I would like the Height to be scaled according to the children

## Describe the feature

I saw that there are numerous issues saying that the height of the PagerView is not according to the height of the children. I wish it was. Is it possible to implement this in the current source code architecture? Is there any direction? I would like to do a PR with this, but first I wanted to know if it's possible.

I saw the workarounds and in my use case they are not enough.

## Motivation

I have several pages that have varying sizes. I use LazyPagerView from the new Pre-Release version, so I can't consider the highest height of the first pages.

Beginne mit der Überprüfung der aktuellen Implementierung von PagerView und LazyPagerView sowie der zugehörigen Issues #436 und #386. Ermittle, ob die bestehende Architektur die Höhen unterschiedlich großer untergeordneter Elemente messen kann, und definiere den Abschluss so, dass sich die Höhe von PagerView auf allen unterstützten Plattformen an das aktuell angezeigte untergeordnete Element anpasst.
