visitRecordType method

@override StringSink visitRecordType(RecordType spec, [ StringSink? output ])

Implementation

@override

  final out = (output ??= StringBuffer())..write('(');
  visitAll<Reference>(spec.positionalFieldTypes, out, (spec) {
    spec.accept(this, out);
  });

    if (spec.positionalFieldTypes.isNotEmpty) {
      out.write(', ');
    }
    out.write('{');
    visitAll<MapEntry<String, Reference>>(spec.namedFieldTypes.entries, out,
        (entry) {
      entry.value.accept(this, out);
      out.write(' ${entry.key}');
    });
    out.write('}');
  } else if (spec.positionalFieldTypes.length == 1) {
    out.write(',');
  }
  out.write(')');
  // It doesn't really make sense to use records without
  // `_useNullSafetySyntax`, but since code_builder is generally very
  // permissive, follow it here too.
  if (_useNullSafetySyntax && (spec.isNullable ?? false)) {
    out.write('?');
  }
  return out;
