drag_and_drop_lists 0.0.2

A flutter package to allow drag-and-drop reordering of two-level lists.

drag_and_drop_lists

Two-level drag and drop reorderable lists.

Features

• Reorder elements within a single list
• Reorder lists
• Drag and drop new elements from outside of the lists
• Vertical or horizontal layout
• Expandable lists
• Can be used in slivers
• Easy to extend with custom layouts

Usage

To use this plugin, add drag_and_drop_lists as a dependency in your pubspec.yaml file. For example:

dependencies:
  drag_and_drop_lists: ^1.0.0

Now in your Dart code, you can use: import 'package:drag_and_drop_lists/drag_and_drop_lists.dart';

To add the lists, add a DragAndDropLists widget. Set its children to a list of DragAndDropList. Likewise, set the children of DragAndDropList to a list of DragAndDropItem. For example:

...

  DragAndDropLists(
    children: List.generate(_lists.length, (index) => _buildList(index)),
    onItemReorder: _onItemReorder,
    onListReorder: _onListReorder,
  ),

...

_buildList(int outerIndex) {
  var innerList = _lists[outerIndex];
  return DragAndDropList(
    title: Text('List ${innerList.name}'),
    children: List.generate(innerList.children.length, (index) => _buildItem(innerList.children[index])),
  );
}

_buildItem(String item) {
  return DragAndDropItem(
    child: ListTile(
      title: Text(item),
    ),
  );
}
