How to set PageView scrolling Threshold values?

Hi All
I am using PageView to accommodate my 35 buttons which take the user to different 35 screens.
But most of the time when i touch the on a button inside the PageView, The PageView try to scroll as finger moves on micro level when we touch the screen in real life scenario. Is there any way we can set a threshold value to restrict the scroll of pageView.
Or what is the appropriate way to implement PageView?

Anyone?
no solution or work around?
