πŸ”§ Advanced Usage

🎨 Custom Theme System

// Create reusable theme configurations
class AppAlerts {
  // Success theme
  static void showSuccess(String title, String message) {
    CustomQuickAlert.success(
      title: title,
      message: message,
      backgroundColor: const Color(0xFFF0FDF4),
      titleColor: const Color(0xFF16A34A),
      messageColor: const Color(0xFF166534),
      confirmBtnColor: const Color(0xFF22C55E),
      customShadows: [
        BoxShadow(
          color: Colors.green.withValues(alpha: 0.1),
          blurRadius: 20,
          offset: const Offset(0, 8),
        ),
      ],
    );
  }

  // Error theme
  static void showError(String title, String message) {
    CustomQuickAlert.error(
      title: title,
      message: message,
      backgroundColor: const Color(0xFFFEF2F2),
      titleColor: const Color(0xFFDC2626),
      messageColor: const Color(0xFF991B1B),
      confirmBtnColor: const Color(0xFFEF4444),
      customShadows: [
        BoxShadow(
          color: Colors.red.withValues(alpha: 0.1),
          blurRadius: 20,
          offset: const Offset(0, 8),
        ),
      ],
    );
  }

  // Dark theme variant
  static void showDarkThemeAlert(String title, String message) {
    CustomQuickAlert.info(
      title: title,
      message: message,
      backgroundColor: const Color(0xFF1F2937),
      titleColor: const Color(0xFFF9FAFB),
      messageColor: const Color(0xFFD1D5DB),
      confirmBtnColor: const Color(0xFF3B82F6),
      confirmTextColor: Colors.white,
      borderRadius: 12.0,
    );
  }
}

🎯 Custom Lottie Animations

// Using custom Lottie animations
CustomQuickAlert.custom(
  title: 'Custom Animation',
  message: 'This alert uses a custom Lottie animation.',
  lottieAsset: 'assets/animations/my_custom_animation.json',
  confirmText: 'Awesome!',
  backgroundColor: Colors.purple.shade50,
  titleColor: Colors.purple.shade800,
  confirmBtnColor: Colors.purple.shade600,
);

// Custom animation with callbacks
CustomQuickAlert.custom(
  title: 'Achievement Unlocked!',
  message: 'You have completed all tasks.',
  lottieAsset: 'assets/animations/achievement.json',
  confirmText: 'Collect Reward',
  onConfirm: () {
    // Handle reward collection
    RewardService.collectReward();
  },
);

⚑ Performance Optimization

class AlertManager {
  static Timer? _debounceTimer;
  static final Queue<AlertConfig> _alertQueue = Queue<AlertConfig>();
  static bool _isShowingAlert = false;
  
  // Debounced alerts to prevent spam
  static void showDebouncedSuccess(String title, String message) {
    _debounceTimer?.cancel();
    _debounceTimer = Timer(const Duration(milliseconds: 300), () {
      CustomQuickAlert.success(title: title, message: message);
    });
  }
  
  // Queue management for multiple alerts
  static void queueAlert(AlertConfig config) {
    _alertQueue.add(config);
    _processQueue();
  }
  
  static void _processQueue() {
    if (_isShowingAlert || _alertQueue.isEmpty) return;
    
    _isShowingAlert = true;
    final config = _alertQueue.removeFirst();
    
    // Show alert and process next after completion
    config.show().then((_) {
      _isShowingAlert = false;
      _processQueue();
    });
  }

  // Memory cleanup
  static void dispose() {
    _debounceTimer?.cancel();
    _alertQueue.clear();
    _isShowingAlert = false;
  }
}

class AlertConfig {
  final String title;
  final String message;
  final QuickAlertType type;
  
  AlertConfig({required this.title, required this.message, required this.type});
  
  Future<void> show() async {
    switch (type) {
      case QuickAlertType.success:
        return CustomQuickAlert.success(title: title, message: message);
      case QuickAlertType.error:
        return CustomQuickAlert.error(title: title, message: message);
      // ... other types
    }
  }
}

πŸ“š Migration Guide

πŸ”„ Upgrading from v1.x to v2.x

πŸ“ Complete Migration Guide

🚨 Breaking Changes

Version 2.0 introduces a context-free API that eliminates the need for BuildContext.

πŸ“‹ Migration Steps

1. Update Dependencies

dependencies:
  custom_quick_alert: ^2.1.1  # Update version

2. Setup Navigator Key

// Add to main.dart
final GlobalKey<NavigatorState> navigatorKey = GlobalKey<NavigatorState>();

void main() {
  runApp(const MyApp());
  CustomQuickAlert.initialize(navigatorKey);
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      navigatorKey: navigatorKey, // Add this
      home: const HomePage(),
    );
  }
}

3. Update API Calls

Old API (v1.x) New API (v2.x)
QuickAlert.show(context: context, type: QuickAlertType.success) CustomQuickAlert.success()
QuickAlert.show(context: context, type: QuickAlertType.error) CustomQuickAlert.error()
QuickAlert.show(context: context, type: QuickAlertType.warning) CustomQuickAlert.warning()

Before (v1.x):

QuickAlert.show(
  context: context,
  type: QuickAlertType.success,
  title: 'Success!',
  text: 'Operation completed',
);

After (v2.x):

CustomQuickAlert.success(
  title: 'Success!',
  message: 'Operation completed',
);

πŸ”§ Parameter Changes

v1.x Parameter v2.x Parameter Notes
text message Renamed for clarity
context (removed) No longer needed
showAnimationContainer (removed) Simplified animation system

πŸ” Troubleshooting

πŸ› Common Issues & Solutions

Issue: Alert not showing

Cause: Navigator key not configured
Solution:

MaterialApp(
  navigatorKey: navigatorKey, // Ensure this is set
  // ... other properties
)

Issue: Animations not working

Cause: Missing Lottie assets
Solution:

flutter:
  assets:
    - assets/animations/

Issue: Custom colors not applying

Cause: Incorrect parameter usage
Solution:

CustomQuickAlert.success(
  backgroundColor: Colors.green.shade50,  // Dialog background
  titleColor: Colors.green.shade800,     // Title color
  messageColor: Colors.green.shade600,   // Message color
);

Issue: Memory leaks with loading alerts

Cause: Not dismissing loading alerts
Solution:

// Always dismiss loading alerts
CustomQuickAlert.loading(title: 'Loading...');
// ... async operation
CustomQuickAlert.dismiss(); // Important!

Issue: Multiple alerts showing at once

Cause: Rapid consecutive calls
Solution:

// Use debouncing or queue management
AlertManager.showDebouncedSuccess('Title', 'Message');
