Pull request overview
Removes deprecated/composed Chip utility classes from Material UI, updating the component’s class generation, tests, and documentation to rely on atomic classes and variant-based styling consistent with the v9 upgrade path.
Changes:
- Removed deprecated
ChipClasseskeys and stopped generating the corresponding utility classes. - Updated
Chipclass composition and style resolution to no longer reference deprecated class names. - Updated unit tests and API/migration docs to reflect the removed classes and recommended replacements.
