A modern bottom navigation bar with a floating, rounded container and a capsule “pill” highlight for the active tab. The selected item expands into a chip with icon + label, while inactive items remain minimal for a clean, content-first look. Optimized for FlutterFlow projects and production apps on iOS and Android.

• Pill highlight state: active tab morphs into a filled chip with icon + text.

• Floating bar: soft multi-layer shadow, adjustable elevation and corner radius.

• Icon & label control: toggle labels, set sizes, weights, and spacing per tab.

• Per-tab styling: active/inactive colors, custom icons, background, and ripple.

• Smooth animations: scale/expand, color fade, and slide with custom curves/durations.

• Badges: dot or numeric counters on any item (cart, inbox, notifications).

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

• Safe-area aware: notch/gesture inset handling; works with transparent system bars.

• Haptics & feedback: optional tactile tap + material ripple.

• Routing-ready: wire onTap to GoRouter/AutoRoute or custom flow actions.

• Accessibility & RTL: large tap targets, semantic roles, high contrast, localization.
