A stylish bottom navigation bar with a curved “wave” notch that docks a centered circular hub. The active tab gets a vivid accent (e.g., Home), while the center hub floats above for a featured destination or action (Store). Perfect for e-commerce, marketplaces, and lifestyle apps where the middle tab should stand out.

Functionality

• 4–5 tabs with icon + optional label; active tab accent & dimmed inactives.

• Animated elevation & shadow on the center hub for depth.

• Badge support (counts/dots) on any tab.

• Hide-on-scroll and auto-reveal behaviors (optional).

• Theming: colors, gradients, corner radii, blur, and icon size/weights.

• Safe-area aware; works with translucent system bars.

• Haptics & ripple feedback on press (optional).

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

• Localization & RTL ready; adaptive labels (show/hide) for compact layouts.
