Code Review
This pull request adds a regression test to ensure that NavigationDrawer does not crash when rendered in a zero-sized area. The test itself is a good idea, but in its current form, it's not effective because it doesn't include a NavigationDrawerDestination, which is necessary to trigger the code path that was causing the original crash. I've suggested a change to make the test correctly cover the intended scenario.

This test is intended to prevent a crash in NavigationDrawer when it has zero area. The original crash, as described in issue #6537, occurred within the NavigationIndicator widget. This widget is only built when there's at least one NavigationDrawerDestination in the children list of the NavigationDrawer.
By providing an empty list (children: <Widget>[]), this test doesn't exercise the code path that caused the crash, making it ineffective as a regression test. To make this test correctly cover the scenario, you should add at least one NavigationDrawerDestination to the children list.
