### 1. End-to-End Flutter CI/CD Workflow (`.github/workflows/flutter_ci.yml`) 🚀

```yaml
name: Flutter CI/CD

on:
  push:
    branches: [ master ]

jobs:
  test_and_analyze:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: subosito/flutter-action@v2
        with:
          flutter-version: '3.22.x'
          channel: 'stable'
          cache: true

- name: Install & Static Analysis
        run: |
          flutter pub get
          flutter analyze
          flutter test --coverage

build_android:
    needs: test_and_analyze
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: subosito/flutter-action@v2
        with: { flutter-version: '3.22.x' }
      - name: Build Android App Bundle (AAB)
        run: flutter build appbundle --release
```

### 3. Master Comparison Matrix

### 4. Interview Ke 3 Sawal Is Topic Se

1. **Flutter build versioning (`version: 1.0.0+42` in pubspec.yaml) CI me kaise increment hoti hai?** -> `--build-name=1.0.0 --build-number=${{ github.run_number }}` build arguments pass karke.
2. **Obfuscation build flag (`--obfuscate --split-debug-info`) kya karta hai?** -> Dart symbols aur method names ko scramble karta hai aur debug symbol maps ko alag directory me save karta hai (Protects proprietary IP).
3. **Android Keystore secret GitHub Actions me securely kaise pass hota hai?** -> Keystore file ko Base64 encode karke GitHub Secret me store karna aur CI runner par decode karke `key.properties` generate karna.
