“_drawAreaBoundsOutdated == false': is not true”使用 charts_flutter 包更新 TimeSeriesChart 的列表数据时出错

Question

我收到以下错误：

“_drawAreaBoundsOutdated == false': 不正确”

每当我使用 charts_flutter 包通过 Steam 更新 TimeSeriesChart 的列表数据时。 https://pub.dev/packages/charts_flutter 如果我执行任何操作以在页面上再次设置状态，图表将正确重建。请帮忙，这里描述的解决方法：https://github.com/flutter/flutter/issues/31778 仍然会导致异常。

Answer 1

将图表存储在有状态小部件中这样的变量中，

Widget _timeSeriesChart;

然后像这样获取数据 setState，

 setState(() {
  _timeSeriesChart = charts.TimeSeriesChart(
    incomeExpensesList, // This is the data you forge after completing API call.
    animate: true,
    defaultRenderer: charts.LineRendererConfig(),
    customSeriesRenderers: [
      charts.PointRendererConfig(
        customRendererId: 'customPoint',
      )
    ],
    dateTimeFactory: const charts.LocalDateTimeFactory(),
  );
});
