persist current page if we add item at the start of array

## Describe the feature

```

{posts.items.map(renderItem)}

```
for example, I have an array like this `posts=[4,5,6,7]` which I render in `PagerView` and go to the index 2 means `6`
then I add some items at the start of the array
```
[1,2,3].concat(posts)
```
when I set state I lost my current page which is logical `6`. I think there should be a prop for persisting current page if I add items at the start of an array

## Motivation
like TIKTOK app, when we swipe up and up then pagination api call and TikTok add more video at the start of an array
