PHP 8.2 Deprecation Warning: Dynamic property creation in MarkdownField class

[Martinhessmann]

Bug Report

Environment

• PHP Version: 8.2+
• WordPress Version: [your version]
• Plugin Version: [current version]

Issue

Getting a deprecation warning in PHP 8.2:

Deprecated: Creation of dynamic property Fresh\ACFMarkdownField\MarkdownField::$settings is
deprecated in
/var/www/html/wp-content/plugins/wp-acf-markdown-field-main/src/MarkdownField.php on line
45

Root Cause

The $settings property is being assigned on line 45 without being declared in the class
definition.

Fix

Add property declaration to the MarkdownField class:

class MarkdownField extends acf_field
{
    /** @var \Fresh\ACFMarkdownField\Helpers $helpers */
    protected $helpers;

    /** @var array $settings Plugin settings */
    protected $settings;  // Add this line

    // ... rest of class
}

This resolves the PHP 8.2 deprecation warning while maintaining backward compatibility.
