  final List<String> usingDirectives = <String>[
    'flutter::BasicMessageChannel',
    'flutter::CustomEncodableValue',
    'flutter::EncodableList',
    'flutter::EncodableMap',
    'flutter::EncodableValue',
  ];
  usingDirectives.sort();
  for (final String using in usingDirectives) {
    indent.writeln('using $using;');
  }
  indent.newln();
  _writeFunctionDefinition(indent, 'CreateConnectionError',
      returnType: 'FlutterError',
      parameters: <String>['const std::string channel_name'], body: () {
    indent.format('''
