# ProxyController&lt;T> class


<p>The control plane for an interface proxy.</p>
<p>A proxy controller lets you operate on the local <a href="../package-fidl_fidl/Proxy-class.md">Proxy&lt;T&gt;</a> object itself
rather than send messages to the remote implementation of the proxy. For
example, you can <a href="../package-fidl_fidl/ProxyController/unbind.md">unbind</a> or <a href="../package-fidl_fidl/ProxyController/close.md">close</a> the proxy.</p>
<p>You typically obtain a <a href="../package-fidl_fidl/ProxyController-class.md">ProxyController&lt;T&gt;</a> object as the <a href="../package-fidl_fidl/Proxy/ctrl.md">Proxy&lt;T&gt;.ctrl</a>
property of a <code>TProxy</code> object.</p>
<p>Example:</p>
<pre class="language-dart"><code class="language-dart">FooProxy foo = new FooProxy();
fooProvider.getFoo(foo.ctrl.request());
</code></pre>
