Issue
Hello Folks I am playing with Buttons to customize the buttons but I didn’t find a way to approach the expected design. basically, I wanted to customize the 1) Multiple checkBoxes with Grey color Background and Black color Check Mark 2) RangeSlider Inactive bar with Grey color 3) Radio Button with black Color and I Want to unselect all, I understand that in Radio Button user cant Unselect all the buttons but I Want to unselect all with or without Radio Buttons(any different way is also fine) 4) same as 3rd point but Square Box with Grey color Background and Black color Check Mark. I attached a screenshot of my code and Expected design and also pasted my code. Please guys Help me to approach Expected Design, Please feel free to do comments for any clarity. Thanks in Advance.

Solution
To change color of checkbox you can use
Checkbox(
value: isCheck,
checkColor: Colors.black, // change color here
activeColor: Colors.grey,
onChanged: (bool value) {
setState(() {
isCheck = value;
});
}),
To change color of radio button try
Theme(
data: ThemeData(
//Change color here
unselectedWidgetColor: Colors.grey,
),
child: Row(
children: <Widget>[
Radio(),
Radio()
],
),
);
