如何在flutter中通过单击线形图中的点来显示工具提示中每个点的数据？

dependencies:
  flutter:
    sdk: flutter
  charts_flutter: ^0.10.0

import 'package:charts_flutter/flutter.dart' as charts;

List<charts.Series<YourDataClass, num>> seriesList = [
  charts.Series(
    id: 'Data',
    data: [
      YourDataClass(x: 0, y: 5),
      YourDataClass(x: 1, y: 10),
      YourDataClass(x: 2, y: 15),
      // 添加更多的数据点
    ],
    domainFn: (YourDataClass data, _) => data.x,
    measureFn: (YourDataClass data, _) => data.y,
  ),
];

charts.LineChart(
  seriesList,
  animate: true,
  behaviors: [
    charts.LinePointHighlighter(
      symbolRenderer: charts.CircleSymbolRenderer(),
      showHorizontalFollowLine:
          charts.LinePointHighlighterFollowLineType.none,
      showVerticalFollowLine:
          charts.LinePointHighlighterFollowLineType.nearest,
    ),
  ],
  selectionModels: [
    charts.SelectionModelConfig(
      type: charts.SelectionModelType.info,
      changedListener: (charts.SelectionModel model) {
        if (model.hasDatumSelection) {
          // 获取选中的数据点
          final selectedDatum = model.selectedDatum.first;
          // 获取x和y值
          final x = selectedDatum.datum.x;
          final y = selectedDatum.datum.y;
          // 在这里处理选中数据点的逻辑
        }
      },
    ),
  ],
)
