# open method




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



- @override

void open
(dynamic flags, int mode, String path, [InterfaceRequest](../../package-fidl_fidl/InterfaceRequest-class.md) request, [dynamic parentFlags])

_<span class="feature override">override</span>_



<p>This function is called from <code>fidl_fuchsia_io.Directory#open</code>.
This function parses path and opens correct node.</p>
<p>Vnode provides a simplified implementation for non-directory types.
Behavior:
For directory types, it will throw UnimplementedError error.
For non empty path it will fail with <code>ERR_NOT_DIR</code>.</p>



## Implementation

```dart
@override
void open(
    OpenFlags flags, int mode, String path, InterfaceRequest<Node> request,
    [OpenFlags? parentFlags]) {
  if (_isClosed) {
    sendErrorEvent(flags, ZX.ERR_NOT_SUPPORTED, request);
    return;
  }

  final status = _validateFlags(flags);
  if (status != ZX.OK) {
    sendErrorEvent(flags, status, request);
    return;
  }

  // Forward the reqeuest on to the remote directory
  _proxy.open(flags, mode, path, request);
}
```
