📦 Installation #

Add to your pubspec.yaml:

dependencies:
  voo_navigation: ^0.0.6
  # Or for local development:
  # voo_navigation:
  #   path: packages/ui/voo_navigation

🚀 Quick Start #

With go_router (Recommended) #

import 'package:go_router/go_router.dart';
import 'package:voo_navigation/voo_navigation.dart';

// 1. Define your router with StatefulShellRoute
final router = GoRouter(
  initialLocation: '/home',
  routes: [
    StatefulShellRoute.indexedStack(
      builder: (context, state, navigationShell) {
        // Pass the navigation shell to your scaffold
        return ScaffoldWithNavigation(
          navigationShell: navigationShell,
        );
      },
      branches: [
        StatefulShellBranch(
          routes: [
            GoRoute(
              path: '/home',
              builder: (context, state) => HomePage(),
              routes: [
                // Nested routes
                GoRoute(
                  path: 'details',
                  builder: (context, state) => HomeDetailsPage(),
                ),
              ],
            ),
          ],
        ),
        StatefulShellBranch(
          routes: [
            GoRoute(
              path: '/profile',
              builder: (context, state) => ProfilePage(),
            ),
          ],
        ),
      ],
    ),
  ],
);

// 2. Create your navigation scaffold
class ScaffoldWithNavigation extends StatelessWidget {
  final StatefulNavigationShell navigationShell;

  const ScaffoldWithNavigation({required this.navigationShell});

  @override
  Widget build(BuildContext context) {
    final items = [
      VooNavigationItem(
        id: 'home',
        label: 'Home',
        icon: Icons.home_outlined,
        selectedIcon: Icons.home,
        badgeCount: 3,
      ),
      VooNavigationItem(
        id: 'profile',
        label: 'Profile',
        icon: Icons.person_outline,
        selectedIcon: Icons.person,
      ),
    ];

    return VooAdaptiveScaffold(
      config: VooNavigationConfig(
        items: items,
        selectedId: items[navigationShell.currentIndex].id,
        onNavigationItemSelected: (itemId) {
          final index = items.indexWhere((item) => item.id == itemId);
          if (index != -1) {
            navigationShell.goBranch(index);
          }
        },
      ),
      body: navigationShell,  // Pass the shell as body
    );
  }
}

// 3. Use with MaterialApp.router
MaterialApp.router(
  routerConfig: router,
)

)

Configuration Options #

VooNavigationConfig(
  // Core
  items: [...],
  selectedId: 'current_id',
  
  // Behavior
  isAdaptive: true,           // Auto-adapt to screen size
  forcedNavigationType: NavigationType.rail,  // Override adaptive

  enableAnimations: true,
  animationDuration: Duration(milliseconds: 300),
  animationCurve: Curves.easeInOut,
  
  // Appearance
  railLabelType: NavigationRailLabelType.selected,
  useExtendedRail: true,
  showNavigationRailDivider: true,
  centerAppBarTitle: false,
  
  // Colors (v0.0.5 defaults to modern dark theme)

)

📱 Responsive Breakpoints #

The package uses Material 3 breakpoints by default:

You can customize breakpoints:

VooNavigationConfig(
  breakpoints: [
    VooBreakpoint(
      minWidth: 0,
      maxWidth: 500,
      navigationType: VooNavigationType.bottomNavigation,
      columns: 4,
      margin: EdgeInsets.all(16),
      gutter: 8,
    ),
    // Add more custom breakpoints
  ],
)

🎨 Theming #

The package fully integrates with your app's theme:

MaterialApp(
  theme: ThemeData(
    colorScheme: ColorScheme.fromSeed(seedColor: Colors.blue),
    useMaterial3: true,
    navigationBarTheme: NavigationBarThemeData(...),
    navigationRailTheme: NavigationRailThemeData(...),
    drawerTheme: DrawerThemeData(...),
  ),
)

🔔 Badges & Notifications #

Show badges on navigation items:

// Count badge
VooNavigationItem(
  badgeCount: 10,  // Shows "10"
)

// Custom text badge
VooNavigationItem(
  badgeText: 'NEW',
  badgeColor: Colors.orange,
)

// Simple dot indicator
VooNavigationItem(
  showDot: true,
  badgeColor: Colors.red,
)

📂 Sections & Groups #

Organize items into sections:

VooNavigationItem.section(
  label: 'Communication',
  children: [
    VooNavigationItem(id: 'messages', ...),
    VooNavigationItem(id: 'email', ...),
  ],
  isExpanded: true,
)

🎭 Animations #

All transitions are animated by default (enhanced in v0.0.5):

• Navigation type changes with smooth transitions
• Item selection with AnimatedSwitcher (200ms)
• Badge updates with scale animations
• Drawer/rail expansion with easing curves
• FAB position changes with Material 3 motion
• Icon transitions between selected/unselected states
• Hover effects with subtle opacity changes (5% overlay)

Control animations:

VooNavigationConfig(
  enableAnimations: false,  // Disable all animations
  animationDuration: Duration(milliseconds: 500),
  animationCurve: Curves.elasticOut,
)
