## 🎯 Implementation Guide

### Step 1: Update Dependencies
Your `pubspec.yaml` already includes all required packages:
- ✅ `shared_preferences: ^2.2.2`
- ✅ `fl_chart: ^0.66.0`
- ✅ `get: ^4.6.6`
- ✅ `flutter_screenutil: ^5.9.0`

### Step 2: Initialize Theme Controller
Already done in `main.dart`:
```dart
void main() {
  Get.put(ThemeController());
  runApp(const LuckyChitApp());
}
```

### Step 3: Use Components in Your App
All components are ready to use:

```dart
// Loading state
if (isLoading) {
  return const SkeletonDashboard();
}

// Empty state
if (items.isEmpty) {
  return EmptyStateWidget(
    type: EmptyStateType.noGroups,
    onActionPressed: () => createGroup(),
  );
}

// Notifications
SnackbarUtil.showSuccess('Operation successful!');

// Search & Filter
SearchFilterBar(
  onChanged: (query) => search(query),
  onFilterTap: () => showFilters(),
)

// Charts
MonthlyPaymentChart(data: paymentData)
```

## 💡 Tips & Best Practices

### 1. Always Show Loading States
```dart
// Bad
if (items.isEmpty) return Text('No data');

// Good
if (isLoading) return SkeletonDashboard();
if (items.isEmpty) return EmptyStateWidget(...);
```

### 2. Provide Clear Feedback
```dart
// Bad
await saveData();

// Good
SnackbarUtil.showLoading('Saving...');
await saveData();
SnackbarUtil.dismiss();
SnackbarUtil.showSuccess('Saved!');
```

### 3. Use Appropriate Colors
```dart
// Success action
SnackbarUtil.showSuccess('Payment completed');

// Destructive action
SnackbarUtil.showWarning('This will delete all data');

// Error
SnackbarUtil.showError('Failed to save');
```

### 4. Implement Search & Filter
```dart
// For any list with > 10 items, add search
SearchFilterBar(
  hintText: 'Search...',
  onChanged: (query) => filter(query),
  onFilterTap: () => showFilters(),
)
```

### 5. Show Data Insights
```dart
// Instead of just lists, add visualizations
MonthlyPaymentChart(data: payments)
PaymentDistributionChart(categories: categories)
```
