Getting Started

Installing

In your Flutter project, add the package to your dependencies

flutter pub add expandable_sliver_list

or

dependencies:
  ...
  expandable_sliver_list: ^4.1.0
  ...

Usage Example

A complete example on how to use this widget can be found in the example directory. But the basics are:

Import the package

import 'package:expandable_sliver_list/expandable_sliver_list.dart';

Create a controller and a list of items to display

ExpandableSliverListController controller = ExpandableSliverListController();

List<int> items = [1, 2, 3, 4, 5];

Create the widget

ExpandableSliverList<int>(
  initialItems: items,
  controller: controller,
  builder: (context, item, index) {
    return ListTile(
      title: Text(item.toString()),
    );
  },
)

Now you can use the controller to expand or collapse the list

controller.collapse();
controller.expand();

Or to add items to the list

controller.insertItem(54, 2);
controller.removeItem(4);
