but still I have this errors:
Error: The class 'ChartAnimationOptions' is abstract and can't be instantiated.
Error: No named parameter with the name 'duration'.
Error: The class 'ChartTooltipCallback' is abstract and can't be instantiated.
Error: No named parameter with the name 'title'.
Code:
ChartConfiguration config = new ChartConfiguration( type: 'doughnut', data: data, options: new ChartOptions( animation: new ChartAnimationOptions(duration: 0), tooltips: new ChartTooltipOptions( callbacks: new ChartTooltipCallback( title: allowInterop((tooltipItems, data) { return data.labels[tooltipItems[0].index] + ": " + "${data.datasets[tooltipItems[0].datasetIndex].data[tooltipItems[0].index]}%"; }), label: allowInterop((tooltipItem, data) { return; })))));

With the previous version of dart worked.

I have the same problem.
When I try to inherit an abstract class, I get the error: Uncaught TypeError: Class extends value undefined is not a constructor or null

Pull requests are welcome. I built this sample out as example of Dart-JS interop. I don't have the bandwidth to maintain it actively.

Thank you! I have already added the factories I need

from chartjs.dart.

ChartAnimationOptions is still missing its options. I'd add it but I'm not sure how to handle the callbacks. :-/
