A premium bottom navigation bar built for dark UIs with neon-accent styling and a subtle glass effect. The active tab expands into a pill highlight with icon + label, while the bar itself floats with layered shadows for depth. Fully configurable (36 params) and production-ready for FlutterFlow apps on iOS and Android.

• Neon/glass design: dark surface, soft blur feel, and luminous outline accent.

• Pill highlight state: active tab becomes a compact chip (icon + text).

• Floating depth: stacked shadows create a lifted, dock-like appearance.

• Smooth micro-interactions: color morph, scale, and slide animations with custom curves/duration.

• Badges ready: dot or numeric counters per tab (cart, inbox, alerts).

• Icon & label controls: sizes, weights, spacing, and per-tab visibility.

• Theme aware: easy color theming for neon accents (green by default).

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

• Haptics & ripple: tactile feedback with Material ripple on tap.

• Safe-area & gestures: works perfectly with notches and system gestures.

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

• Router friendly: simple onTap wiring to GoRouter/AutoRoute or Flow Actions.
