How to fill color inside of checkbox in flutter?

Here is what I am using for checkbox in flutter. But I can set only border color for unchecked state, not method found for fill color inside of the checkbox. Please help me with this.

Theme(
    data: ThemeData(unselectedWidgetColor: Colors.white),
    child: Checkbox(
        checkColor: Colors.blue,
        activeColor: Colors.white,
        value: rememberMe,
        onChanged: (value) {
            setState(() {
                rememberMe = value;
            });
        },
    ),
)
