Returns a map of properties that differ between this object and another.

Implementation

@visibleForTesting
Map<String, String> getDiff(Equatable other) {
  final diff = <String, String>{};

  // Return empty map if no differences
  if (this == other) return diff;

  final otherProps = other.props;

  // Handle different props lengths
  if (props.length != otherProps.length) {
    diff['props.length'] =
        'this: ${props.length}, other: ${otherProps.length}';

    return diff;
  }

  final length = props.length;

  for (int i = 0; i < length; i++) {

    final unit2 = otherProps[i];

    final differences = compareObjects(unit1, unit2);

          'N/A';
      diff[propName] = differences.toString();
