Since my data have the date and time value, I want to set the bottom title with the date and interval by time to display the value(bloodSugar).

class BloodSugarModel (
  final String? bsID;
  final double bloodSugar;
  final String? remark;
  final String date;
  final String time;
)

Wanted the chart

给你提供一个思路，再多设置一个double的时间属性，把日期转换成时间戳，然后x轴的对你的数据时间戳进行绘制Line，并对X轴的数据标签进行格式转化输出，即把时间戳转换成"MM/dd/yyyy"的文字标签内容。
