StackedColumnChartWidget class

A stacked column chart widget where multiple datasets are stacked vertically.

Each column is divided into segments representing different data series, with each segment stacked on top of the previous one. This is useful for comparing the composition of different categories while showing the total.

Features

Multiple data series stacked vertically
Customizable bar width and border radius
Interactive bar tapping with visual border highlighting
Gradient fills per segment
Loading and error states
Full theme support

Example

StackedColumnChartWidget(
  dataSets: [
    ChartDataSet(
      label: 'Q1',
      color: Colors.blue,
      dataPoints: [
        ChartDataPoint(x: 0, y: 10),
        ChartDataPoint(x: 1, y: 20),
      ],
    ),
    ChartDataSet(
      label: 'Q2',
      color: Colors.green,
      dataPoints: [
        ChartDataPoint(x: 0, y: 15),
        ChartDataPoint(x: 1, y: 25),
      ],
    ),
  ],
  theme: ChartTheme.light(),
  title: 'Quarterly Sales',
  onBarTap: (point, datasetIndex, barIndex, position) {
    // Handle bar tap
  },
)
