Chip

Los chips son elementos compactos que representan un atributo, texto, entidad o acción.

Sus antepasados deben incluir Material, MediaQuery, Direccionalidad y MaterialLocalizations. Normalmente, todos estos widgets son proporcionados por MaterialApp y Scaffold. Los argumentos label y clipBehavior no deben ser nulos.
