fix: AlignComponent set child (remove compare)

[denisgl7]

At the moment, I have removed the additional check, because an object deleted outside its parent may not be checked and the reference is not reset in the onChildrenChanged method

Can you explain more why this needs to be removed? Even if a child is removed with removeFromParent it should go through this lifecycle method.

[denisgl7]

  @mustCallSuper
  @override
  void onChildrenChanged(Component child, ChildrenChangeType type) {
    print('onChildrenChanged: $child, $type');
    if (_child?.parent != this) {
      this.child = null;
    }
  }

I have never seen a print of this method

Of course you need to understand the problem. But problem is definitely not on the side of this component. Unfortunately, I don’t yet know all the intricacies of the framework. Perhaps the method is not called because we can add a child to the same parent.

I would also like to add that these changes to the class will not affect performance, but will make this component work well.

[spydon]

We should open a separate issue about this if it doesn't work, I'll merge this meanwhile.

Agree
