ElasticListView

Description

ElasticListView is a drop-in replacement for Flutter’s ListView, enhancing the user experience by dynamically calculating each item’s padding based on the scroll speed, creating an elastic effect. It supports the builder and separated constructors as well as the standard ListView constructor. To migrate to ElasticListView, simply add the Elastic prefix to any existing ListView widget.

Features

• Features Elastic Effect: ElasticListView provides an elastic effect to each item by dynamically calculating the padding based on the scroll speed, which is different from the traditional overscroll effect. This makes the list appear as if it’s made of rubber.
• Drag to Scroll: Adds the drag to scroll behavior by default, providing a smooth scrolling experience. This can be disabled by setting the enableDragScrolling property to false.
• Optimized Performance: Leverages the performance optimizations of the standard ListView, ensuring excellent performance.

Extended Functionality with Full Compatibility

ElasticListView maintains the exact same properties as the standard ListView, ensuring full compatibility and making it a seamless replacement. In addition, it introduces new properties to control the elastic effect, offering enhanced functionality and customization options beyond the standard ListView.

New Properties

Here are the new properties introduced by ElasticListView:

• curve: The curve to apply when animating the elastic effect. Defaults to Curves.easeOut.
• animationDuration: The duration of the elastic effect. Defaults to Duration(milliseconds: 200).
• enableDragScrolling: Whether to enable drag scrolling. Defaults to true.
• elasticityFactor: The factor by which the scroll view’s padding changes dynamically based on the scroll speed. Defaults to 4.

Each of these properties allows you to customize the behavior of the elastic effect in ElasticListView.

Usage

To use ElasticListView, simply replace your existing ListView with ElasticListView. All the properties are the same, ensuring full compatibility.

For ListView:

ElasticListView(
  children: <Widget>[
    ListTile(
      leading: Icon(Icons.map),
      title: Text('Map'),
    ),
    ListTile(
      leading: Icon(Icons.photo_album),
      title: Text('Album'),
    ),
    ListTile(
      leading: Icon(Icons.phone),
      title: Text('Phone'),
    ),
  ],
)

For ListView.builder:

ElasticListView.builder(
  itemCount: 10,
  itemBuilder: (context, index) {
    return ListTile(
      title: Text('Item $index'),
    );
  },
)

And for ListView.separated:

ElasticListView.separated(
  itemCount: 10,
  separatorBuilder: (BuildContext context, int index) => Divider(),
  itemBuilder: (BuildContext context, int index) {
    return ListTile(
      title: Text('Item $index'),
    );
  },
)
