InputChip class Null safety

A Material Design input chip.

Input chips represent a complex piece of information, such as an entity (person, place, or thing) or conversational text, in a compact form.

Input chips can be made selectable by setting onSelected, deletable by setting onDeleted, and pressable like a button with onPressed. They have a label, and they can have a leading icon (see avatar) and a trailing icon (deleteIcon). Colors and padding can be customized.

Requires one of its ancestors to be a Material widget.

Input chips work together with other UI elements. They can appear:

InputChip(
  avatar: CircleAvatar(
    backgroundColor: Colors.grey.shade800,
    child: const Text('AB'),
  ),
  label: const Text('Aaron Burr'),
  onPressed: () {
    print('I am the one thing in life.');
  }
)
