A production-ready, fully themable sidebar for Flutter/FlutterFlow that adapts from a full menu to a compact icon rail. It supports nested routes, badges, user profile footer, and smooth expand/collapse animations. Built for dashboards and data-heavy apps, the sidebar stays route-aware, keyboard accessible, and RTL/localization ready.

Functionality

• Responsive modes: persistent, dismissible, overlay; auto-switches to mini rail on smaller screens with configurable breakpoints.

• Stateful navigation: highlights the active route, preserves open section state, optional breadcrumbs/top-bar sync.

• Nested items & sections: multi-level groups with headers, dividers, and optional badges/counters.

• Interactions: tap, hover, and keyboard focus; swipe/drag to open; optional scrim & backdrop blur.

• User area: avatar, name, role, and quick actions (logout/settings) anchored at the footer.

• Theming: custom widths (expanded/collapsed), icon/text styles, active/hover colors, elevation, radius, shadows, animation duration/curve.

• Accessibility: focus order, ARIA semantics, high-contrast mode, tooltips for collapsed icons.

• Internationalization: LTR/RTL support and dynamic labels.

• Performance: lazy list for long menus; smooth 60 fps transitions.

• State persistence: remembers last width/mode and expanded groups across sessions.

Use Cases

• Admin dashboards & internal tools (CRM, ERP, analytics).

• SaaS consoles and multitenant back-offices.

• E-commerce management (orders, products, customers).

• Education/LMS and content platforms.

• Project management, ticketing, and collaboration apps.

• Any app requiring scalable, discoverable multi-section navigation.
