分时图运行是正常的，但K线部分报错：

[log] 更新日K数据，数据长度：1 [log] KChartDataSource notifyListeners rightmost ======== Exception caught by rendering library ===================================================== The following assertion was thrown during paint(): Rect argument contained a NaN value.

The relevant error-causing widget was: KChartWidget KChartWidget:file:///D:/AppGallery/GitHub/flutter_kline/example_network/lib/example_network/example_day_network_widget.dart:78:12 When the exception was thrown, this was the stack:

很抱歉，很长一段时间估计都不会再维护网络示例，实在是不够精力，后续有时间精力也是慢慢迭代K线图的画线功能。
