Turn a chip/tab row into a buttery-smooth, in-page navigator. This scroll to index widget binds a list of titles, renders your content via a builder, and glides to the exact item—respecting sticky headers, safe areas, and long dynamic lists. Theme it your way and ship it to production. 🚀

Functionality

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

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

• 📏 Auto sizing for dynamic rows—no hardcoded heights.

• 🛡️ Header-aware offsets: headerHeight + extraTopOffset to clear sticky bars.

• 🕵️ Scroll-spy (optional): auto-highlight the active chip while users scroll.

• 🎛️ Press feedback with pressScale for tactile taps.

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

• 🔤 Typography: titleWeight, text size/contrast.

• 📐 List spacing: global sectionSpacing between items.

• 🚦 Initial index & programmatic control: jump/animate to any index.

• 🧵 Works inside ListView, CustomScrollView/Slivers, sheets & modals.

• 🌍 RTL & i18n: mirrored chips and natural scroll direction.

• ♿ Accessible: large hit targets, semantic labels, high-contrast palettes.

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

• 🎨 Theme ready: light/dark, card shadows/radii to match your design system.

• 📱 Device-tested (iOS/Android) for long feeds & nested scrolls.
