PyramidChartWidget class

A pyramid chart widget displaying hierarchical data in a pyramid shape.

Each segment represents a category, with the largest at the bottom and smallest at the top, creating a pyramid visualization. Useful for displaying hierarchical data such as population distribution or sales funnels.

Features

  • Hierarchical data visualization
  • Interactive segment tapping with visual border highlighting
  • Gradient fills
  • Smooth animations
  • Full theme support

Example

PyramidChartWidget(
  data: [
    PieData(label: 'Level 1', value: 100, color: Colors.blue),
    PieData(label: 'Level 2', value: 75, color: Colors.green),
    PieData(label: 'Level 3', value: 50, color: Colors.orange),
    PieData(label: 'Level 4', value: 25, color: Colors.red),
  ],
  theme: ChartTheme.light(),
  title: 'Sales Funnel',
  onSegmentTap: (segment, segmentIndex, position) {
    // Handle segment tap
  },
)
