prprompts-flutter-generator: Command for Claude Code

Flutter App Localization - One Command Setup

Automatically localize an existing Flutter app with Arabic-English (ar-en) support in one command.

Overview

This command will:

1. ✅ Scan your Flutter project for hardcoded strings
2. ✅ Generate ARB files (app_en.arb master, app_ar.arb translation)
3. ✅ Create l10n.yaml configuration
4. ✅ Update pubspec.yaml with dependencies
5. ✅ Generate comprehensive integration guide
6. ✅ Validate the entire setup

Step 1: Validate Flutter Project

Check that the current directory is a valid Flutter project:

• pubspec.yaml exists
• lib/ directory exists
• Contains .dart files

If not valid, show error message:

❌ Error: Not a Flutter project
Current directory: {current_dir}

Please cd to your Flutter project root directory and try again.

Step 2: Scan for Hardcoded Strings

Scan all .dart files in lib/ for hardcoded strings in:

• Text widgets: Text('Hello'), Text("Welcome")
• AppBar titles: AppBar(title: Text('Home'))
• TextField hints: TextField(hintText: 'Enter email')
• Button labels: ElevatedButton(child: Text('Submit'))
• Dialog messages: AlertDialog(title: Text('Error'))
• SnackBar messages: SnackBar(content: Text('Saved'))

Exclusions:

• Skip files using AppLocalizations.of(context)
• Skip comments and debug statements
• Skip generated files (*.g.dart, *.freezed.dart)
• Skip build/, .dart_tool/, generated/ directories

String Interpolation: Convert Dart string interpolation to ICU MessageFormat:

• "Hello $name" → "Hello {name}"
• "Total: ${cart.total}" → "Total: {total}"

Track:

• Total unique strings found
• Number of files scanned

Step 3: Generate ARB Files

Master Template (app_en.arb):

{
  "@@locale": "en",
  
  "keyName": "Original English string",
  "@keyName": {
    "description": "Context for translators",
    "placeholders": {
      "variableName": {
        "type": "String",
        "example": "John"
      }
    }
  }
}
