Flutter PageView how to make faster animations on swipe

Question

I have a simple PageView:

PageView(
  controller: _pageController,
  physics: PlatformScrollPhysics.getPlatformScrollPhysics(),
  children: [
    Text("I am          


        

Answer 1

cs guy's answer is right on track. Also credit to pskink.The PageView widget's transition speed isn't based on an animation curve even though the programmatic approach is.

PageView actually uses a Spring Simulation to handle the page transitions when used with swiping, so the "physics" property has to be overridden to change the "animation speed".

Here is a simple way to increase the "animation speed" by using custom Scroll Physics class.

import 'package:flutter/cupertino.dart';
import 'package:flutter/physics.dart';

class CustomPageViewScrollPhysics extends ScrollPhysics {
  const CustomPageViewScrollPhysics({ScrollPhysics parent})
      : super(parent: parent);

  @override
  CustomPageViewScrollPhysics applyTo(ScrollPhysics ancestor) {
    return CustomPageViewScrollPhysics(parent: buildParent(ancestor));
  }

  @override
  SpringDescription get spring => const SpringDescription(
        mass: 80,
        stiffness: 100,
        damping: 1,
      );
}

It can be used in the PageView constructor like this:

PageView(... physics: const CustomPageViewScrollPhysics(),)

And feel free to adjust any of the spring parameters!
