A premium bottom navigation bar featuring a curved “spotlight” ridge that lifts the active tab into a soft, glowing circle. Text labels sit below icons for clarity, while the floating container and layered shadows add depth. With 43 parameters, this bar adapts perfectly to ecommerce, social, media, and dashboard apps on iOS and Android.

• Curved spotlight highlight: concave wave + raised circular focus for the active tab (glow/elevation configurable).

• Icons with labels: toggle labels on/off, control font, size, weight, spacing, and per-tab titles.

• Rich animations: scale, lift, fade, slide, and glow with custom durations and curves.

• Floating container: adjustable corner radius, elevation, shadow/blur, background (solid or gradient).

• Per-tab colors & sizes: separate active/inactive icon and label colors, icon size, spacing, and padding.

• Badges: dot or numeric counters for notifications on any tab.

• Behavior controls: initial index, state persistence, hide/reveal on scroll, sticky/overlay modes.

• Safe-area aware: works with notches, gesture insets, and bottom paddings; iOS & Android ready.

• Haptics & ripple feedback on selection; optional long-press tooltips.

• Routing-ready: bind onTap to your navigation (GoRouter, AutoRoute, custom).

• Accessibility & RTL: large hit targets, semantic roles, high-contrast states, and localization support.
