WordPress wp_enqueue_style and wp_enqueue_script not working

Your action is wp_enqueue_script and not wp_enqueue_scripts. This should fix it. Lemme know how it goes! 🙂

<?php
//Adding the css and js files
function gt_setup(){
    wp_enqueue_style('google-fonts','https://fonts.googleapis.com/css?family=Roboto|Roboto+Condensed|Roboto+Slab');
    wp_enqueue_style('font-awesome','https://use.fontawesome.com/releases/v5.1.0/css/all.css');
    wp_enqueue_style('style',get_stylesheet_uri());
    // wp_enqueue_script($handle,$src,$deps,$ver,$in_footer);
    wp_enqueue_script('main',get_theme_file_uri('/js/main.js'),NULL,'1.0',true);
}
add_action('wp_enqueue_scripts','gt_setup');
?>
