# allowsAttribute method Null safety

bool allowsAttribute (

1. Element element,
2. String attributeName,
3. String value

)
override

Returns true if the attribute is allowed.

The attributeName parameter will always be in lowercase.

See allowsElement for format of tagName.

## Implementation

    bool allowsAttribute(Element element, String attributeName, String value) {
      return _validators
          .any((v) => v.allowsAttribute(element, attributeName, value));
    }
