patchbayJsonEquals function

bool patchbayJsonEquals(Object? left, Object? right)

Structural equality for two decoded JSON values.

== on maps and lists is identity in Dart, so a declared {"a": 1} would never match an equal object the App just built. Numbers compare by value, so a JSON 1 matches a 1.0 the consumer computed — the wire cannot tell an operator which one they typed.

Implementation

bool patchbayJsonEquals(Object? left, Object? right) {
  if (left is Map<Object?, Object?>) {
    if (right is! Map<Object?, Object?> || left.length != right.length) {
      return false;
    }
    for (final Object? key in left.keys) {
      if (!right.containsKey(key)) return false;
      if (!patchbayJsonEquals(left[key], right[key])) return false;
    }
    return true;
  }
  if (left is List<Object?>) {
    if (right is! List<Object?> || left.length != right.length) return false;
    for (var index = 0; index < left.length; index += 1) {
      if (!patchbayJsonEquals(left[index], right[index])) return false;
    }
    return true;
  }
  return left == right;
