Tutorial Configuration Version

The entirety of poggit plugins that checks for a config-version uses a constant integer from the plugin's code.
That is a bad practice and could be improved since most people forget to change their config-version in the plugin's code.
I came up with this simple solution when I fixed a bug in another plugin that forgot to change the config version.
This code snippet gets the config version from the resources folder of the plugin, and then it checks it with the plugin_data config version.

Spoon feed below:

PHP:

private function checkConfig() :void{
   $configVersionKey = "config-version";
   $pluginConfigResource = $this->getResource("config.yml");
   $pluginConfig = yaml_parse(stream_get_contents($pluginConfigResource));
   fclose($pluginConfigResource);
   $config = $this->getConfig();

    if($pluginConfig == false) {
        $this->getLogger()->critical("Something went wrong with the stream.");
        $this->getServer()->getPluginManager()->disablePlugin($this);
        return;
    }
   
    if($config->get($configVersionKey) === $pluginConfig[$configVersionKey]) return;
    $this->getLogger()->notice("Your config is outdated!");
    $this->getLogger()->info("Your old config.yml is renamed as old-config.yml");
    @rename($this->getDataFolder(). 'config.yml', 'old-config.yml');
    $this->saveResource("config.yml");
   
}

Happy Coding!
