markSeen method
Convenience method for marking the messages from the specified sequence
as seen/read.
Specify the unchangedSinceModSequence
to limit the store action to elements that have not changed since the specified modification sequence. This is only supported when the server supports the CONDSTORE or QRESYNC capability
Compare the store method in case you need more control or want to change several flags.
Implementation
Future<void> markSeen(MessageSequence sequence,
{int? unchangedSinceModSequence}) {
return store(sequence, [MessageFlags.seen],
unchangedSinceModSequence: unchangedSinceModSequence);
}
