With dynamic input, pager view assumes the new added element is at the end and not at the beginning.

[sirusbaladi]

if we pass an array and we update the array adding a new element at the beginning of the array, native pager assumes that the element is added at the end. There should be an option to edit this.

This causes various bugs:

• setPage doesn't work. Calling setPage(0) actually scrolls to the second element given that a new one was added but it's not take into account.
• the scroll dots go out of sync.

The code is simply the standard example of PagerView but passing an array with an extra element at the beginning dynamically.
