fields property
The fields that should be updated.
At least one field must be specified. The root style
is implied and
should not be specified. A single "*"
can be used as short-hand for
listing every field. For example, to update the text style to bold, set
fields
to "bold"
. To reset a property to its default value, include
its field name in the field mask but leave the field itself unset.
Implementation
core.String? fields;
