# request method








[InterfaceRequest](../../package-fidl_fidl/InterfaceRequest-class.md)<T> request
()





<p>Creates an interface request whose peer is bound to this interface proxy.</p>
<p>Creates a channel pair, binds one of the channels to this object, and
returns the other channel. Calls to the proxy will be encoded as messages
and sent to the returned channel.</p>
<p>The proxy must not already have been bound.</p>



## Implementation

```dart
InterfaceRequest<T> request() {
  assert(!isBound);
  ChannelPair pair = ChannelPair();
  assert(pair.status == ZX.OK);
  _reader.bind(pair.first!);

  _boundCompleter.complete();
  final callback = onBind;
  if (callback != null) {
    callback();
  }

  return InterfaceRequest<T>(pair.second);
}
```
