代码演示

横向实线分隔符

 HcDivider(
    decoration: Axis.horizontal,
    color: Colors.blue,
    thickness: 1,
    ),

横向实线增加宽度分隔符

 HcDivider(
    //横向中spacing指宽度
    spacing:10
    decoration: Axis.horizontal,
    color: Colors.blue,
    thickness: 1,
    ),

横向增加距离起始位置的分隔符

       HcDivider(
            decoration: Axis.horizontal,
            color: Colors.blue,
            thickness: 1,
            indent: 8,
            endIndent: 8,
          ),

纵向实线分隔符

      HcDivider(
          decoration: Axis.vertical,
          color: Colors.blue,
          thickness: 1,
        )
