title: PageView : How to change scrolling speed and smoothness
body: <p>I am trying to change the speed of scrolling and make it smooth on this PageView item : </p>
  
  <pre><code>PageView.builder(
                  // store this controller in a State to save the carousel scroll position
                  controller: controller,
                  itemBuilder: (BuildContext context, int itemIndex) {
                    return _buildCarouselItem(context, carouselIndex, itemIndex);
                  },
                  physics: PageScrollPhysics(),
                  itemCount: Itmes.length,
                  onPageChanged: (int) {
                    OnNext(int);
                  },
                )
  </code></pre>
  
  <p>It's not that different but, I must say that I can do the speed change when dynamically switching between pages but as a default option.</p>
  
  <p><strong>EXPLANATION :</strong> When using a page view, you can scroll the pages, which each scroll an animation is working. that animation take a lof of time and  is much more smoother than I want it to be. My question is Can I speed up that animation and make it a bit sharper ?   </p>
