### 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

## 💡 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)
|
|
```
|
