I think the TimelineView in chapter 15 is not working quite right. It’s not updating the flight list. Maybe we have to use onChange and monitor the context.date and do some kind of load of the flights data the way refreshable() works.
Can you provide a bit more detail on what you’re seeing? When is the list not updating?
When you have TimelineView set to update every minute, its not updating the flight status so the times, like “6 minutes ago” are not updating. When you drag to refresh, the refreshable modifier is updating the flight status and so the relative time strings change.
