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) {
  if (value is! String || _fn == null) return [];
  if (!_fn(value)) {
    return [SchemaViolation(path: path, message: 'must be a valid $format')];
  }
  return [];
}
