[Solved] Old WordPress code got "creation of dynamic property is deprecated" warning – WordPress

The Solutions:

Solution 1: Declare Dynamic Properties Before Use

Starting from PHP 8.2, dynamic properties in objects are deprecated. To resolve the "Creation of dynamic property is deprecated" warning, you can declare the $MyStyle property before using it in the JSXStyle class:

class JSXStyle {

  // Declare the $MyStyle property before use.
  protected string $MyStyle;

  public function __construct( $name ) {
    $this->MyStyle = $name;
    add_action( 'wp_enqueue_scripts', array( $this, 'register_custom_style' ) );
  }

  public function register_custom_style() {
    wp_enqueue_style( $this->MyStyle, get_stylesheet_directory_uri() . "/css/{$this->MyStyle}.css", array(), '4.0.0' );
  }
}
