## 🔴 Critical Issues (must fix before merge)

### 1. [Security] API key hardcoded
- **File**: `lib/core/config.dart:15`
- **Problem**: API key directly included in source code
- **Impact**: Security vulnerability, key exposure risk
- **Fix**: Use environment variables via Envied

 ### 2. [Testing] UseCase tests missing
- **File**: `test/domain/usecase/`
- **Problem**: No tests for core business logic
- **Impact**: Risk of regression bugs
- **Fix**: Add unit tests per UseCase

---

## 🟡 Improvements (recommended fixes)

### 1. [Performance] Image cache size needs to be specified
- **File**: `lib/presentation/widget/product_card.dart:42`
- **Current code**:

- **Recommended code**:

 ### 2. [State Management] BlocBuilder optimization
- **File**: `lib/presentation/page/home_page.dart:78`
- **Current code**:

- **Recommended code**:

## 🟢 Suggestions (optional improvements)

### 1. [Readability] Variable name improvement suggestion
- `data` → `userProfile`
- `list` → `productItems`
- `result` → `authResult`

### 2. [Structure] Widget extraction suggestion
- `_buildHeader()` → Extract to `HomeHeader` widget
- Improves reusability and testability

---

## ❓ Questions

1. `auth_bloc.dart:45` - What is the intent of this exception handling logic?
2. `user_repository.dart:89` - Is there a reason the cache expiration time is 5 minutes?

---

## Conclusion

Overall good code. Can merge after fixing 2 Critical Issues.

# Quick Review: [filename]

**Result**: ✅ Approved with comments

## Key Feedback

1. **[Performance]** Adding image cache size recommended
   - `product_card.dart:42`

2. **[Readability]** Variable name `data` → `userProfile` recommended

### Review Items

| Item | Status | Notes |
|------|--------|-------|
| Clean Architecture layer separation | ✅ | |
| UseCase pattern usage | ✅ | |
| Repository interface separation | ⚠️ | Partially missing |
| Feature module independence | ✅ | |

### Detailed Feedback

#### Repository Interface Separation (⚠️)

**Current State**:
- `CartRepository` directly implemented without interface

**Recommended Change**:
1. Create `ICartRepository` interface
2. Place interface in Domain layer
3. Implement in Data layer

🔴 **[Required]** Security vulnerability

**Location**: `lib/core/config.dart:15`

**Problem**: API key is hardcoded.

**Fix**:

 Cannot merge until this issue is resolved.

🟡 **[Improvement]** Performance optimization

**Location**: `lib/presentation/widget/product_card.dart:42`

**Current code**:

 **Recommended code**:

 Specifying image cache size reduces memory usage.

🟢 **[Suggestion]** Variable name improvement

**Location**: `lib/presentation/bloc/home_bloc.dart:25`

Changing variable name `data` to `userProfile` would improve readability.

---

❓ **[Question]** Exception handling intent

**Location**: `lib/data/repository/auth_repository.dart:45`

Is there a reason this try-catch block ignores all exceptions?

✨ **Nice!** Clean state management

**Location**: `lib/presentation/bloc/cart_bloc.dart`

State management using Freezed and Union Types is very clean.
The loading/error/success state separation is especially well done!
