notifications constant
String
const notifications
Durable notification delivery queue + inbox. payload is the
canonical AtNotification JSON; the other columns are indexed
extracts for the three query shapes (since-time monitor scans,
startup re-enqueue of queued, expiry sweep).
Implementation
static const String notifications = '''
CREATE TABLE IF NOT EXISTS notifications (
id TEXT PRIMARY KEY NOT NULL,
payload TEXT NOT NULL,
notification_datetime INTEGER NOT NULL,
type TEXT NOT NULL,
status TEXT NOT NULL,
expires_at INTEGER
) WITHOUT ROWID;
''';
