compare method

int compare(
  1. Map<String, dynamic> a,
  2. Map<String, dynamic> b
)

Compares two data maps based on this sort order

Implementation

int compare(Map<String, dynamic> a, Map<String, dynamic> b) {
  final aValue = _getNestedValue(a, field);
  final bValue = _getNestedValue(b, field);

  // Handle null values (nulls last)
  if (aValue == null && bValue == null) return 0;
  if (aValue == null) return 1;
  if (bValue == null) return -1;

  final result = _compareValues(aValue, bValue);
  return descending ? -result : result;
}
