Implementation

String generateMessage(dynamic content) {
  if (content is String) {
    return content;
  }
  if (content is List && content.isNotEmpty) {
    return content.join('\n');
  }
  if (content is Map) {
    if (content.containsKey('errors')) {
      final errors = content['errors'];
      if (errors is String) {
        return errors;
      }
      if (errors is List && errors.isNotEmpty) {
        return errors.join('\n');
      }
      if (errors is Map && errors.values.isNotEmpty) {
        return errors.values.join('\n');
      }
    }
    if (content.containsKey('message') && content['message'] is String) {
      return content['message'];
    }
  }
  return '...';
