[con-cis]

Describe the bug
BarChart Tooltip animation lags behind on fast value changes. The data is provided with a simple provider

touchTooltipData: BarTouchTooltipData(
                tooltipBgColor: Colors.transparent,
                tooltipBottomMargin: -10,
                getTooltipItem: (
                  BarChartGroupData group,
                  int groupIndex,
                  BarChartRodData rod,
                  int rodIndex,
                ) {
                  String display;
                  if (groupIndex == 0 && riskLabel != null) {
                    display = riskLabel;
                  } else {
                    display = StringUtils.format(rod.y) + '%';
                  }
                  return BarTooltipItem(
                    display,
                    const TextStyle(
                      color: Colors.black,
                    ),
                  );
                },
 ),

Hmm, I think we should disable the tooltip's number animation.
What do you think?

You should do this inside the library.
