Getting started

In the pubspec.yaml of your flutter project, add the following dependency:

dependencies:
  ...
  flutter_parallax: "^0.1.2"

In your library add the following import:

import 'package:flutter_parallax/flutter_parallax.dart';

For help getting started with Flutter, view the online documentation.

Example

new Parallax.inside(
    child: new Image.network('https://flutter.io/images/homepage/header-illustration.png'),
    mainAxisExtent: 150.0,
);

You can find more examples in the Example project.

Constructors

• The Parallax.inside, that computes the parallax offset from its position in its first Scrollable parent. Useful for list or grid items.
• The Parallax.outside, that computes the parallax offset from the percentage of the scrollable's container extent. Useful for a list or grid background.
• The Parallax.custom takes a ParallaxDelegate, which provides the ability to customize additional aspects of the child model. For example, a ParallaxDelegate can control the algorithm used to computes the parallax offset of the child within its parent.
