# sendMessage method








void sendMessage
([OutgoingMessage](../../package-fidl_fidl/OutgoingMessage-class.md) response)





<p>Sends the given message over the bound channel.</p>
<p>If the channel is not bound, the handles inside the message are closed and
the message itself is discarded.</p>



## Implementation

```dart
void sendMessage(OutgoingMessage response) {
  if (!isBound) {
    response.closeHandles();
    return;
  }
  _reader.channel?.writeEtc(response.data, response.handleDispositions);
}
```
