# ComponentContext.create constructor




    *[<Null safety>](https://dart.dev/null-safety)*



ComponentContext.create()


<p>Creates the component context. Users need to make sure that they call
serve after they have finished adding all their public services.</p>
<p>Note: ComponentContext can only be constructed once.</p>
<p>Example:</p>
<pre class="language-dart"><code>Future&lt;void&gt; main() async {
  final context = ComponentContext.create();
  ...
  await doAsyncSetup();
  ...
  context.outgoing.serveFromStartupInfo();
}
</code></pre>



## Implementation

```dart
factory ComponentContext.create() {
  if (_componentContext != null) {
    throw Exception(
        'Attempted to construct ComponentContext multiple times. Ensure that the existing ComponentContext is reused instead of constructing multiple instances.');
  }
  return _componentContext = ComponentContext(
    svc: Platform.isFuchsia ? Incoming.fromSvcPath() : Incoming(),
    outgoing: Outgoing(),
  );
}
```
