shouldAlwaysShow property

bool shouldAlwaysShow

Defaults to false.

void initState() {
  tooltipBehavior = TooltipBehavior(
    enable: true,
    shouldAlwaysShow: true
  );
  super.initState();
}

Widget build(BuildContext context) {
  return SfCartesianChart(
    tooltipBehavior: tooltipBehavior
  );
}
