expandable_sliver_list

A Flutter widget which creates a Sliver List that you can then either expand or collapse, in order to show or hide the contents of the list.

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);
