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.

Inizia esaminando l’implementazione attuale di PagerView e LazyPagerView e le issue correlate #436 e #386. Determina se l’architettura esistente è in grado di misurare altezze variabili degli elementi figli, quindi definisci il completamento in modo che l’altezza di PagerView si adatti all’elemento figlio attualmente visualizzato sulle piattaforme supportate.
