Pages/StreamPage/detection_status library

Classes

DetectionStatus: What ObservANT's /healthz says: its name, whether and when a cat was in view, and its visits.
DetectionStatusLine: ObservANT's name and its cat, polled from /healthz; with no ObservANT behind the page, fallbackName alone.
Visit: One visit from /healthz's detection.recent: when it arrived, how long it stayed once it had left, and as what.

arrivalPicture(String url, String label) → dynamic: The arrival picture at url, 240 px wide: the previous one until the next loads, nothing on an error.
detectionLine(dynamic l10n, DetectionStatus status, DateTime now, String locale) → (dynamic, dynamic, String): What status says about the cat in one line, with its icon and colour.
formatLastSeen(DateTime when, DateTime now, String locale) → String: 14:32 for today, Oct 11 14:32 for an earlier day, in locale.
stayMinutes(Duration stayed) → String: A stay in whole minutes, <1 below one.
visitText(dynamic l10n, Visit visit, DateTime now, String locale, {bool named = false}) → String: One visit as the status line lists it: 14:32 (3 min), or the time alone while it goes on; named, what came first.
