This plugin for Flutter makes it easier for you to create a list with a parallax effect, providing several animations types and customizations options.

Getting Started

Add this to your package's pubspec.yaml file:

dependencies:
  pageview_parallax: 1.0.0

Usage

Simply import the package:

import 'package:pageview_parallax/pageview_parallax.dart';

To create a parallax effect, just use the FlutterParallax constructor, and pass your screens as a child of the screens parameter.

A minimal implementation would look like this:

  List<Widget> screens = <Widget>[
    Container(),
    Container(),
  ];

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: FlutterParallax(
        screens: screens,
        backgroundImage: NetworkImage(
          "https://www.richardtmoore.co.uk/wp-content/uploads/2016/10/btx-background-placeholder-03-1024x683.jpg",
        ),
      ),
    );
  }

If you'd like to add a child that move while the page scrolls, in one of your screens, just add a FlutterParallaxChild, and pass the child on the child property.

Using the example above:

List<Widget> screens = <Widget>[
    FlutterParallaxChild(
      child: Text("Hey, I can move!"),
    ),
    Container(),
  ];

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: FlutterParallax(
        screens: screens,
        backgroundImage: NetworkImage(
          "https://www.richardtmoore.co.uk/wp-content/uploads/2016/10/btx-background-placeholder-03-1024x683.jpg",
        ),
      ),
    );
  }

Notice the child that was added at the screens array of Widgets.
