Hide flat rate shipping when the amount to have free shipping is reached.

Hey laboiteapixels12,
Thank you for your patience, try adding this code to the end of your child theme functions.php file in Appearance ▸ Editor:

function check_for_free_shipping() { ?>
    <script>
(function($){
	function check_shipping() {
	setTimeout(function () {
  $('#shipping_method').each(function() {
  $(this).find('li input.shipping_method').each(function(){
  	var shipping = $(this).attr('id');
    $(this).closest('li').addClass(shipping);
  });
  });
   $('#shipping_method .shipping_method_0_free_shipping1 + .shipping_method_0_flat_rate2').css({ 'display': 'none'});
	}, 1000);
	}
	check_shipping();
  $('#top.woocommerce-cart button[name="update_cart"]').click(function(){
  	setTimeout(function () {
   location.reload(true);
  	}, 1000);
  });
})(jQuery);
</script>
    <?php
}
add_action('wp_footer', 'check_for_free_shipping');

This gets each input ID and adds it as parent class (li) and hides the sibling li with css if the free shipping option is available and checks for update cart button click should user change quantity.
Please note that I had to add a 1s delay because woocommerce is slow to add the free shipping element, there is nothing I can do about that.
