+/// A button in an action sheet.
+///
+/// When built from server data, the action sheet ignores changes in that data;
+/// we intentionally don't live-update the buttons on events.
+/// If a button's label, action, or position changes suddenly,
+/// it can be confusing and make the on-tap behavior unexpected.
+/// Better to let the user decide to tap
+/// based on information that's comfortably in their working memory,
+/// even if we sometimes have to explain (where we handle the tap)
+/// that that information has changed and they need to decide again.
