Line chart keep FlLine visible

[zychns]

Hi guys,
Can the FlLine be kept visible on the Line chart all the time after the first interaction?
Currently, the line disappears after each touch.
In addition is there a way to show x,y cords after touch through callback?

found a solution by setting up showingIndicators (following line chart #5), setting handleBuiltInTouches: false, and adding the following to touchCallback:
touchCallback: (touchEvent, response) {
if (response == null || response.lineBarSpots == null) {
return;
}
if (touchEvent is FlTapDownEvent ||
touchEvent is FlPanUpdateEvent) {
final spotIndex = response.lineBarSpots!.first.spotIndex;
setState(() {
showingTooltipOnSpots.clear();
showingTooltipOnSpots.add(spotIndex);
});
}
},
