# matchesFeature method

1. @override

bool matchesFeature(

1. List <XMLNode> features

)
override

Returns true if a feature in `features`, which are the children of the <stream:features /> nonza, can be negotiated. Otherwise, returns false.

## Implementation

    @override
    bool matchesFeature(List<XMLNode> features) {
      // Is SASL advertised?
      final mechanisms = features.firstWhereOrNull(
        (XMLNode feature) => feature.attributes['xmlns'] == saslXmlns,
      );
      if (mechanisms == null) return false;

      // Is SASL PLAIN advertised?
      return mechanisms.children.firstWhereOrNull(
            (XMLNode mechanism) => mechanism.text == mechanismName,
          ) !=
          null;
    }
