• The value parameter is used to set the value of the Radio button. It should be an enum value that corresponds to the letter displayed in the button.
• The groupValue parameter is used to determine which Radio button in a group is selected. It should be a variable that holds the currently selected enum value.
• The mcqOptionAlphabetStyle parameter is used to set the style of the letter displayed in the Radio button.
• The circleRadius parameter is used to set the size of the Radio button.
• The mcqOptionAlphabet parameter is used to set the letter displayed in the Radio button.
• Use the onChanged parameter to update the selected enum value when the Radio button is selected.
