# AsyncProxyController<T> constructor







AsyncProxyController<T>({String $serviceName, String $interfaceName})


<p>Creates proxy controller.</p>
<p>Proxy controllers are not typically created directly. Instead, you
typically obtain an <a href="../../package-fidl_fidl/AsyncProxyController-class.md">AsyncProxyController&lt;T&gt;</a> object as the <a href="../../package-fidl_fidl/AsyncProxy/ctrl.md">AsyncProxy&lt;T&gt;.ctrl</a>
property of a <code>TProxy</code> object.</p>



## Implementation

```dart
AsyncProxyController({this.$serviceName, this.$interfaceName}) {
  _reader
    ..onReadable = _handleReadable
    ..onError = _handleError;
  whenClosed.then((_) {
    for (final Completer completer in _completerMap.values) {
      if (!completer.isCompleted) {
        completer.completeError(FidlError(
            'AsyncProxyController<${$interfaceName}> connection closed'));
      }
    }
    _completerMap.clear();
  }, onError: (_) {
    // Ignore errors.
  });
}
```
