A lightweight floating action button that appears while scrolling long lists and smooth-scrolls to the top with one tap. Clean, snack-sized UI that feels native in food menus, feeds, catalogs, and dashboards.

Functionality

• Auto-show/auto-hide after a scroll threshold (configurable px).

• Smooth animated scroll to top with adjustable duration & easing.

• Haptic & ripple feedback on tap (optional).

• Positioning controls: bottom/side offsets, safe-area aware.

• Visibility logic: fade/scale in; hide when near the top.

• Icon & style customizable (arrow, chevron, text, badge).

• Theming: color, elevation/shadow, shape (pill/round), blur.

• RTL/LTR and landscape support.

• Accessibility: large hit target, semantic label (“Scroll to top”).

• State hooks: emit events when shown/hidden or after scroll completes.

• Performance-friendly: throttled listeners; no jank on long lists.
