headingRowAlignment property
final
Defines the horizontal layout of the label and sort indicator in the heading row.
If headingRowAlignment value is MainAxisAlignment.center and onSort is not null, then a SizedBox with a width of sort arrow icon size and sort arrow padding will be placed before the label to ensure the label is centered in the column.
If null, then defaults to MainAxisAlignment.start.
Implementation
final MainAxisAlignment? headingRowAlignment;
