handle method

@override Future<void> handle(List<String> args)

Called automatically before executing the command. You can override to do pre-validation or setup.

Implementation

@override
Future<void> handle(List<String> args) async {
  final input = argResults?['name'] as String?;
  if (input == null || input.trim().isEmpty) {
    logger
        .error('❌ Usage: khadem make:exception --name=InvalidOrderException');
    exitCode = 1;
    return;
  }

  final parts = CliNaming.splitFolderAndName(input);
  final folder = parts.folder;
  final rawName = parts.name;
  final className = CliNaming.ensureSuffix(
    CliNaming.toPascalCase(rawName),
    'Exception',
  );
  final fileName =
      '${CliNaming.toSnakeCase(className.replaceAll('Exception', ''))}_exception.dart';

  final relativePath = folder.isEmpty
      ? 'lib/app/exceptions/$fileName'
      : 'lib/app/exceptions/$folder/$fileName';

  final file = File(relativePath);
  if (await file.exists()) {
    logger.error('❌ Exception "$fileName" already exists at "$relativePath"');
    exitCode = 1;
    return;
  }

  await file.create(recursive: true);
  await file.writeAsString(_stub(className));

  logger.info('✅ Exception "$className" created at "$relativePath"');
  exitCode = 0;
}
