I can create a regular piechart just fine but when i add

defaultRenderer: new charts.ArcRendererConfig(arcWidth: 10)

the piechart will disappear and i get the error

type 'List<ArcRendererElement<dynamic>>' is not a subtype of type 'List<ArcRendererElement<Object>>?' in type cast

any idea on how to fix this?

@codexcer Had the same issue, can be solved by changing the defaultrenderer to:

defaultRenderer: charts.ArcRendererConfig<Object>(arcWidth: 10)

I think that is because of an error in the documentation. Seems like they did not kept it up to date with the new versions of flutter and dart.
