MultiSegmentLinearIndicator class

A multi-segment linear indicator that shows multiple progress values.

This widget displays multiple progress segments in a single bar, useful for showing breakdowns or multiple metrics.

Example usage:

MultiSegmentLinearIndicator(
  segments: [
    LinearSegment(start: 0.0, end: 0.3, color: Colors.green, label: 'Complete'),
    LinearSegment(start: 0.3, end: 0.6, color: Colors.yellow, label: 'In Progress'),
    LinearSegment(start: 0.6, end: 0.8, color: Colors.orange, label: 'Pending'),
  ],
  width: 300,
  lineHeight: 25,
  showLabels: true,
)
