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: ^0.0.6
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),
),
);
}
