Material Chip button semantics

You might not need to perform any migration. This change only affects you if you worked around the issue of Material Chips missing button semantics by wrapping the widget given to the label field of a Chip with a Semantics widget marked as button: true. In this case, the inner and outer button semantics conflict, resulting in the tappable area of the button shrinking down to the size of the label after this change is introduced. Fix this issue either by deleting that Semantics widget and replacing it with its child, or by removing the button: true property if other semantic properties still need to be applied to the label widget of the Chip.

The following snippets use [InputChip][] as an example, but the same process applies to [ActionChip][], [ChoiceChip][], and [FilterChip][] as well.

Case 1: Remove the Semantics widget.

Code before migration:

Widget myInputChip = InputChip(
  onPressed: () {},
  label: Semantics(
    button: true,
    child: Text('My Input Chip'),
  ),
);

Code after migration:

Widget myInputChip = InputChip(
  onPressed: () {},
  label: Text('My Input Chip'),
);

Case 2: Remove button:true from the Semantics widget.

Code before migration:

Widget myInputChip = InputChip(
  onPressed: () {},
  label: Semantics(
    button: true,
    hint: 'Example Hint',
    child: Text('My Input Chip'),
  ),
);

Code after migration:

Widget myInputChip = InputChip(
  onPressed: () {},
  label: Semantics(
    hint: 'Example Hint',
    child: Text('My Input Chip'),
  ),
);
