Icons still showing even if it's parent widget's height is zero in Flutter

if (height > 0) IconButton(icon: Icon(Icons.favorite_border), onPressed: () {},)

This code snippet verifies if the widget's height is greater than 0, and only then displays the IconButton widget. This ensures that the icon is only visible when the parent widget has a non-zero height. You may adjust the value compared to 0 (e.g., 10) to remove the icon.

clipBehavior: Clip.hardEdge

Another way to resolve this issue is to add `clipBehavior: Clip.hardEdge` to the parent Container. This property prevents the child widgets from overflowing outside the parent's boundaries. By setting it to `Clip.hardEdge`, you force the icons to be clipped at the parent's edges, ensuring they are hidden when the parent's height is zero.
