nested_reorderable_list
A Flutter package that provides a widget to create a nested reorderable list.
Getting Started
This package provides a stateless widget, NestedReorderableList, which allows you to create a list with drag-and-drop item reordering functionality. This widget supports nested lists, meaning that list items can have their own children, which can also be reordered.
Usage
First, you’ll need to add nested_reorderable_list to your pubspec.yaml:
dependencies:
flutter:
sdk: flutter
nested_reorderable_list: ^0.0.1
Then, import the package in your Dart file:
import 'package:nested_reorderable_list/nested_reorderable_list.dart';
Here’s a basic example of how to use the NestedReorderableList widget:
In the example above, items is a list of DragAndDropItem instances, each of which contains a key for identification, the content of the item, and a list of child DragAndDropItem instances (if any). The itemBuilder is a function that takes a BuildContext and a DragAndDropItem and returns a Widget that represents the item. The onReorder function is called when a drag-and-drop operation finishes; it receives a SourceLocation and a DestinationLocation, which represent the initial and final locations of the dragged item, respectively.
