| *[<Null safety>](https://dart.dev/null-safety)* |
| |
| |
| |
| <p>A node which wraps a VMO that can be duplicated when opened.</p> |
| <p>Reads when opening a <a href="../package-fuchsia_vfs_vfs/VmoFile-class.md">VmoFile</a> as a file are buffered, and repeated reads |
| will obtain the same information unless the connection is closed between |
| reads. |
| A duplicate of the underlying VMO is exposed through <code>Node.Describe</code> when |
| <a href="../package-fuchsia_vfs_vfs/VmoSharingMode.md">VmoSharingMode</a> is <code>shareDuplicate</code>.</p> |
