PrismTimeline class

A vertical timeline of events, with connectors drawn between markers.

Good for order tracking, audit logs, activity feeds, changelogs and onboarding checklists. Entries accept arbitrary child content, so each node can expand into a card without leaving the timeline.

PrismTimeline(
  entries: [
    PrismTimelineEntry(
      title: 'Order placed',
      timestamp: '09:12',
      semantic: PrismSemantic.success,
      icon: Icons.check,
    ),
    PrismTimelineEntry(
      title: 'Out for delivery',
      subtitle: 'Driver: Sam ยท 2 stops away',
      timestamp: '09:48',
      isActive: true,
    ),
  ],
