flutter 按钮选择状态颜色更改

开发需求：

 

代码如下： 

bool check = false;

getCheckBoxBorderColor() {
    if (check) {
      return const Color(0xFF7F69D9);
    } else {
      return const Color(0xFFD1D1D1);
    }
}


RoundCheckBox(
     size: 16, //checkBox大小
     checkedWidget: const Icon(
         Icons.check,
         color: Colors.white,
         size: 8,
     ),

     checkedColor: const Color(0xFF7F69D9),
     uncheckedColor: const Color(0xFFF6F8FA),
     border: Border.all(color: getCheckBoxBorderColor(), width: 1),

     isChecked: check,
     onTap: (selected) {
         
       if(check){
                          
         check = false;

       } else {

         check = true;
         
       }
          
    }

),
