AnimatedPieChartView class

A widget that displays an animated pie chart with configurable appearance and behavior.

The pie chart animation can be triggered automatically when the widget is built or when it becomes visible in a scrollable view (using the provided scrollController).

This widget displays filled pie slices that represent data proportions, unlike AnimatedCircleView which draws stroke-based circles. Each slice is drawn as a filled wedge with optional stroke outlines.

Example usage:

AnimatedPieChartView(
  pieChartPainterConfig: PieChartPainterConfig(
    data: [
      PieData(value: 30, color: Colors.blue, label: 'Category A'),
      PieData(value: 45, color: Colors.green, label: 'Category B'),
      PieData(value: 25, color: Colors.orange, label: 'Category C'),
    ],
    strokeWidth: 2.0,
    separatorAngle: 0.02,
  ),
  duration: Duration(milliseconds: 1200),
)
