Getting an error. Need to add favicon in my child theme functions.php. What's wrong?

When I put this code in my functions.php

add_action('wp_head', 'my_favicon');
function my_favicon() {
    echo "<link rel='shortcut icon' href=' " . get_stylesheet_directory_uri() .
         '/images/favicon.ico'"'>";
}

I get

[Message from webpage]: There has been a critical error on this website. Learn more about debugging in WordPress.

What's wrong with my code?

@Michael The error was when a reload the webpage. [Message from webpage]: There has been a critical error on this website. Learn more about debugging in WordPress. I put this line of code in my functions.php. code **add_action('wp_head', 'my_favicon'); function my_favicon() { // echo "<link rel='shortcut icon' href=' " . get_stylesheet_directory_uri() . '/images/favicon.ico'"'>"; } ** code – Jerry Fleurival Commented Feb 15, 2021 at 0:30
1 You've got a syntax error: that '/images/favicon.ico'"' should be "'/images/favicon.ico'. And the href should have no whitespace at the beginning, so use href='". – Sally CJ Commented Feb 15, 2021 at 0:39
1 Sorry @JerryFleurival, I meant, "/images. But why don't you just use the Customizer → Site Identity → Site Icon to set the site icon (or favicon)? – Sally CJ Commented Feb 15, 2021 at 1:42
1 @SallyCJ Awesome that fixed it. Thank you so much. Muneeb solved it too. I'm aware of using Customizer. I'm just a person who likes to know everything under the hood.
