# 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() {
  if (!isUnbound) {
    throw FidlStateException(
        "AsyncProxyController<${$interfaceName}> isn't unbound");
  }

  ChannelPair pair = ChannelPair();
  if (pair.status != ZX.OK) {
    throw FidlError(
        "AsyncProxyController<${$interfaceName}> couldn't create channel: ${getStringForStatus(pair.status)}");
  }
  _reader.bind(pair.first!);
  state = InterfaceState.bound;

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