How to close infinity re-render?

[emrecoban]

My Formik form always re-rendering. I have no idea why. How to close it?

<Formik
    validationSchema={appointmentValidation}
    initialValues={{
        // total_step
        step: 1,
        totalStep: 3,

        // step -> 1
        appointment_date: '',

        // step -> 2
        event_type: '',

        // step -> 3
        appointment_time: '',
    }}
    onSubmit={async (values, actions) => {
        // do something.
    }}
>
    {({
        isSubmitting,
        status,
        values,
        setFieldValue,
        isValid,
        dirty
    }) => {

        // This part always re-render? if call a function
        // You can see in console
        if(values.step===2){
                callFunction()
                console.log("rendering...")
        }
        return (
            <Form>
                {/* Your form fields and components go here */}
            </Form>
        );
    }}
</Formik>
