validate method

  1. @override
bool validate(
  1. T value,
  2. Map<String, FormFieldState> fields
)
override

Validates the given value against the validation rule.

  • value: The value to be validated.
  • fields: A map of form field states for cross-field validation.

Returns true if the validation passes, false otherwise.

Implementation

@override
bool validate(T value, Map<String, FormFieldState> fields) {
  if (!fields.containsKey(otherField)) {
    throw ArgumentError('Field $otherField does not exist');
  }
  return value == fields[otherField]!.value;
}
