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.

Comienza revisando la implementación actual de PagerView y LazyPagerView, así como los issues relacionados #436 y #386. Determina si la arquitectura existente puede medir las alturas variables de los elementos secundarios y define la finalización de modo que la altura de PagerView se ajuste al elemento secundario mostrado actualmente en las plataformas compatibles.
