btrautmann commented 1 month ago

Bug description

When dragging finger across chart while using trackballBehavior the following is thrown:

The following RangeError was thrown while dispatching a pointer event:
RangeError (index): Invalid value: Valid value range is empty: 0

See below for full stacktrace.

Steps to reproduce

Create Cartesian chart that uses trackballBehavior. Note that the issue seems to be specific to using TrackballDisplayMode.groupAllPoints.

trackballBehavior: TrackballBehavior(
  enable: true,
  tooltipDisplayMode: TrackballDisplayMode.groupAllPoints,
  builder: (context, details) {
    return Text(details.toString());
  },
  activationMode: ActivationMode.singleTap,
),

Tap and hold and drag finger towards Y axis
Once Y axis is hit (or right around it) the error is thrown

Hi @btrautmann,

We can replicate the reported issue regarding the trackball display mode as groupAllPoints with empty points. This issue is scheduled to be fixed in our upcoming weekly release which is scheduled on April 30, 2024. We will update you here once the release is rolled out and we appreciate your patience until then.

Regards,

Preethika Selvam.
