passes method

@override FutureOr<bool> passes(ValidationContext context)

Validates the value using the given context.

Returns true if valid, otherwise false.

Implementation

@override
FutureOr<bool> passes(ValidationContext context) {
  final args = context.parameters;
  final data = context.data;
  if (args.isEmpty) return false;

  final otherField = args[0];
  if (!data.containsKey(otherField)) {
    // If other field is missing, strictly it relies on how we define "different".
    // Laravel: "The given field must be different than the field under validation."
    // If other field is null/missing, and this field is not null, they are different.
    return true;
  }

  final otherValue = data[otherField];
  final value = context.value;

  return value != otherValue;
}
