A production-ready in-page navigator that turns a chip/tab row into instant scroll-to-section controls. Bind a list of titles, feed your content via a builder, and the widget smoothly scrolls to the exact item index—with offsets that respect sticky headers and safe areas. Fully themeable with 28 parameters, silky animations, and rock-solid behavior on long, dynamic lists.

Functionality

• Tap a chip → scroll to item (by index) with configurable duration/easing.

• Content builder API: render each section/card with your own component.

• Auto sizing for dynamic rows (no hardcoded heights required).

• Header awareness: headerHeight, extraTopOffset to clear sticky bars.

• Scroll-spy (optional): highlight the active chip while the user scrolls.

• Press feedback: configurable pressScale for tactile tap states.

• Chip design controls: gap, horizontal/vertical padding, radius, border,
  active/inactive bg & text colors, start/end spacing.

• Typography controls: titleWeight, text size/contrast.

• List spacing: global sectionSpacing between items.

• Initial index & programmatic control (jump/animate to any index).

• Works with ListView, CustomScrollView/Slivers, or inside sheets.

• RTL & localization: mirrored chips and natural scroll direction.

• Accessibility: large hit targets, semantic labels, high-contrast colors.

• Performance-minded: reused cells, throttled listeners, stutter-free scrolling.

• Theme ready: light/dark palettes; card shadows/radii fit modern UI kits.

• Tested on real devices (iOS/Android) for long feeds and nested scrolls.

Great for: product pages (Specs/Reviews/FAQ), docs & help centers, category menus, analytics dashboards, and any long screen that benefits from chip-based section navigation.
