Chip class

A material design chip.

Chips are compact elements that represent an attribute, text, entity, or action.

Supplying a non-null onDeleted callback will cause the chip to include a button for deleting the chip.

Requires one of its ancestors to be a Material widget. The label, deleteIcon, and border arguments must not be null.

Sample code

new Chip(
  avatar: new CircleAvatar(
    backgroundColor: Colors.grey.shade800,
    child: new Text('AB'),
  ),
  label: new Text('Aaron Burr'),
)
