## Working with Translations 🌐

This project relies on [flutter_localizations][flutter_localizations_link] and follows the [official internationalization guide for Flutter][internationalization_link].

### Adding Strings

1. To add a new localizable string, open the `app_en.arb` file at `lib/l10n/arb/app_en.arb`.

```arb
{
    "@@locale": "en",
    "counterAppBarTitle": "Counter",
    "@counterAppBarTitle": {
        "description": "Text shown in the AppBar of the Counter Page"
    }
}
```

2. Then add a new key/value and description

```arb
{
    "@@locale": "en",
    "counterAppBarTitle": "Counter",
    "@counterAppBarTitle": {
        "description": "Text shown in the AppBar of the Counter Page"
    },
    "helloWorld": "Hello World",
    "@helloWorld": {
        "description": "Hello World Text"
    }
}
```

3. Use the new string

```dart
import 'package:pinball/l10n/l10n.dart';

@override
Widget build(BuildContext context) {
  final l10n = context.l10n;
  return Text(l10n.helloWorld);
}
```

### Adding Translations

1. For each supported locale, add a new ARB file in `lib/l10n/arb`.

```
├── l10n
│   ├── arb
│   │   ├── app_en.arb
│   │   └── app_es.arb
```

2. Add the translated strings to each `.arb` file:

`app_en.arb`

```arb
{
    "@@locale": "en",
    "counterAppBarTitle": "Counter",
    "@counterAppBarTitle": {
        "description": "Text shown in the AppBar of the Counter Page"
    }
}
```

`app_es.arb`

```arb
{
    "@@locale": "es",
    "counterAppBarTitle": "Contador",
    "@counterAppBarTitle": {
        "description": "Texto mostrado en la AppBar de la página del contador"
    }
}
```
