AnimatedCircularChartState class
The state for a circular chart that animates when its data is updated.
When the chart data changes with updateData an animation begins running.
An app that needs to update its data in response to an event can refer to the AnimatedCircularChart's state with a global key:
GlobalKey<AnimatedCircularChartState> chartKey = new GlobalKey<AnimatedCircularChartState>();
...
new AnimatedCircularChart(key: chartKey, ...);
...
chartKey.currentState.updateData(newData);
