Issue with conditional visibility

Hello

I have a swipeable stack that contains a stack of two containers with text.

Structure:

1. Swipeable Stack

   1. Stack

      1. Container A 👁️

      2. Container B

I also have a Local Page State Variable "showFront" which is initialized as being True.

When I click anywhere on my swipeable stack, I invert the value of showFront so I can switch between showFront == True and showFront == False.

I have added a Textfield to my Page as well that is displaying the value of showFront and I can see it changing with each click.

I have set conditional visibility for Container A to showFront == True.
This means, when showFront == True, Container A should overlap and hide Container B.
However, despite showFront changing between True and False, the visibility of Container A is never updated. Container A will always be shown and I cannot hide it.

Does anybody know what is going on and why I cannot update the visibility of my widget even though the value can be displayed in a Text-Widget?

Any help is greatly appreciated.
