toLowerCamelCase method

Implementation

String toLowerCamelCase() {
  if (isEmpty) return '';

  // If the string is already PascalCase (no delimiters, starts uppercase)
  if (!contains(RegExp(r'[_\s-]')) && this[0].toUpperCase() == this[0]) {
    return this[0].toLowerCase() + substring(1);
  }

  final words = trim()
      .split(RegExp(r'[_\s-]+')) // split by space, underscore, hyphen
      .where((w) => w.isNotEmpty)
      .toList();

  if (words.isEmpty) return '';

  final firstWord = words.first.toLowerCase();
  final rest = words.skip(1).map((word) {
    final lower = word.toLowerCase();
    return lower[0].toUpperCase() + lower.substring(1);
  }).join();

  return firstWord + rest;
