Description

AxisTitles( sideTitles: SideTitles(showTitles: true, getTitlesWidget: (double value, TitleMeta meta) { return SideTitleWidget( axisSide: meta.axisSide, child: Text(value.toString()), ); }), )

Hello, in above code, the getTitlesWidget function transmit x's value. Can it transmit x's index in the future? I have a list consist of map. The map has value and title, I want give the value to x, and give the title to getTitlesWidget. If x's index can be transmitted to getTitlesWidget function, I can use it to achieve title from my list directly. Thank you very much!

Contributor guide

Research direction
Modify the getTitlesWidget callback to include the index of the data point. Investigate how the current AxisTitles component iterates over values and pass the index as an additional parameter.
