i wanna change the icon in the checkbox.item in the react native .....i've used formik, yup for this form validation

I want to change the icon view because it's producing unsatisfactory results for form validation. I am new to React Native and I'm having trouble fixing the checkbox. React Native Elements blocked the checkbox and I need the link for the React Native Community checkbox where I can find examples of class-based components. I've tried implementing the suggested styling, but I'm still having a lot of confusion. Can you please assist me?
