transformer_page_view

Page Transformer for flutter.

Very simple to use

import 'package:transformer_page_view/transformer_page_view.dart';

...

new TransformerPageView(
loop: true,
transformer: new AccordionTransformer(),
itemBuilder: (BuildContext context, int index) {
  return new Container(
    color: list[index%list.length],
    child: new Center(
      child: new Text("$index",style: new TextStyle(fontSize: 80.0,color: Colors.white),),
    ),
  );
},
itemCount: 3)

Almost the same as PageView.builder, simplely specify a transformer to TransformerPageView,
which is a sub class of PageTransformer

Build-in Parallax

We provide 3 build-in parallaxes, which handle color、image and container

ParallaxColor

ParallaxColor handles the color transform, which controls the color transform from one to another.

ParallaxImage

ParallaxImage handles the image, which speed is slower than the PageView

ParallaxContainer

ParallaxContainer handles the text or other staff, which speed is faster than the PageView

3 build-in parallaxes are all used in subclass of PageTransform,group these parallaxes together, we can create very cool things.
