# close method








void close
()





<p>Close the channel bound to the proxy.</p>
<p>The proxy must have previously been bound (e.g., using <a href="../../package-fidl_fidl/ProxyController/bind.md">bind</a>).</p>



## Implementation

```dart
void close() {
  if (isBound) {
    if (_pendingResponsesCount > 0) {
      proxyError('The proxy is closed.');
    }
    _reset();
    _reader.close();

    final callback = onClose;
    if (callback != null) {
      callback();
    }
  }
}
```
