formatQueryKey function

String formatQueryKey(
  1. dynamic key
)

Formats a query key list into a human-readable string.

Each part is stringified; maps/lists are JSON-encoded. Parts are joined with ' › '.

Example: ['users', {'id': 1}] → 'users › {"id":1}'

Implementation

String formatQueryKey(dynamic key) {
  if (key is String && key.isEmpty) return '';
  final list = key is String ? jsonDecode(key) : key;

  if (list is! Iterable) return list.toString();

  return list.map((part) {
    if (part is Map || part is List) return jsonEncode(part);
    return part.toString();
  }).join('  ›  ');
}
