createValidIdentifier static method

String createValidIdentifier(String name)

Creates a valid Dart identifier from a given name

Replaces invalid characters with underscores, ensures it doesn't start with a number, and converts to camelCase format.

Implementation

static String createValidIdentifier(String name) {
  // Replace invalid characters with underscores
  String cleaned = name.replaceAll(RegExp(r'[^a-zA-Z0-9_]'), '_');

  // Ensure it doesn't start with a number
  if (cleaned.isNotEmpty && RegExp(r'^[0-9]').hasMatch(cleaned)) {
    cleaned = '_$cleaned';
  }

  // Convert to camelCase
  final parts = cleaned.split('_').where((part) => part.isNotEmpty).toList();
  if (parts.isEmpty) return '_unnamed';

  return parts.first.toLowerCase() +
      parts
          .skip(1)
          .map(
            (part) => part.isEmpty
                ? ''
                : part[0].toUpperCase() + part.substring(1).toLowerCase(),
          )
          .join();
}
