A minimal icon-only bottom bar with a soft circular bubble behind the active tab. Clean, spacious, and distraction-free—perfect for apps that favor icons over labels (e.g., Home, Wallet, Analytics, Profile).

Functionality

• Bubble highlight for the selected tab with adjustable size, color, and opacity.

• Icon-only layout (optional labels toggle).

• Active/Inactive states with separate colors and alpha.

• Smooth animations on tab change (fade/scale/slide).

• Badges (dot/count) per tab for notifications.

• Routing ready: bind taps to go_router, auto_route, or custom flows.

• Safe-area aware; supports gesture insets and device notches.

• Theming: icon set, sizes, spacing, bubble radius, shadows, and backgrounds.

• Hide-on-scroll / auto-reveal behavior (optional).

• Haptics & ripple feedback for delightful interaction.

• State persistence to restore the last selected tab.

• Accessibility: large hit targets, semantic tab roles, high-contrast mode.

• Localization & RTL support for global apps.
