Yet another pageTransformer for flutter with null-safety support

another_transformer_page_view #

PageTransformer for flutter. Fork from transformer_page_view

Very simple to use #

import 'package:another_transformer_page_view/another_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.

Inspired by page-transformer, and we have an easier way to create this.
