Flutter list widget that allows to drag and drop items and define custom drag handle widget.
Add DragList component to your widget tree:
child: DragList<String>(
items: ['Tuna', 'Meat', 'Cheese', 'Potato', 'Eggs', 'Bread'],
itemExtent: 72.0,
builder: (context, item, handle) {
return Container(
height: 72.0,
child: Row(children: [
Spacer(),
Text(item),
Spacer(),
handle,
]),
);
},
),Optionally, provide custom handle builder:
child: DragList<String>(
// ...
handleBuilder: (context) {
return Padding(
padding: EdgeInsets.all(16.0),
child: Container(
color: Colors.green,
child: Text('Handle'),
),
);
},
),Add other optional parameter if needed:
child: DragList<String>(
// ...
animDuration: Duration(milliseconds: 500),
dragDelay: Duration(seconds: 1),
handleAlignment: -0.3,
scrollDirection: Axis.horizontal,
onItemReorder: (from, to) {
// handle item reorder on your own
},
),Use handleless constructor if you want list item to be dragged no matter where it's tapped on:
DragList<String>.handleless(
// ...
builder: (context, item) {
return Container(
height: 72.0,
child: Center(child: Text(item)),
);
},
),
