[adaptive_scaffold] asserts that navigation rail items cannot be less than two items #110902
Description
The layout procedure responsible for the left navigation bar should resemble the Drawer APIs. If we set the number of NavigationDestinations on AdaptiveScaffold to some arbitrary number, we must have some comprehensive reason for why we do not allow an empty sidebar or one element in the sidebar.
Give a better error message whenever the rules of the NavigationDestination items are less than the number required.
