validate method

  1. @override
List<SchemaViolation> validate(
  1. dynamic value,
  2. String path
)
override

Validates value at path and returns every violation found.

path is a dot-notation string identifying the location of value within the document (e.g. 'address.city', '' for the root). Violations use path as their SchemaViolation.path.

Implementation

@override
List<SchemaViolation> validate(dynamic value, String path) {
  // Applies only to objects (maps); other types are silently skipped.
  if (value is! Map) return [];
  final violations = <SchemaViolation>[];
  if (minProperties != null && value.length < minProperties!) {
    violations.add(
      SchemaViolation(
        path: path,
        message: 'must have at least $minProperties properties',
      ),
    );
  }
  if (maxProperties != null && value.length > maxProperties!) {
    violations.add(
      SchemaViolation(
        path: path,
        message: 'must have at most $maxProperties properties',
      ),
    );
  }
  return violations;
}
