### 3. Create Configuration File

Create a new file named `l10n.yaml` in the root directory of the Flutter project. Define the input directory, template file, and output file. The generated Dart files are written next to the `.arb` files in `arb-dir` unless `output-dir` is set:
```yaml
arb-dir: lib/l10n
template-arb-file: app_en.arb
output-localization-file: app_localizations.dart
synthetic-package: true
```

Do not set `synthetic-package`. Synthetic packages were removed from Flutter, and `flutter gen-l10n` rejects the option.

### 4. Configure the App Entry Point
Import the generated localizations and the `flutter_localizations` library in your `main.dart`. Inject the delegates and supported locales into your `MaterialApp` or `CupertinoApp`.

```dart
import 'package:flutter_localizations/flutter_localizations.dart';
import 'package:flutter_gen/gen_l10n/app_localizations.dart'; // Adjust path if synthetic-package is false
import 'l10n/app_localizations.dart'; // Generated into arb-dir; adjust if output-dir is set

// ... inside build method
