transformer_page_view

PageTransformer 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

Getting Started

• Installation
• Basic Usage
• Build-in Parallax
• Custom animation

Installation

Add

transformer_page_view:

to your pubspec.yaml ,and run

flutter packages get 

in your project's root directory.

Basic Usage

Parameter	Default	Description
scrollDirection	Axis.horizontal	If Axis.horizontal, the scroll view's children are arranged horizontally in a row instead of vertically in a column.
loop	false	Set to true to enable continuous loop mode.
index	none	Index number of initial slide. if not set , it is controlled by the widget itself,otherwise, it is controlled by another widget, which is returned by itemBuilder
onPageChanged	void onPageChanged(int index)	Called with the new index when the user swiped
duration	new Duration(milliseconds:300)	The milliseconds of every transaction animation costs
transformer	none	The most important property of this widget, it returns a transformed widget that based on the widget parameter. If the value is null, a itemBuilder must be specified
itemCount	none	Number of the total items
itemBuilder	none	A function that returns a widget based on index,if it's null,a transformer must be specified

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.
