Future<void> markAsRead(String messageId)

Mark single message as read (optimistic update).

Implementation

Future<void> markAsRead(String messageId) async {
  if (!_initialized) return;

  // Find message
  final index = _state.messages.indexWhere((m) => m.id == messageId);
  if (index == -1) return;

  final message = _state.messages[index];
  if (message.read) return; // Already read

  // Snapshot for rollback
  final originalRead = message.read;
  final originalCount = _state.unreadCount;

  // Optimistic update
  message.read = true;
  _state = _state.copyWith(
    unreadCount: (_state.unreadCount - 1).clamp(0, 999999),
  );
  notifyListeners();

  try {
    await _client!.inboxMarkAsRead(messageId);
    await _persistState();
  } catch (e) {
    // Revert on failure
    message.read = originalRead;
    _state = _state.copyWith(unreadCount: originalCount);
    notifyListeners();
    debugPrint('Error marking message as read: $e');
