String formatListWithAnd(List<String> items, { int limit = 0, })

Format a list of items with proper "and" conjunction.

Implementation

String formatListWithAnd(List<String> items, {int limit = 0}) {
  if (items.isEmpty) return '';

  final effectiveLimit = limit == 0 ? null : limit;

  // No limit or within limit: normal formatting
  if (effectiveLimit == null || items.length <= effectiveLimit) {
    if (items.length == 1) return items[0];
    if (items.length == 2) return '${items[0]} and ${items[1]}';

    final lastItem = items.last;
    final allButLast = items.sublist(0, items.length - 1);
    return '${allButLast.join(', ')}, and $lastItem';
  }

  // More items than limit: show first few + count
  final shown = items.sublist(0, effectiveLimit);
  final remaining = items.length - effectiveLimit;

  if (shown.length == 1) {
    return '${shown[0]} and $remaining more';
  }

  return '${shown.join(', ')}, and $remaining more';
}
