如何在flutter中更改checkBoxListTile内的复选框颜色？

Question

I am using the CheckBoxListTile like this,

CheckboxListTile(
            title: Text(
              ourAllnotes[i].note,
              style: TextStyle(color: Colors.white),
            ),
            value: false,
            onChanged: (bool value) {},
            activeColor: Colors.orange,
            checkColor: Colors.white,
            controlAffinity: ListTileControlAffinity.leading,
          )

I could change the color of the checkbox after it is checked, but I cannot change its color before it is checked rather than its default value. How to do that?

try wrap CheckBoxListTile with Theme widget and choose color at unselectedWidgetColor properties.

  Theme(
    data: ThemeData(unselectedWidgetColor: Colors.white),
    child: CheckboxListTile(
      checkColor: Colors.white,

      title: Text(
        "show password",
        style: TextStyle(
            fontSize: 12, color: Colors.white, letterSpacing: 2),
      ),
      value: checkboxflag,
      onChanged: (newValue) {
        setState(() {
          if (newValue) {
            checkboxflag = newValue;
            _obscureText = false;
          } else {
            checkboxflag = newValue;
            _obscureText = true;
          }
        });
      },
      controlAffinity:
          ListTileControlAffinity.leading, //  <-- leading Checkbox
    ),
  )
