How to change the theme directory uri for localhost?

Question

In wp-config.php I have the following code to change the website path based on the environment of the website.

if ( theme_get_environment() === 'local' ) {
    define( 'WP_HOME', 'http://website.local' );
    define( 'WP_SITEURL', 'http://website.local' );
}

The database wp_home and wp_siteurl are pointing to the live website. But that is fine because that way I don't need an else statement to also define paths for the website.nl domain.

Now the problem is that when I use get_theme_file_uri() it returns this path: http://website.nl/wp-content/themes/theme2018. That should be a .local path! So how to fix this?

I already tried to use this approach in wp-config.php, but it didn't work:

if ( theme_get_environment() === 'local' ) {
    define( 'WP_HOME', 'http://website.local' );
    define( 'WP_SITEURL', 'http://website.local' );

    // fix theme directory uri for local website
    register_theme_directory('http://' . $_SERVER['HTTP_HOST'] . '/wp- 
    content/themes/theme2018');
}

So how can I fix the result of get_theme_file_uri() to be a local path. Without changing the database values? Defining WP_HOME and WPSITEURL should be enough, right?

Just found out a solution: The WP_HOME and WP_SITEURL DEFINE statements need to be above the wp-settings.php include rule inside of wp-config.php.
