| StackTrace? stackTrace | |
| _<span class="feature inherited">inherited</span>_ | |
| <p>The stack trace at the point where this error was first thrown.</p> | |
| <p>Classes which <em>extend</em> <code>Error</code> will automatically have a stack | |
| trace filled in the first time they are thrown by a <code>throw</code> | |
| expression.</p> | |
| ## Implementation | |
| ```dart | |
| external StackTrace? get stackTrace; | |
| ``` | |
