onLongPress property Null safety

GestureLongPressCallback? onLongPress
final

Called if the row is long-pressed.

If a DataCell in the row has its DataCell.onTap, DataCell.onDoubleTap, DataCell.onLongPress, DataCell.onTapCancel or DataCell.onTapDown callback defined, that callback behavior overrides the gesture behavior of the row for that particular cell.

Implementation

final GestureLongPressCallback? onLongPress;
