# 📱 Panduan Mengubah Logo/Icon APK

## ✅ Cara 1: Otomatis dengan flutter_launcher_icons (SUDAH DISETUP)

### Langkah 1: Install Package
Saya sudah menambahkan `flutter_launcher_icons` ke `pubspec.yaml`. Sekarang jalankan:

```bash
flutter pub get
```

### Langkah 2: Siapkan Logo
**Requirement:**
- Format: PNG
- Ukuran: **1024x1024 px** (recommended) atau minimal 512x512 px
- Background: Transparent atau solid color
- File: `assets/images/logo_apsgo.png` (sudah ada)

**Jika ingin ganti logo:**
1. Siapkan file PNG 1024x1024 px
2. Replace file `assets/images/logo_apsgo.png`

### Langkah 3: Generate Icon
Jalankan command ini di terminal:

```bash
flutter pub run flutter_launcher_icons
```

### Langkah 4: Verify
Check folder ini, icon seharusnya sudah ter-generate:
- `android/app/src/main/res/mipmap-hdpi/ic_launcher.png`
- `android/app/src/main/res/mipmap-mdpi/ic_launcher.png`
- `android/app/src/main/res/mipmap-xhdpi/ic_launcher.png`
- `android/app/src/main/res/mipmap-xxhdpi/ic_launcher.png`
- `android/app/src/main/res/mipmap-xxxhdpi/ic_launcher.png`

### Langkah 5: Build APK
```bash
flutter build apk --release
```

## 🎨 Cara 2: Manual (Advanced)

Jika cara otomatis tidak berhasil, gunakan cara manual:

### Langkah 1: Prepare Icon dengan Berbagai Ukuran

| Resolusi | Ukuran | Folder |
|----------|--------|--------|
| MDPI | 48x48 px | `mipmap-mdpi/` |
| HDPI | 72x72 px | `mipmap-hdpi/` |
| XHDPI | 96x96 px | `mipmap-xhdpi/` |
| XXHDPI | 144x144 px | `mipmap-xxhdpi/` |
| XXXHDPI | 192x192 px | `mipmap-xxxhdpi/` |

### Langkah 2: Replace File

Replace semua file `ic_launcher.png` di folder berikut:
```
android/app/src/main/res/mipmap-hdpi/ic_launcher.png
android/app/src/main/res/mipmap-mdpi/ic_launcher.png
android/app/src/main/res/mipmap-xhdpi/ic_launcher.png
android/app/src/main/res/mipmap-xxhdpi/ic_launcher.png
android/app/src/main/res/mipmap-xxxhdpi/ic_launcher.png
```

### Langkah 3: Build APK
```bash
flutter build apk --release
```

## 🌟 Adaptive Icon (Android 8.0+) - Optional

Untuk icon yang lebih modern dengan adaptive background:

### Update pubspec.yaml:
```yaml
flutter_launcher_icons:
  android: true
  ios: false
  image_path: "assets/images/logo_apsgo.png"
  adaptive_icon_background: "#4CAF50"  # Warna background
  adaptive_icon_foreground: "assets/images/logo_apsgo.png"
```

### Generate:
```bash
flutter pub run flutter_launcher_icons
```
