shouldAlwaysShow property

bool shouldAlwaysShow
final

Enables or disables the crosshair.

By default, the crosshair will be hidden on touch. To avoid this, set this property to true.

Defaults to false

Widget build(BuildContext context) {
   return Container(
       child: SfCartesianChart(
          crosshairBehavior: CrosshairBehavior(enable: true, shouldAlwaysShow: true),
       ));
}
