🚀 Quick Start #
The fastest way to add a drawer to your app:
1. Import the package #
// The barrel export lives at lib/main.dart
import 'package:nova_drawer/main.dart';
2. Create a controller #
final _controller = NovaDrawerController(
initialSelectedItemId: 'home',
);
3. Build the scaffold #
NovaDrawerScaffold(
controller: _controller,
appBar: AppBar(
title: const Text('My App'),
leading: IconButton(
icon: const Icon(Icons.menu),
onPressed: _controller.toggle,
),
),
drawer: NovaAppDrawer(
controller: _controller,
sections: [
NovaDrawerSectionData(
id: 'main',
title: 'Navigation',
items: [
NovaDrawerItem(
id: 'home',
title: 'Home',
icon: Icons.home_outlined,
selectedIcon: Icons.home,
route: '/home',
),
NovaDrawerItem(
id: 'profile',
title: 'Profile',
icon: Icons.person_outline,
selectedIcon: Icons.person,
badge: NovaDrawerItemBadge(count: 2),
),
],
),
],
header: NovaDrawerHeader(
config: NovaHeaderConfig(
variant: NovaHeaderVariant.classic,
profile: NovaHeaderUserProfile(
name: 'Jane Developer',
email: 'jane@example.com',
status: NovaUserStatus.online,
),
),
),
onItemTap: (item) {
Navigator.pushNamed(context, item.route ?? '/');
},
),
body: const Center(child: Text('Hello, NovaDrawer!')),
)

// Compact — icon-only row, ideal for mini/side drawers
NovaHeaderConfig(variant: NovaHeaderVariant.compact, profile: profile)
// Hero — large cover photo with magazine-style layout
NovaHeaderConfig(variant: NovaHeaderVariant.hero, profile: profile)
// Expanded — shows additional details and extra actions
NovaHeaderConfig(variant: NovaHeaderVariant.expanded, profile: profile)
// Animated gradient — cycling colour background
NovaHeaderConfig(
variant: NovaHeaderVariant.animatedGradient,
profile: profile,

🎛️ Controller API #
NovaDrawerController is a ChangeNotifier. Use it directly or provide it via NovaDrawerControllerProvider.
final controller = NovaDrawerController(
initialSelectedItemId: 'home',
initiallyOpen: false,
initiallyPinned: false, // useful for desktop default
);
// Open / close
controller.open();
controller.close();
controller.toggle();
// Pin (tablet/desktop persistent mode)
controller.pin();
controller.unpin();
controller.togglePin();
// Mini mode (icon-only sidebar)
controller.toMini();
controller.fromMini();
controller.toggleMini();
// Item selection
controller.selectItem('settings');
controller.selectByRoute('/settings/account'); // auto-expands parents
controller.clearSelection();
// Section expand/collapse
controller.expandSection('workspace');
controller.collapseSection('workspace');
controller.toggleSection('workspace');
// Nested item expand/collapse
controller.expandItem('projects');
controller.collapseItem('projects');
// Visibility / enable
controller.disableItem('logout');
controller.enableItem('logout');
controller.hideItem('admin');
controller.showItem('admin');
// Read state
print(controller.isOpen);
print(controller.isPinned);
print(controller.isMini);
print(controller.selectedItemId);
print(controller.isLoading);
Accessing the controller from descendants #
// Provide at the top:
NovaDrawerControllerProvider(
controller: _controller,
child: MyDrawerContent(),
)
// Read anywhere below:
final ctrl = NovaDrawerControllerProvider.of(context); // subscribes
final ctrl = NovaDrawerControllerProvider.read(context); // one-shot read
📱 Responsive Behavior #
| Device | Breakpoint | Default Mode |
|---|---|---|
| Mobile | < 600 px | Overlay (slides over content) |
| Tablet | 600–1024 px | Push (pushes content aside) |
| Desktop | > 1024 px | Side (persistent alongside content) |
Custom breakpoints #
NovaDrawerConfig(
breakpoints: const NovaDrawerBreakpoints(
mobile: 540,
tablet: 960,
),
)
Force a specific mode #
NovaDrawerConfig(displayMode: NovaDrawerDisplayMode.side) // Always persistent
NovaDrawerConfig(displayMode: NovaDrawerDisplayMode.overlay) // Always overlay
NovaDrawerConfig(displayMode: NovaDrawerDisplayMode.push) // Always push
NovaDrawerConfig(displayMode: NovaDrawerDisplayMode.mini) // Always mini
🎨 Theming #
Using the built-in theme #
NovaAppDrawer(
theme: const NovaDrawerTheme(
backgroundColor: Color(0xFF1E1E2E),
selectedItemColor: Color(0xFF89B4FA),
selectedItemBackgroundColor: Color(0x2089B4FA),

elevation: 8.0,
iconSize: 22.0,
itemHeight: 48.0,
expandedDrawerWidth: 280.0,
miniDrawerWidth: 64.0,
),
)
🔌 Slot-Based Builder APIs #
Override any part of the drawer with custom widgets:
NovaAppDrawer(
controller: _controller,
sections: _sections,
builders: NovaDrawerBuilders(
// Replace the default item rendering
itemBuilder: (context, item, isSelected) {
return AnimatedContainer(
duration: const Duration(milliseconds: 200),
decoration: BoxDecoration(
color: isSelected ? Colors.indigo.withOpacity(0.15) : Colors.transparent,
borderRadius: BorderRadius.circular(12),
),
child: ListTile(
leading: Icon(item.icon, color: isSelected ? Colors.indigo : null),
title: Text(item.title),
selected: isSelected,
),
);
},
// Custom section header
sectionBuilder: (context, section) {
return Padding(
padding: const EdgeInsets.symmetric(horizontal: 16, vertical: 8),
child: Text(
section.title?.toUpperCase() ?? '',
style: const TextStyle(
fontSize: 11,
fontWeight: FontWeight.w700,
letterSpacing: 1.5,
color: Colors.grey,
),
),
);
},
// Custom loading placeholder
loadingBuilder: (context) {
return const Center(
child: Padding(
padding: EdgeInsets.all(32),
child: CircularProgressIndicator(),
),
);
},
// Custom empty state
emptyStateBuilder: (context) {
return const Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Icon(Icons.inbox, size: 48, color: Colors.grey),
SizedBox(height: 8),
Text('No menu items', style: TextStyle(color: Colors.grey)),
],
),
);
},
// Custom error state
errorBuilder: (context, message, onRetry) {
return Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
const Icon(Icons.error_outline, color: Colors.red),
Text(message ?? 'Error'),
if (onRetry != null)
TextButton(onPressed: onRetry, child: const Text('Retry')),
],
),
);
},
// Custom footer
footerBuilder: (context) {
return const Padding(
padding: EdgeInsets.all(16),
child: Text('v1.0.0 · NovaDrawer', style: TextStyle(color: Colors.grey)),
);
},
),
)
🎆 Background Effects #
Animated gradient background #
NovaAppDrawer(
controller: _controller,
sections: _sections,
enableGradientBackground: true,
gradientColors: const [
Color(0xFF0F2027),
Color(0xFF203A43),
Color(0xFF2C5364),
],
)
Particle effects #
NovaAppDrawer(
controller: _controller,
sections: _sections,
enableParticleBackground: true,
particleColor: Colors.white,
particleCount: 30,
)
👆 Gesture Controls #
NovaDrawerConfig(
gestureConfig: const NovaDrawerGestureConfig(
enableSwipeToOpen: true, // Swipe from left edge to open
enableSwipeToClose: true, // Swipe drawer to close
swipeEdgeWidth: 24.0, // Detection edge width in logical px
swipeSensitivity: 0.5, // 0.0 = very sensitive, 1.0 = very resistant
enableDragHandle: true, // Show a visible drag handle
dragHandleColor: Colors.grey,
),
)
📐 Mini-Drawer Mode #
On tablet/desktop the drawer can collapse to a slim icon-only sidebar:
NovaDrawerConfig(
showMiniOnCollapse: true,
enableHoverExpand: true, // Expand on mouse hover
hoverExpandDelay: const Duration(milliseconds: 400),
)
// Programmatic control
_controller.toMini(); // Collapse to icon-only
_controller.fromMini(); // Expand back
_controller.toggleMini();
You can also use NovaMiniDrawer directly for a fixed sidebar:
NovaMiniDrawer(
controller: _controller,
items: iconOnlyItems,
width: 64,
)
🔗 Dynamic Data Loading #
The drawer shows a shimmer skeleton automatically while loading:
// Required imports for the dynamic loading example:
// import 'dart:convert';
// import 'package:http/http.dart' as http;
// Load items from an API
await _controller.loadItems(() async {
final response = await http.get(Uri.parse('https://api.example.com/menu'));
final data = (jsonDecode(response.body) as List).cast<Map<String, dynamic>>();
return data
.map((e) => NovaDrawerItem(
id: e['id'] as String,
title: e['title'] as String,
icon: Icons.circle,
))
.toList();
});
// Load sections from an API
await _controller.loadSections(() async {
// ... fetch and return List<NovaDrawerSectionData>
});
// Error state is stored in controller.errorMessage
if (_controller.errorMessage != null) {
print('Failed: ${_controller.errorMessage}');
}
🌐 RTL Support #
RTL is automatically inferred from Directionality. To force RTL:
Directionality(
textDirection: TextDirection.rtl,

♿ Accessibility #
NovaDrawer is built with accessibility first:
- Semantic labels for screen readers (TalkBack / VoiceOver)
- Focus traversal for keyboard and switch-access navigation
- Scalable text respects system font size settings
- Minimum touch targets (48 × 48 logical pixels)
- Drawer open/close announcements for screen readers
NovaDrawerConfig(
accessibilityConfig: const NovaDrawerAccessibilityConfig(
enableSemantics: true,
enableFocusTraversal: true,
enableScalableText: true,
minimumTouchTarget: 48.0,
announceOnOpen: true,
announceOnClose: true,
drawerLabel: 'Main navigation drawer',
closeButtonLabel: 'Close navigation drawer',
),
)
Custom semantic labels per item:
NovaDrawerItem(
id: 'inbox',
title: 'Inbox',
icon: Icons.inbox,
badge: const NovaDrawerItemBadge(count: 12),
semanticLabel: 'Inbox, 12 unread messages',
)
