As per the current implementation of BarTooltipItem, the function to customize the tooltip is as below

BarTooltipItem touchTooltipData(BarChartGroupData group, int groupIndex, BarChartRodData rod, int rodIndex)

The callback is missing the index for stack position, because of this the tooltip cannot be customized as per stack position.

Added touchedStackItem and touchedStackItemIndex properties in the BarTouchedSpot ,
check it out in the 0.11.0 version.
Thanks for your suggestion!

But this still does not help with tooltop, I am specifically talking about callback defined to get tooltip text...
BarTooltipItem touchTooltipData(BarChartGroupData group, int groupIndex, BarChartRodData rod, int rodIndex),

Can you pass BarTouchedSpot to touchTooltipData (property of BarTouchData)? It would be a breaking change, but would be better than having 6 parameters to a function.
