Issue since FLUTTER 2.0 upgrade

[GusRodrigues86]

I'd forked the project and published the fix @locrianmark
https://pub.dev/packages/flutter_circular_chart_two

[locrianmark]

ancestorStateOfType has been depreciated.
final AnimatedCircularChartState result = context.ancestorStateOfType(const TypeMatcher());
becomes:
final AnimatedCircularChartState result = context.findAncestorStateOfType();

@GusRodrigues86 thanks. Gotta ditch this library asap, but your fork just saved me some time 🙌

[xjodoin]

for a null safety version https://pub.dev/packages/awesome_circular_chart

@xjodoin I am unable to update the chart using your fork. This is what I am getting when I run widget._chartKey.currentState!.updateData(nextData);

I don't think is related to the project. Did you try to set the explicitly the size https://stackoverflow.com/questions/64947936/flutter-errorfailed-assertion-line-1785-pos-12-hassize

[GusRodrigues86]

Set the mainAxisSize to minimum.
