Charts [2148⭐] - By Google Team.

This is an automatically generated pull request.

Finally syncing out after someone internal generously went through and marked everything with null safety.

I have intention on looking for a specific point in a line chart of charts_flutter and then display the the marker to highlight the point after a points or bar is hit.

My question is, Is it possible to create a widget or add some label to the line chart and bar chart?

below is based on the my line chart example, on android apps

Hi,

Please check out the most recent flutter version. body1 is deprecated and now removed. Please change to bodyText1 and make a new Version. The package is completly broken at the moment.

charts_flutter-0.11.0/lib/src/behaviors/legend/legend_entry_layout.dart(134,45): error GD65BB2B6: The getter 'body1' isn't defined for the class 'TextTheme'.

The published version pulled through pubspec.yaml does not contain the same code as in master? Is there something I need to do on my end, or is it just waiting for a version bump. Specifically I was trying to get the "Gauge" chart.

Thanks

I get the following error when I compile my app:

Hi I wan to show y-axis values as label on top-center of barcharts, but the lables (values provided by the labelAccessorFn) are shown in top-left side. why?

//barchart:
charts.BarChart(
        data(statistics),
        animate: true,
        barRendererDecorator: charts.BarLabelDecorator(
           insideLabelStyleSpec: charts.TextStyleSpec(color: charts.ColorUtil.fromDartColor(Colors.white)),
           outsideLabelStyleSpec: charts.TextStyleSpec(color: charts.ColorUtil.fromDartColor(Colors.white)),
        ),

          renderSpec: charts.SmallTickRendererSpec(
            labelRotation: 45,

              fontSize: 18,

            ),
          ),
        ),
      ),
