Trackball still shows for a few seconds，after fingers move away from chart about flutter-examples HOT 1 CLOSED

Hi @Cyycl ,

Thanks for your interest in our Syncfusion Flutter chart widget. As of now, the trackball disappears when the finger is moved away, and this is our current behavior. Your requirement for taking screenshots can be accomplished using shouldAlwaysShow of property. When shouldAlwaysShow property is set to true, the trackball will not get hidden. Find the code snippet below to achieve this.

SfCartesianChart(
trackballBehavior: TrackballBehavior(
enable: true,
shouldAlwaysShow: true
),
//...
)

And you can hide the trackball using the hide method. To know more about public methods, find the user guide.

We have also logged feature request in our feedback portal to provide, delay for trackball to disappear using an API. You can track the status of the feature using our feedback portal from below.

Hope this helps.

Thanks,
