group method
Groups notifications the way the official Bluesky social-app does.
By default uses NotificationsGrouperConfig.official (six grouped
reasons, a 48h window, one entry per author, follow-back separation,
unread-if-any).
Pass config to customize grouping — for example
NotificationsGrouperConfig.lenient for the legacy behavior from
bluesky <= 2.x, or a fully custom NotificationsGrouperConfig. Pass
by to additionally pre-bucket notifications by UTC wall-clock time
before
grouping.
See NotificationsGrouper.group for the full grouping rules.
Implementation
GroupedNotifications group({
final GroupBy? by,
final NotificationsGrouperConfig? config,
}) {
final grouper = config == null
? const NotificationsGrouper()
: NotificationsGrouper(config: config);
return grouper.group(this, by: by);
}
