# getAttributeNS method Null safety

String? getAttributeNS (

1. String? namespaceURI,
2. String name

)

## Implementation

    @pragma('dart2js:tryInline')
    String? getAttributeNS(String? namespaceURI, String name) {
      // TODO(41258): Delete this assertion after forcing strong mode.
      // Protect [name] against string conversion to "null" or "undefined".
      // [namespaceURI] does not need protecting, both `null` and `undefined` map to `null`.
      assert(name != null, 'Attribute name cannot be null');
      return _getAttributeNS(namespaceURI, name);
    }
