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


<p>Sends the given messages over the bound channel.</p>
<p>Used by subclasses of <a href="../../package-fidl_fidl/Proxy-class.md">Proxy&lt;T&gt;</a> to send encoded messages.</p>


## Implementation

```dart
void sendMessage(OutgoingMessage message) {
  if (!_reader.isBound) {
    proxyError(FidlStateException(
        'AsyncProxyController<${$interfaceName}> is closed.'));
    return;
  }
  final int status =
      _reader.channel!.writeEtc(message.data, message.handleDispositions);
  if (status != ZX.OK) {
    proxyError(FidlError(
        'AsyncProxyController<${$interfaceName}> failed to write to channel: ${_reader.channel} (status: $status)'));
  }
}
```
