Code Review
This pull request correctly addresses the issue where a Scaffold with primary: false would incorrectly include a status bar gesture detector. The change is simple and effective, wrapping the status bar logic in a condition that checks widget.primary. The accompanying tests are well-written, covering both the intended behavior and preventing potential regressions. I have one minor suggestion to fix a typo in a test description.

Drive-by nit: This can use an early return instead, to reduce the diff / indent?
if (!widget.primary) {
break;
}
_addIfNonNull(...);

Can you also add a paragraph explaining this to the document of [primary]?
