Features

• Three navigation modes — sidebar, icon rail, and tab bar with smooth animated transitions
• Morphing toggle button — cursor-tracking directional arrows with branding support (logo + label), powered by morphing_button
• Badge support — per-item badge counts with automatic aggregation on parent items
• Header branding — NavHeader with logo, title, and subtitle merged into the toggle button
• Page transitions — .withPages() constructor with fade, slide, and fadeThrough transitions via AnimatedSwitcher
• Keyboard shortcuts — press T to toggle navigation mode
• Hierarchical items — expand/collapse in sidebar, overlay dropdowns in tab bar
• Status panel — CPU/MEM/DISK progress bars with color-coded thresholds
• User info — avatar panel with optional onTap callback and hover feedback
• 4 built-in themes — Light, Dark, Ocean, Sunset (or build your own with NavToggleTheme.copyWith)
• Fully configurable — dimensions, durations, easing curves, colors, fonts, border radii
• Accessibility — respects MediaQuery.disableAnimations

Quick Start

import 'package:flutter_nav_toggle/flutter_nav_toggle.dart';

NavToggleScaffold(
  items: [
    NavItem(id: 'home', label: 'Home', icon: Icons.home_outlined),
    NavItem(id: 'settings', label: 'Settings', icon: Icons.settings_outlined, badge: 3),
  ],
  header: NavHeader(
    logo: Icon(Icons.dashboard, size: 24),
    title: 'My App',
  ),
  onItemSelected: (id) => print('Selected: $id'),
  child: Center(child: Text('Content')),
)

Hierarchical Items

NavItem(
  id: 'products',
  label: 'Products',
  icon: Icons.inventory_outlined,
  children: [
    NavItem(id: 'electronics', label: 'Electronics', icon: Icons.devices_outlined),
    NavItem(id: 'clothing', label: 'Clothing', icon: Icons.checkroom_outlined),
  ],
)

Parents expand/collapse in sidebar mode and open overlay dropdowns in tab bar mode.

Page Transitions

Use .withPages() to let the scaffold manage content switching with animated transitions:

NavToggleScaffold.withPages(
  items: items,
  pages: {
    'home': HomePage(),
    'settings': SettingsPage(),
  },
  pageTransitionType: PageTransitionType.fadeThrough,
  showPageHeader: true,
  enableKeyboardShortcuts: true,
)

Available transition types: fade, slideHorizontal, fadeThrough.

Theming

// Use a built-in preset
NavToggleScaffold(
  theme: const NavToggleTheme.ocean(),
  // ...
)

// Or customize
NavToggleScaffold(
  theme: const NavToggleTheme.dark().copyWith(
    sidebarWidth: 260,
    accent: Color(0xFFFF6B6B),
    collapseDuration: Duration(milliseconds: 300),
  ),
  // ...
)

Available presets: NavToggleTheme() (light), .dark(), .ocean(), .sunset()

System Status & User Info

NavToggleScaffold(
  systemStatus: SystemStatus(cpu: 0.42, memory: 0.67, disk: 0.55, warnings: 3),
  userInfo: UserInfo(name: 'Alice', role: 'Admin', onTap: () => print('User tapped')),
  // ...
)

Status displays as progress bars (sidebar) or compact chips (tab bar). User info shows as an avatar panel (sidebar) or chip (tab bar).
