RawChip class Null safety

A raw material design chip.

This serves as the basis for all of the chip widget types to aggregate. It is typically not created directly, one of the other chip types that are appropriate for the use case are used instead:

  • Chip a simple chip that can only display information and be deleted.
  • InputChip represents a complex piece of information, such as an entity (person, place, or thing) or conversational text, in a compact form.
  • ChoiceChip allows a single selection from a set of options.
  • FilterChip a chip that uses tags or descriptive words as a way to filter content.
  • ActionChips display a set of actions related to primary content.

Raw chips are typically only used if you want to create your own custom chip type.

Raw chips can be selected by setting onSelected, deleted by setting onDeleted, and pushed 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.
