Delete a message (optimistic update).

Implementation

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

  final removedMessage = _state.messages[index];
  final originalMessages = List<InboxMessage>.from(_state.messages);
  final originalCount = _state.unreadCount;

  // Optimistic update
  final updatedMessages = List<InboxMessage>.from(_state.messages)
    ..removeAt(index);
  final newCount =
      removedMessage.read ? _state.unreadCount : (_state.unreadCount - 1).clamp(0, 999999);

  _state = _state.copyWith(
    messages: updatedMessages,
    unreadCount: newCount,
  );
  notifyListeners();
